      (c) Removal and restoration of high type improvements such as driveways, sidewalks, patios etc.  Where high type improvements such as concrete or asphaltic concrete driveways, sidewalks, patios, etc., are encountered the entire work shall be accomplished as outlined in high type pavements above.  Payment will fall into the payment as classified by surface type above.

            In the event that classification of original pavement quality becomes an issue the prevailing standards of the Missouri Highway Department will govern replacement quality.  In the pre-bid inspection of the job the contractor shall take note of surfaces that are encountered that fall into a type that is not readily classified as above; not limited to, but such as; flag stone, ceramic tile, concrete block, brick etc.  The contractor shall protect and remove and replace with original items these types without extra compensation.  (Ord. 69, §2)

Sec. 19-77.13   Asphaltic replacement.

      (a) Asphaltic Surfacing: The work shall consist of a 2" minimum asphaltic pavement on top of a 6" primed compacted aggregate base on top of a compacted subgrade.  Subgrade shall be in general accordance with AIS specifications.

            (1)    Stabilization:  Subgrades for roadway surfacing and trench bottom shall be firm, dense, and thoroughly compacted and consolidated; shall be free from mud and muck; and shall be sufficiently stable to remain firm and intact under equipment movement.

                     Subgrades for roadway or trench bottoms which are otherwise solid, but which become mucky on top due to construction operations, shall be reinforced with crushed rock or gravel.  The finished elevation of stabilized subgrades shall into be above subgrade elevations shown on the drawings.

            (2)    Settlement: The contractor shall be responsible for all settlement of backfill, fills, and embankments which may occur within one year after final completion of the contract under which the work was performed.

                     The contractor shall make, or cause to be made, all repairs or replacements made necessary by settlement, within 30 days after notice from the engineer or owner.

            (3)    Aggregate base: The aggregate base shall consist of 6 inches of primed gravel or crushed stone after compaction.  Quantification, placement, composition, and compaction shall be as specified in Granular Material for Backfill these specifications.

      (b) Mixture:  Commercial mixture shall be used.  Contractor shall obtain engineer's approval of mix proportions, source of materials and properties.  Asphalt plant, preparation of mixture and transportation to job site shall be to Asphaltic Institute Standards.

      (c) Placement:

            (1)    Weather limitations: Bituminous mixtures shall not be placed (1) when either the air temperature or the temperature of the surface on which the mixture is to be placed is below 40°F.  (except that base courses 3 inches or more in thickness may be placed when the air temperature is 35°F)  (2) on any wet or frozen surface, or (3) when weather conditions prevent the proper handling or finishing of the mixture.  Mixtures shall not be placed during inclement weather.

            (2)    Spreading:  Asphaltic mixtures shall be placed in accordance with Asphalt Institute Standards; allowances shall be made to achieve adequate drainage to shoulders.  Pockets that allow "pooling" are unacceptable.

            (3)    Compaction:  Rolling shall begin as soon as practicable after the spreading.  The contractor shall submit to the engineer the rolling system he proposes to use for the compaction of the mixture.  Rollers shall be in good conditions, capable of operation without backlash. Steel wheel rollers shall be equipped with scrapers.  All rollers shall have a functioning water system for moistening each roller or wheel.  Base course shall be compacted to 95% of laboratory density.  Surface course shall be compacted to 98% of laboratory density.

ARTICLE II.  SEWERS

DIVISION 6.  SEWER LINES

Subdivision III.  Excavation

Sec. 19-77.14   General.

      Contained herein are the requirements for excavation and work connected therewith as required for the satisfactory completion of the project.  (Ord. 69, §2)

Sec. 19-77.15   Classification of excavated materials.

      (a) Sewer trench excavation shall be classified as either "Trench Excavation (Class A)" or "rock excavation (Class C)" and shall be paid for as stated in basis of payment and as shown on the bid form.  The MSHTD standard specifications Section 203 shall be used to define excavation type.

      (b) Excavation pits as shown on plans are for estimating purposes only by engineer/owner.  The contractor shall ascertain on site conditions and bid job accordingly.  (Ord. 69, §2)

Sec. 19-77.16   Trench excavation.

      (a) The work included under "Trench Excavation" shall comprise any necessary clearing of the line of which the sewer is to be constructed; of making all excavations of all materials of every description which may be encountered as "Trench Excavation" and/or "earth excavation" and "rock excavation"; of furnishing and placing of all shoring, sheeting and bracing which may be necessary to protect the work and to execute it; of shaping the bottom; of furnishing all equipment which may be necessary to keep the trenches free from water so that the sewers may be placed in the dry; of providing for the uninterrupted flow of surface water or sewage adjacent to the line of the work during the progress of the work so as not to interfere with the natural surface flows; of protecting all pipes, conduits, culverts, bridges and all other public and private property which may be endangered by the work; and of hauling away all surplus excavated material.

      (b) Borings when shown on the Plans are for information only.  There is not expressed or implied agreement or guarantee that the depths or character of materials are correctly shown or that conditions affecting the work will not differ from those shown on the Plans.

      (c) All excavation shall be carried out accurately to the line and grade as shown on the Plans.

      (d) If the bottom of the excavation is found to be unstable or to include ashes, cinders, refuse, vegetable or other organic materials considered unsuitable by the engineer, the contractor shall excavate and remove such unsuitable material to the depth required and backfill to the original subgrade with granular backfill, well-compacted by means of mechanical tampers or vibrators in 6 inch layers, except as noted hereinafter.  If over-excavation is required by the engineer, the quantity of such authorized additional excavation shall be determined by the engineer, and the contractor shall be paid by the owner for the over-excavation at the unit price bid for "Ditching & Backfill" and for the "Crushed Rock for Subgrade Replacement".  Any unauthorized over-excavation shall also be backfilled as described above but no payment shall be made for such over-excavation and backfilling.

      (e) All excavation shall be dewatered before any construction is undertaken therein.  Concrete shall be placed only upon dry firm foundation material and pipe shall be laid only in dry trenches.

      (f)  Trenches shall be opened in advance of pipe laying no more than is necessary for the prompt and proper performance of the work and shall in no case exceed 300 feet of open trench in advance of pipe laying on any line under construction.  (Ord. 69, §2)

Sec. 19-77.17   Limitations on width of trench.

      (a) Trenches shall be dug so that all pipes can be laid to the alignment and depth required.  The width of trenches shall be ample to permit the pipe to be laid and jointed properly and the backfill to be placed and compacted.  Additional width shall be provided where shoring or bracing is used.

      (b) In order to avoid superimposed loading in excess of the designed and specified pipe strength and to provide sufficient room for proper installation and bedding of the pipe, the trench widths for the sewer pipe sizes used shall be kept within the limits specified as follows:

              Size of Pipe              Minimum Width          Maximum Width
              8" & Below                      2' - 0"                          2' - 0"
                 10" - 12"                        2' - 0"                          2' - 6"
                     15"                            2' - 8"                          3' - 2"

      (c) The contractor may, at his option, where working conditions and rights-of-way permit, and with the approval of the engineer, excavate sewer trenches with sloping sides, but with the following limitations:

      (d) Only braced vertical trenches will be permitted in streets, alleys or easements which are paved, or in locations where the trenches are in close proximity to utilities, building, railroad tracks, or other installations which could be endangered by the excavation.

      (e) Where trenches are excavated with sloping sides for pipe sewers to be installed, the slope shall not extend below a point one foot above the extrados of the pipe, and the trench excavation below that point shall be carried out with vertical sides for widths not exceeding the maximum widths provided for in these specifications above.

      (f)  Any trench excavated with sloping side for pipe sewers which has a width at one foot above the top of the pipe in excess of the maximum trench width permitted will result in an increased load on the sewer pipe.  If slopes are allowed to extend below this level, or if the width of the trench at this level is greater than the specified maximum width, additional strengthening of the pipe is required, and accordingly, where such conditions exist, the contractor shall consult with the engineer prior to backfill to determine additional procedures required but as a minimum shall place granular fill between the bottom of the trench and the level of one foot above the intrados of the pipe from the outside of the pipe to the undisturbed sides of the trench.  No payment shall be made for such extra procedures in backfilling which shall become necessary on account of the contractor's operations in excavating trenches of excessive widths below the specified levels.

      (g) Through all tillable property, a minimum of one foot of topsoil shall be removed from the trench and stockpiled for use in backfilling the upper one foot of trench after the lower portion of the backfill has been completed.

      (h) The elevation shown on the profiles of the sewers are those of the flowline of the pipes.  In excavating the bottom of the trench in material other than material which may cause damage to pipe such as rock or rock-like material, the contractor shall place 4 inches of "Granular Bedding" under the barrel of the pipe and shall shape the trench bottom by hand to fit the lower section of the pipe, as shown on the Plans, recessing for the bell holes where the bell projects beyond the barrel of the pipe in such manner as to relieve the bell of all load.  After the pipe has been aligned, granular bedding shall be evenly deposited on both sides of the barrel up to a distance of 6 inches over the top of the pipe.  If unauthorized over digging occurs the contractor shall, at his expense, replace the excess excavation with granular bedding material.  If excavation of subgrade is in rock a minimum of 4" of granular bedding is required beneath the bottom of the sewer pipe.

      (i)  Where necessary to protect the labor, the work, or adjacent property, the contractor shall provide and install shoring.  The sides of the trench shall remain held by bracing or sheeting of either wood or steel.  Shoring shall remain in place until the backfill has proceeded to a point where it can be safely removed.  If, in the opinion of the engineer, damage is likely to result from withdrawing shoring, it shall remain in place.  Payment for all lumber left in place as order by the engineer will be paid for at the price bid per MFBM (one thousand board feet of board material) for "Lumber Ordered Left in Trench", which payment shall cover the whole cost of furnishing all material, labor, equipment, tools and all other incidentals which may be necessary for placing and leaving the lumber in the trench.  This payment shall not cover the cost of furnishing, placing and removing lumber used for bracing during construction, which need not remain in place upon completion of the backfill.  Payment for lumber used as temporary bracing shall be included in the price for "Ditching & Backfill".

      (g) Payment for "Ditching & Backfill", including backfill and surplus disposal, shall be made at the price bid for "Ditching & Backfill".  Payment shall cover the whole cost of furnishing all equipment, labor, tools, materials and all other incidentals which may be necessary for carrying out the necessary excavation, pumping and fluming and taking care of dry and storm water flows, protecting adjacent improvements, backfilling, including tamping of the backfill as herein specified, stockpiling topsoil and backfilling with topsoil where required, maintaining temporary macadam or gravel surface in satisfactory safe condition for use by traffic until the permanent pavement restoration is carried out, disposing of the surplus excavated materials, removing any existing sewers, and cleaning up of the site, including the furnishing, placing and removing of all sheeting and bracing which may be necessary during construction, but which is not ordered left in place and which is removed as the earth backfill is being carried out.

      (k) Payment shall be from centerline to centerline of manholes and for the various depths indicated as measured from the surface to the pipe flow line.  (Ord. 69, §2)

Sec. 19-77.18   Rock.

      (a) The responsibility of the contractor with respect to the use of explosives in blasting includes compliance with all laws, rules and regulations of the State, the City and the insurer; governing the keeping, storage, use manufacturer, sale, handling, transportation or other distribution of explosives.  All operations involving the handling, storage and use of explosives shall be conducted with every precaution by trained, reliable men under satisfactory supervision.  Blasts shall no be fired until all persons in the vicinity have had ample notice and have reached positions out of danger therefrom.  The contractor shall remove all earth, to allow for rock measurement, prior to blasting; and protect debree from scattering to maximum extent possible.

      (b) After a blast is fired, the contractor shall thoroughly scale the excavation, removing all loose and shattered rock or other loose material which may be dangerous to the workmen, and the excavation shall be made safe before proceeding with the work.  The fact that the removal of loose or shattered material may enlarge the excavation beyond the required limits shall not relieve the contractor from the necessity for making such removal, and the contractor shall not be entitled to compensation therefore.  Pay width for trench rock shall be trench "Minimum Width".  Also provide underground type insurance for blasting.

      (c) Where rock or other hard material occurs in the trench so that any portion of the pipe would rest on rock or hard material, the trench excavation shall be carried to a depth below the planned grade so that no rock or other objectionable hard material is closer than 4" inches to the outside of the pipe at any point.  The width of trenches shall be ample to permit the pipe to be laid, jointed, and covered properly.  (Ord. 69, §2)

Sec. 19-77.19   Excavation for appurtenances.

      (a) All structures shall be founded on undisturbed subsoil.  Unauthorized excavation below the specified structure subgrade shall be replaced by and at the expense of the contractor, with concrete.

      (b) The contractor shall make all necessary excavations for appurtenances.   Excavation shall be made in open cut to the alignment and depth as shown on the profiles and drawings except as otherwise indicated in the specifications and drawings.

      (c) In excavation for manholes, and cleanouts and similar structures, it shall be sufficient to leave at least 12 inches in the clear between their outer surfaces and the embankment or timber which may be used to hold and protect the excavation.  In all cases the clearance between the outer face of structures and the surrounding excavation shall be sufficient to allow the proper performance of the work including the plastering of exterior wall surfaces where required by the specifications or plans.

      (d) Wherever necessary to prevent caving the excavation shall be adequately sheeted, braced and drained so that workmen may work therein safely and efficiently.  Where the bottom is in rock, the excavation limits shall allow solid rock to be exposed and cleaned of all loose material and cut to a firm surface before any foundation concrete is placed.

      (e) Whenever wet or otherwise unstable soil that is incapable of properly supporting the structures, as determined by the engineer, is encountered, such soil  shall be removed to the depth required and the excavation backfilled to the proper grade with coarse sand, fine gravel, or other suitable material as may be authorized.  All excavations for structures shall be kept dry and no pipe or reinforcing steel shall be installed in water and no water shall be permitted to inundate the reinforcing steel before concrete has been placed.  All excavations shall be kept dewatered to the extent that water will not come in contact with any concrete within 12 hours after placing.  When excavations are carried below ground water elevations such excavations shall be dewatered by lowering and maintaining the ground water level at least 12 inches below such excavations during all construction, including subgrade excavation, placing of reinforcing steel or pipe, placing of concrete, plastering or masonry, and shall be maintained in a dry condition until all concrete has been placed and allowed to harden for at least 12 hours as specified above.  (Ord. 69, §2)

Sec. 19-77.20  Construction along or across highways, railroads and creeks - work adjacent to or crossing highways.

      (a) Work adjacent to highways.  Work within the right-of-way limits of state highways shall be performed in accordance with the Highway Department's requirements, such as; necessary precautions to protect traffic by use of signs, signals, flagmen, and watchmen; accomplishing work in a manner that will not interfere with traffic, highway entrances, maintenance of the highway, or drainage facilities; and materials and methods of placing and compacting backfill.  The above and other requirements of the Highway Department which differ or are in addition to those specified herein shall be performed in accordance with the Highway Department's requirements when working within the right-of-way limits of state highways.  The contractor shall also obtain necessary permits to work on the right-of-way.

      (b) Highway crossings.  The crossings under highways shall be constructed in full accordance with the State Highway Department's requirements.  The requirements of the Highway Department will govern the method and procedures of construction and materials used for the crossing.  The contractor shall obtain the requirements of the Highway Department prior to construction.  The contractor shall be reasonable for all damage to the highways due to his operations.

      (c) Railroad crossings.  Pipe crossing under, on, or thru the railroad right-of-way shall be constructed in full accordance with the railroad company's requirements.  The entire construction, including material, construction procedures, methods, etc., shall be approved by the railroad company.  Contractor shall obtain permits and requirements from the railroad prior to construction.

      (d) Sewer bridges.  Sewer bridges shall be constructed where indicated on the Plans and where the sewer crosses the creek above the creek bed.  Bridges shall consist of cast or ductile iron pipe strapped to concrete piers.  Pipe ends to be mechanical joint with a solid sleeve or transition coupling to be used to join pipe on upstream and where pipe goes into ground and couples to normal pipe used on the job.  The bridges shall be constructed as shown on the drawings.  (Ord. 69, §2)

Sec. 19-77.21   Backfilling trenches.

      (a) Backfill methods and materials shall comply with the requirements for the specific type of pipe being used.  Two different broad categories of pipe are possible: one being a rigid pipe and the other being defined as a flexible conduit type of pipe.  Pipe falling into the classification of rigid are cast and ductile iron, clay and concrete.  Flexible conduit type of pipe are plastics such as PVC pipe, which are subject to deflection control.

      (b) The backfilling of the completed pipe sewers shall commence immediately upon the completion of the sewer laying with care being taken that the operation of backfilling does not disturb the pipe joints.

      (c) All backfill to a level of 6 inches over the top of the pipe shall conform to class 1, Granular Angular, material and as further defined in "GRANULAR MATERIAL FOR BACKFILL' these specifications.

      (d) The pipe trench shall be brought to grade by filling the approximate 4" from the subgrade to the bottom of the pipe (4" in rock) by using "Granular Bedding" compacted to a firm dense bedding.  The compaction of bedding may be obtained by raking and "walking" or "Trafficking" bedding material to firm dense condition.  Placing pipe on an uncompacted, loose granular bedding is unacceptable.  Over excavation of subgrade which exceeds 6 inches will require bedding to be placed in maximum 6" lifts compacted by power ramming equipment.  Subgrade which becomes saturated with ground or surface water, because contractor has failed to accomplish dewatering as required, and otherwise becomes unsuitable or unstable shall be removed as required by the engineer/inspector and replaced in maximum 6" lifts compacted by power ramming or vibratory equipment.  No additional payment for crushed rock for subgrade replacement shall be paid for over excavation where dewatering has not been accomplished.

      (e) After the pipe has been installed the "Granular Bedding" shall be added in maximum 6" lifts to levels of the horizontal centerline of the pipe.  This material shall be compacted by "shovel slicing" the granular material the full length of each side of the pipe in lifts not exceeding 6 inches.  "Shovel slicing" shall be extensive whereby the granular material is so worked in under the horizontal centerline of the pipe for the full length of each side to whereby compaction obtained provides meaningful resistance to further shovel slicing or further settlement under workman's feet.  In placing this initial backfill of "granular bedding material" to the centerline of the pipe unacceptable will be the procedure where the granular bedding material is dumped on the pipe to depths greater than the centerline of the pipe and spread therefrom.  After completion of shovel slicing compaction to the horizontal centerline of the pipe the granular backfill shall be "walked in" the entire length, both sides such that the granular backfill is unyielding under the workman's feet.

      (f)  For flexible conduit types of plastic pipe such as PVC, ABS, or Truss pipe the remaining backfill to a point 6 inches above the top of the pipe shall be made with the same "Granular Bedding" and compacted in maximum 6" lifts to minimum 6" above top of pipe as per initial backfill to centerline of pipe.

      (g) For rigid types of pipe such as iron, concrete or clay; the remaining backfill to a point 6 inches above the top of the pipe shall be lightly compacted "Granular Bedding" to the trench walls.

      (h) At the completion of backfill to the level of 6 inches over the pipe the granular material shall be level from trench wall to trench wall.  Granular Bedding will not be as a separate bid item and the contractor shall include necessary cost elsewhere.

      (i)  Above this level excavated material from the trench will be acceptable as backfill except herein following and as noted for special locations herein below.  Care shall be taken to eliminate large clods, stones and clay masses and also organic matter within 2 feet from the top of the pipe.

      (g) Backfilling shall be completed to insure restoration of the ground surface to its original condition.

      (k) Backfill in open fields may be completed without further compaction above 6 inches over the extrados.  The fill shall be mounded over the trench to allow for future settlement.  The top one foot of backfill shall be made through tillable areas with stockpiled topsoil.

      (l)  Backfill of trenches in paved streets will be uncompacted excavated material from trenches.  Any surplus excavated material which can not be placed in trenches shall be hauled from worksite.  The final 6 inches in paved streets shall be 6" of crushed base rock per Restoration of Secondary Roads.

      (m)  It is called to contractors attention that the General Requirements, Section 01500, Item 9, "Responsibility of Contractor for Backfill Settlement" requires contractor to be responsible for maintenance of trench excavation during the 1 year guarantee period.  While these specifications require no compaction of backfill above granular material in streets it may be of contractors best interest to minimally compact and roll trenches with wheeled vehicles, (loader, grader, etc.) in the upper most depths to minimize maintenance, speed natural settling and minimize additional crushed base rock surfacing.

      (n) Where the contractor excavates below the planned subgrade for pipe lines, the over-excavation shall be backfilled with granular material well compacted in 6 inch layers.  Only granular material placed in over-excavation authorized by the engineer will be measured and paid for at the price bid per cubic yard for "Crushed Rock for Subgrade Replacement", which payment shall cover the whole cost of furnishing all materials, labor, equipment, tools and other incidentals necessary to furnish and place the granular material.  The volume to be paid for under this item shall be limited to the volume computed within the payline widths and for the depths and lengths as ordered by the engineer.  Crushed rock placed in over-excavation not authorized by the engineer shall receive no additional compensation.  Crushed rock required for stabilization of trench bottom caused by not keeping ground or surface water out of trench will not be given additional compensation.  (Ord. 69, §2)

Sec. 19-77.22   Manholes and lampholes.

      Wherever excavating is necessary beyond the external line of manholes and lampholes, these spaces shall be refilled with a suitable material.  Backfill around these will correspond to the type of backfill that exists on the adjacent pipelines.  (Ord. 69, §2)

Sec. 19-77.23   Pavement and sidewalk replacement.

      (a) All pavement, curbing, gutter, drives, patios or sidewalks removed during construction of the project for any reason shall be replaced unless otherwise shown on the drawings or directed by the engineer, the replacement construction shall conform in type, quality, and dimension to that of the portion so removed.  Replacement shall proceed as soon as possible after the sewer line work in that area is completed.

      (b) Payment will be made for items within construction limits as defined elsewhere.  Items outside construction limits that are damaged will be replaced at contractor's expense.  (Ord. 69, §2)

Sec. 19-77.24   Surface restoration.

      (a) General.  The contractor shall not allow the site of the work to become littered with trash and waste material but shall maintain same in a neat and orderly condition during the progress of the work.

            The contractor shall clean up all dirt from paved surfaces, not allowing same to pack on the roadway or create a traffic nuisance.

      (b) Cleaning up.  After completion of construction and prior to final acceptance, the contractor, at his expense, shall remove from the sites all construction equipment, all unused or waste material, all debris, and all removed material and equipment unless specifically stated otherwise.  Any existing structures above or below ground, any existing trees, shrubs, and grass in residential or pastoral areas; and any other item which during construction was removed or damaged shall be repaired to its original condition, at the contractor’s expense.  If repair to original condition is not possible, the contractor shall replace any damaged or removed item at his expense.  It is the intent of this specification that the site after construction shall be restored to its original condition as nearly as possible.

      (c) Seeding.  Unless otherwise indicated on the drawings, all areas that had existing grass prior to construction shall be fertilized, seeded, and mulched after completion of construction work.  Seeding shall be done only when soil and climatic conditions are such as to insure reasonable success.  Seeding shall not be done during periods when, in the opinion of the engineer, the soil is too wet to permit satisfactory results.

      (d) Seeding mixture.  The seeding mixture shall be proportioned by weight, and shall consist of the following varieties and quantities per acre (minimum percentages of purity and germination are listed behind each type of seed).

            40 lbs. Kentucky Blue Grass.......................... (80%-P; 70%-G)
            10 lbs. Recleaned Red Top............................ (90%-P; 85%-G)
            20lbs. Perennial Rye Grass............................ (98%-P; 90%-G)
            10 lbs. White Dutch Clover............................ (95%-P; 85%-G)

            Seed shall be of the previous year's crop, and must be entirely free from seed of Bindweed, Canada Thistle and Johnson Grass.

      (e) Fertilizer.  Fertilizer shall have an analysis of 10, 6, 4, or an approved equivalent in the pellet form.  Fertilizer shall be broadcast uniformly on the area at such a rate that each acre to be seeded shall receive a total of 160 pounds of the actual three nutrients (nitrogen, phosphoric acid, and water soluble potash) contained in the fertilizer.  (ie combined weight of N, P & K).

      (f)  Mulch.  Mulch seeded areas at rate of 100 lbs per 1,000 sq. feet spread evenly in open areas such as yards and pasture.  Mulch wooded areas, at minimum of 50 lbs per 1,000 sq. ft.  Immediately following mulching anchor by forcing mulch into soil with disc-pacher or other suitable means.

      (g) Reseeding.  If satisfactory results are not obtained, in the opinion of the engineer, the contractor will be required to reseed and refertilize those areas on which satisfactory grass cover has not been obtained.  (Ord. 69, §2)

Sec. 19-77.25   Borings.

      (a) Borings shall meet all requirements of MO. Highway and Transportation Department and contractor shall obtain necessary permits and do all work in accordance with their requirements, if boring is on their road.

      (b) Boring shall be made so that line and grade of water line may be carried continuously thru encasement.  Boring encasement to be steel pipe with a wall thickness of a minimum as per table.  Encasement to be new, unused steel pipe with yield strength of 35,000 psi conforming to ASTM A53-B.  Casing diameter to be as shown in table unless specifically bid differently in bid proposal.  Contractor may use larger casing size if he desires, but shall be responsible for any job variations encountered by this choice.

      (c) Contractor shall complete bore before other work is started so that slight misalignments can be compensated for in other work.

      (d) While quality of work is required, this job is set up with the boring done first as previously stipulated to take advantage of a relaxed specification for casing alignment and grade that is possible within the confinements of the overall project layout.

      (e) Casing shall be installed as boring equipment removes material from hole.

      (f)  Random lengths of steel casing may be used; but all ends must be V grooved-butt welded to adjacent casing pipe around the complete perimeter of the pipe.  Welds to be water tight and shall be equal to or stronger than adjacent pipe.  Casing joining procedures must be such that concentricity of the entire completed casing will be maintained.

      (g) Boring to include all work of digging bore pit, casing and all items associated therewith, for the completed job.

      (h) In some layouts part of the casing may be installed by open cut methods and attached to the ends of the bored casing.  This will be shown as a separate bid item where and if included on the job.

      (i)  Some borings under local roads, etc. may be completed without casing.  If this procedure is used a 40 piece of PVC pipe shall be used to insure that no joints exist in the bored area.  (Ord. 69, §2)

Sec. 19-77.26   PVC installed in casings.

      (a) When PVC is installed in casings the following procedures shall be followed:

            (1) The entire casing shall be installed before any pipe is inserted into the casing.  Inspection will be by lamping and a full circle shall be required to be seen to provide that the casing is concentric from end to end.

            (2) Except as specifically shown otherwise on the plans, the minimum depth to the top of the casing shall in general be 3' - 0" below the lowest level of surface being crossed.

            (3) A repair style coupling, dresser style coupling or similar device shall be installed on either side of the end of the casing in addition to the regular pipe joints to allow for future removal-repair of the PVC carrier pipe, where the pipe is a force main.

            (4) PVC carrier pipe shall be as long as possible (40 feet) to minimize the number of joints contained within the casing.  If it is possible to install PVC without a joint in the casing (because of shortness of casing length), it will be unnecessary to place PVC pipe on skids and the pipe may be laid directly on the casing.

            (5) Whenever a PVC carrier pipe joint is required within the casing the PVC shall be placed on non biodegradable skids.

            (6) To insure that pipe bell does not rest on casing use skids to support barrel of pipe.  Skids to have at least 4 runners with a shoe height of a minimum of 1 inch.  Shoe height of skid may be higher as required by bell diameter of carrier pipe.  Shoe height of skid to be of such height that pipe cannot cork screw in casing. 

Length of skid to be 4 inch minimum and be manufactured from non biodegradable material such as a plastic.

            (7) Skid support shall be spaced as shown (in table 9 below) to insure adequate support of pipe.

            (8) PVC pipe may be installed by winch drawn cable or jacking.  The force used to install the pipe must spread over the pipe end on which it bears, by use of a flat piece of wood or other similar force sustaining material.

Sec. 19-77.29   Pipe laying.

      (a) Pipe laying shall begin at the lowest point on the sewer and proceed up grade.  The intent is to build a continuous system from the lowest point so that sewage can flow by gravity through the mains being constructed and these lines placed in service in stages.  All lines that flow without the use of pump stations must be completed before lines utilizing pump stations are installed.  If multiple crews are utilized the contractor shall begin work with the second crew at a point where the first branch intersects the lowest installed or completed manhole on the line and run this branch.  The next crew shall begin with the next lowest branch etc.  The intent is to build a continuous system without skips, however intermediate starts may be allowed, that are not contiguous, only with prior approval by the engineer of an integrated job plan from the contractor that provides the owner with essentially a continuous system wherein skips are rapidly closed.  For such intermediate starts the downstream side of the manhole will be graded to daylight in the most convenient direction and without extra compensation.

      (b) The spigot end of the pipe shall be downgrade or in the direction of flow.  For those types of pipe that use a collar type of coupling, the coupling shall be placed on the first pipe to be installed and the subsequent pipe spigot shall be inserted into the coupling.  All thrust resulting from ramming pipes home shall be downstream.

      (c) All pipes shall be laid with ends butting and true to line and grade.  They shall be fitted and matched so that when laid in the work they will form a sewer with a smooth and uniform invert.  Bells or collars must be carefully cleaned before the pipes are joined.  The pipes shall be lowered so as to avoid unnecessary handling in the trench and shall be protected against impact shocks and free fall.  They shall be set firmly to line and grade and the joints made as specified heretofore.  Prior to acceptance, the pipeline shall be lamped showing a full circle.  Pipe not meeting lamping test will be rejected and must be relaid at the contractor's expense.  Lamping test will be for the sole purpose of determining whether pipe is laid such that the center line of the pipe, as laid, lies in a straight line.

      (d) Lamping is only one test of many which will be performed to determine acceptability of completed job.  All testing will not occur concurrently and other tests, described elsewhere, will also be made.  All testing will be at contractor's expense and without special pay, unless so bid.

      (e) Ends of the pipe shall be temporarily plugged at the close of each day's work with an expandable plug which will allow no infiltration.

      (f)  Pipe shall be laid with the bell or socket uphill to the required line and grade on a prepared subgrade excavated and shaped as hereinbefore described.  The prepared subgrade shall be kept free from water during the laying of the pipe.  Line and grade shall be maintained by the use of no less than three batter boards set at 25 feet intervals and a top line.  Except by special permission of the engineer, no pipe shall be laid except in the presence of an inspector.  Each pipe as laid shall be plumbed for line with a plumb bob, and graded with a grade stick for elevation.  The accuracy of the finished line and grade of the pipe shall be obtained in the preparation of the subgrade.  The use of approved laser beam equipment may be substituted for the offset stake method.

      (g) As the work progresses, the interior of the sewer shall be cleaned of all dirt or debris of any description.  Prior to placing pipe into the ditch a bell hole shall be dug at the appropriate location and proper length so the pipe may be inserted while maintaining continuous alignment.

      (h) Before laying the pipe in trench, the bottom of the trench shall be carefully graded and prepared and bell holes excavated as hereinbefore described, so the pipe shall have a uniform support along its entire length except at bell holes, and shall not be allowed to rest on hard supports through a portion of its length only.

      (i)  Pipe shall be handled and stored so that it is not damaged and shall be reinspected just prior to placing in the ditch.  Any pipe found to be damaged shall be marked and subsequently removed from the job.

      (j)  The joints shall be connected by first brushing the proper lubricant sealer solvent cement on the clean mating surfaces as recommended by the pipe manufacturer.  The spigot end shall be centered on grade into the bell end of the downstream pipe and shoved "home".  The pipes shall be jointed within a few seconds after the application of the lubricant sealer/solvent cement.

      (k) All sewer pipe shall be laid and handled so that the allowable leakage shall not be exceed as measured by the tests hereinafter described.

      (l)  All extraneous material shall be removed from the completed sewer pipes and manholes before they are accepted by the owner.

      (m)  Each size of pipe shall be measured and paid for at the corresponding unit price bid for each particular size, type and depth of pipe installed.  The length of pipe shall be the horizontal distance between the centers of manholes as measured along the alignment of the pipe.

      (n) The unit prices for pipe of the various sizes shall include all material, labor and equipment necessary to install and test the pipe, complete in place, in accordance with the Plans and Specifications, including connections to existing pipe stubs or sewers.  (Ord. 69, §2)

Sec. 19-77.30   Control of alignment and grade.

            Not all wyes for service lines have been determined prior to job start and the contractor shall keep a record of locations as laid.  In general these wyes will be placed so as to achieve a favorable location with respect to users proposed service line.

      (b) Lines, grades and stakes.  The engineer will provide the contractor with general information for the job.  The contractor will be provided a marker at the center of each manhole and permanent benchmarks sufficient to establish vertical control and the contractor shall set all points he desires in addition to these.  The contractor shall use said information to set construction stakes, and to establish lines, grades, and other points necessary to complete the construction in accordance with the contract drawings and specifications.  The contractor shall provide qualified personnel to perform the work; and shall furnish all stakes, batter boards, and other materials and supplies necessary for marking and maintaining points and lines established.

            Should contractor use laser method of controlling line and grade, as a minimum, offset staking shall be used to verify slope with ground elevations at 25 feet and 50 feet; or 50 feet and 100 feet ahead of laser setting each time laser is set.

      (c) Work done without lines or grades.  Any work done without being properly located and established by base lines, offset stakes, bench marks, or other basic reference  points located, established, or checked by the engineer, may be ordered removed and replaced at the contractor's cost and expense.

      (d) Preservation of monuments and stakes.  The contractor shall carefully preserve all monuments, bench marks, reference points and stakes, and in case of destruction of the same, will be charged with the resulting expense of replacement, and shall be responsible for any mistakes or loss of time that may be caused by their unnecessary loss or disturbance.  (Ord. 69, §2)

Sec. 19-77.35   Connection between different pipe materials.

      (a) The connection between pipes of different materials shall be made so as to insure a watertight joint.  If the manufacturer of a specific pipe type has standard fittings for adapting to the second pipe type, then these fittings shall be used.

      (b) In the absence of this, the coupling shall be made by use of a 12 inch long rubber adaptor with stainless steel radiator hose type straps with stainless steel fasteners.  Inserted between the two types of pipe shall be an adaptor bushing.  When a rubber type connector is used a concrete cradle shall be built under both pipes up to the center line of the pipe; the cradle shall extend 12 inches under each pipe.  The entire assembly shall be completed as the work progresses.  Extra compensation will not be paid for this joint.  (Ord. 69, §2)

Sec. 19-77.36   Connection of sewers to manholes.

      (a) General.  Connection of sewer lines to manholes requires special care.  Two items that are normally associated with improper construction are infiltration around the joint between the manhole and the sewer and fracture of the sewer pipe just outside the manhole.

            All sewer lines, both in and out of manholes, will be constructed with a flexible joint at the manhole.  Many proprietary products exist for this sealing purpose and if the contractor is accustomed to using a product that works and is long lifed; it will be allowed, but only, with prior approval by the engineer. 

      (b) Cast iron, PVC, ABS pipe type connections.  The general sealing procedure will be as follows: Assuming the manhole comes to the job with the pipe hole roughly gouged out, then the sewer pipe shall be inserted so that the pipe end is about 2 inches inside the inside wall of the manhole.  The sewer pipe shall be blocked-up on the outside to maintain alignment while keeping fill materials back away from the joint.  Over the pipe slip a flexible gasket such Dura Seal III from Dura Tech Inc., 1504 N. Gettysburg Ave., Dayton, Ohio 45417, phone 513-268-4649; or Press Wedge II from Press-Seal or equal device from other manufacturer.  The grout with non-shrink grout from the manhole side of the flexible connector to the jagged edges of the previously gouged-out hole in the manhole.  Care must be taken to insure that the grout flows into the ribbed edges of the flexible connector.  Treat the concrete edges of the manhole as per grout manufacturers recommendations before grouting.  Also insert a compressible flexible polyurethane rod between pipe and either side of the connector to insure that grout does not touch pipe.  In lieu of field installation the contractor may have flexible connectors pre-cast with manhole sections.

            Once the grout has set up, complete the procedure by inflating the void in the Dura Seal or driving home the Wedge in the Press Seal or as per other manufacturer's recommendations.  Then backfill around pipe near manhole as per backfill in normal sewer pipe work.

      (c) Clay pipe type connections.  When installing clay pipe, the manhole base shall be extended along the axis of the pipe, in an integral pour to create a cradle as necessary; and the flexible joint shall result at the end of this extension via the normal clay connection.  Concrete width of extended axis to be pipe OD+12 inches.  Installation of normal pipe lengths (5ft+) when building into manhole shall stop short of the manhole so that a short closure piece of pipe (18"-24") may be installed in addition to the cradles length of cut pipe.  The cradled length of pipe shall be cut so as to extend to the inside wall of the manhole.  Clay pipe shall be cut with a chain type cutter or saw to insure square cut and one that does not crack pipe.  Block pipe up to maintain alignment and fill gouged out hole between outside pipe and manhole concrete with nonshrink grout.

            Complete concreting around pipe that lays over cradle so that entire pipe is covered with concrete up to flexible joint.  When going out of a manhole, closures shall be made similarly with the concrete cradle extending a length of 24+ inches to encase the first piece of pipe installed.  Then a 2 foot length of pipe shall be installed and then normal pipe lengths shall be installed.  Backfill around pipe near manhole as per backfill in normal sewer pipe work.  (Ord. 69, §2)

Sec. 19-77.37   Construction of manholes, lampholes and appurtenances.

      (a) Manholes.

            (1)    General.  The manholes shall be built on the line of the sewer at such points and to such depths as are indicated on the Plans, and shall conform in all respects to the detailed plans for manholes of the types specified.  When a manhole is built in a location that has been improved such as streets, roads, drives, mowed lawns or other such locations then the tops of the manholes shall be brought flush with the finished grade of said improvement.  The top of the casing shall slope as necessary to conform as nearly as possible to the existing surface.  Slopes may be built by use of sewer brick mortar if the slope is severe or by mortar alone for gentler slopes.  Tops of manholes in open fields or other unimproved areas shall be extended to the surface elevation as a minimum.  The contractor at his option, where not otherwise specified or shown on plans, may extend the top of the manhole to an approximate six inches above the ground surface to facilitate using precast manhole sections.

            (2)    Construction.  Manholes shall have 4' - 0" inside diameter and 2' - 0" opening at top.  Manholes shall be constructed of precast concrete or poured in place concrete.  Manhole shall be built so that the axis of the manhole is aligned and plumb.

            Precase concrete manhole sections shall be built with 5" minimum thick wall reinforced in accordance with ASTM C-478 Class II tongue and groove joint.  Use joint mastic of all weather butyl in 1 inch diameter rope from for all joints, 2 rings per joint.  Precase sections to be set so that outside wall of top manhole pipe is lower than inside wall of bottom manhole pipe.  Eccentric cone sections approximately 3' long shall be used as transition piece to bring inside manhole diameter from 4 feet to 2 feet.

            Manhole sections shall be cast in standard dimensions of 16 inch, 24 inch, 32 inch or 48 inches and these together with the eccentric cone section shall be used to bring manhole top, including dimensions for the CI rings, as nearly equal to the surface as possible.  Tongue and groove style adjustment and/or grade rings shall be used to further bring the top to grade.  Slopes to bring top to conform to surface profile shall be built as outlined previously.

            No more than one grade ring shall be used on top of cone section to accomplish finished plan grade, except if grade rings are of T & G Construction - then more than 2 may be stacked.

            Cast in place manholes shall have a minimum wall thickness of 6 inches and must receive the engineers approval of the specific details obtained by use of contractors forms.

            (3)    Concrete foundation.  The concrete foundations shall be not less than 9 inches in thickness below the bottom of the pipe sewer.  A channel conforming to the bottom half of the pipe sewer shall be provided with a vertical wall to the depth of not less than 5/8th of the height of the outlet pipe.  The floor shall rise 3 inches from the edge of the channel to the wall of the manhole.  The inverts of all manholes located at changes in alignment of the sewer shall be shaped to the incoming and outgoing pipes and smoothly curved from pipe to pipe to the top of invert at springline.

                     (i)     Poured-in-place Concrete Foundation: Poured in place bottoms shall be constructed of 3500 psi concrete per CONCRETE & REINFORCING STEEL* - these specifications and shall be placed on firm, dry, excavated stable subgrade.  The pre-cast bottom section shall be set in place on concrete or brick blocks to the precise grade with piping installed and checked to insure proper grade thru manhole.  Bottom foundation shall then be poured to a depth which will completely seal and support the precast sections.  The contractor may at this time also shape invert during this concrete placement operation.  After foundation has set a minimum of 72 hours the remainder of the sections may be placed a-top the bottom section.

* Subdivision V - Sec. 19-77-45.

                     (ii)    Precase Concrete Foundations: Precast bottoms shall be precast monolithic with pipe sections to dimensions as shown on plans.  If bottoms are precast they shall extend beyond the outside wall a minimum of 4 inches to provide greater stability.

                              Placement of precast bottom sections shall be on a compacted granular base.  The sub-grade shall be firm and dry prior to any placement of base rock.  Subgrade that has become wet or mucky shall be removed.  A sub-grade which has become slightly mucky may be stabilized with 2" crushed stone worked into subgrade until it is dense, firm, and unyielding and "non-pumping".  Base rock placed on subgrade or stablized subgrade shall be placed and compacted in 4 to 6" lifts to finished base grade.  Compaction to be to an approximate 90% Proctor Density with mechanical power or vibratory tamper.  The finished base shall be hand raked & uniformly even prior to placing precast bottom.  Flow lines shall be checked with level for fall immediately after placement of bottom section.  If placement of bottom section is determined to be unacceptable, it shall be completely removed from excavation and base rock grade shall be adjusted to correct grade.  If the correction involves additional base rock, this additional base shall be placed and compacted prior to replacement of bottom section.  Unacceptable will be a method whereby raking or adding base rock under a suspended bottom section occurs where inspector can not observe the uniformity of the base prior to placement of the bottom section.  Bottom section of manholes shall be backfilled and checked again for correct elevations and flow thru the section prior to placing subsequent sections on top of base section.  Care shall be exercised during backfill of remainder of manhole so that side pressures are uniform and manhole is not displaced from the original placement.

      (c) Sewers near water lines

            (1)   Horizontal Separation: Whenever possible, sewers shall be laid at least 10 feet horizontally from any existing or proposed water main.  If local conditions prevent lateral separation of 10 feet, the sewer line may be laid closer than the 10 feet to the water main if:

                   (i)    It is laid in a separate trench, or if

                   (ii)  It is laid in the same trench with the water main located at one side on a bench of undisturbed earth, and if

                   (iii) In either case the elevation of the top (crown) of the sewer is at least 18 inches below the bottom (invert) of the water main..

            (2)   Vertical Separation: Whenever sewers must cross under water mains, the sewer shall be laid at such an elevation that the top of the sewer is at least 18 inches below the bottom of the water line.  When the elevation of the sewer cannot be varied to meet the above requirements, the water main shall be relocated to provide this separation, or constructed with mechanical joint pipe for a distance of 10 feet on each side of the sewer.  One full length of water main shall be centered over the sewer so that both joints will be as far from sewer as possible.

            (3)   Unusual Conditions: Whenever it is impossible to obtain proper horizontal and vertical separation as stipulated above, both the water line and the sewer shall be constructed of mechanical joint cast iron pipe and shall be pressure tested to assure water-tightness.  (Ord. 69, §2)

Subdivision VI.  Acceptance Tests for Sewers

Sec. 19-77.47   Testing.

      The contractor shall provide all material, equipment, and devices for the testing of the force main and gravity sewers.  Testing shall be according to State Regulations and as described herein.  (Ord. 69, §2)

Sec. 19-77.48  Acceptance tests for gravity sewers.

      (a) Infiltration-Exfiltration.  Upon completion of a section of the sewer, the contractor shall de-water it and conduct a satisfactory test to measure the infiltration for at least two hours.  The amount of infiltration, including manholes, Y-branches, and connections shall not exceed 200 gallons per inch diameter per mile of sewer per 24 hours.  The contractor shall be responsible for the satisfactory water-tightness of the entire section of sewer and shall satisfactorily repair all joints or other locations that are not sufficiently water tight.  Ground water for infiltration tests shall be a minimum of two feet above top of pipe at its upper end.

            As required, suitable bulkheads shall be installed to permit the test of the sewer.

            Where the ground water level is less than two feet above the top of the pipe at its upper end, the sewers shall be subjected to an internal pressure by plugging the pipe at the lower end and then filling the pipelines and manholes with clean water to a minimum height of 2 feet above the top of the sewer at its upper end.  No section of competed sewer shall be tested with an internal pressure of over 10 feet.

            The rate of leakage from the sewers shall be determined by measuring the amount of water required to maintain the level 2 feet above the top of the pipe for a period of at least 2 hours, commencing one hour after the pipeline filling is completed.

            Leakage from the sewers under test shall not exceed the requirements for leakage into sewers as hereinbefore specified.

            Manholes shall be considered as a pipe of equivalent diameter and tested appropriately.  Air testing of sewer pipe as an alternate to water testing will not negate need of testing manholes to include all barrel joints.

            The contractor shall provide weirs or other means of measurements as may be required, shall furnish water and shall do all necessary pumping to enable the tests to be properly made.

            Where ground water is greater than 2 feet above top of pipe infiltration into sewers shall be measured within the same allowances as exfiltration.  In this case the sewer shall be dewatered and isolated such that flows may be observed with respect to this infiltration.

      (b) Alternate air testing of gravity sewers.  Air testing will follow the Uni Bell procedure on pages 346.43 & 346.44.  Air testing is an alternate (contractors option to use as a base) procedure unless excessive failures are encountered via water testing.  Excessive failures shall be defined as 1 failure out of the first 3 tests.

            Plug each end and introduce air at a pressure not to exceed 4 psi, allow to stabilize at 3.5 psi.  Measure the time it takes the pressure to drop from 3.5 to 2.5 psi.  Compare against calculated time by the formula.

            If measured test time is less than that calculated, the line falls and must be repaired at contractors expense.

            Where air testing is used by contractor as an alternate to water testing sewer lines, the contractor shall additionally be required to water test manholes separately to include all barrel joints.

      (c) Water testing of focemain.  Prior to performance of the test all air shall be expelled from the pipeline.  This may be accomplished by means of air relief valves, blow-off valves, or other means.  Such taps shall be plugged after testing is complete.

            Apply a test pressure of not more than 30% above systems pipe rated pressure.  After the specified pressure has been reached the pump shall be stopped and all pipe, and appurtenances examined for leaks.  Any visible leaks shall be repaired.  After visible leaks are repaired the pipe line shall be refilled with water and repressurized.  This pressure shall be maintained for a period of four hours.  After test period measured water shall be pumped into the line to bring pressure back to original and acceptability determined by formula.

            "Leakage shall not exceed 10 gallons per inch of pipe diameter per mile of pipe per 24 hours".

            The system may be tested in whole or part as suits the contractors need, however the engineer may request the contractor to complete the test on a portion of the system if he so desires.

      (d) Deflection.  Not less than 30 days after backfill and not more than 60 days all flexible type pipe ie (PVC ABS, Truss) shall have a deflection test made on it.  All pipe with a deflection over 5% shall be rejected and replaced at the contractors expense.  The test shall be run by use of a GO-NOGO Mandrel.  The contractor shall pull the mandrel thru the pipe without mechanical pulling devices.  The OD of the mandrel shall be 95% of pipe inside diameter.  Mandrel design and certification to be submitted by contractor for engineer's approval.  (Ord. 69, §2)

Sec. 19-77.49   Repairs.

      Should the sections under test fail to meet the requirements, the contractor shall do all work of locating and repairing leaks and retesting without additional compensation until acceptable.  Separate payment will not be made for this work and the contractor shall include price elsewhere.

      (a) Material submittal requirements:
            Aggregate certification

DIVISION 4.  CROSS CONNECTION CONTROL

Sec. 19-125.  Cross connection control - General policy.

      (a) Purpose.  The purpose of this Division is:

(1) To protect the public potable water supply from contamination or pollution by containing within the consumer's internal distribution system or private water system contaminants or pollutants which could backflow through the service connection into the public potable water supply system.

(2) To promote the elimination, containment, isolation, or control of existing cross connections, actual or potential, between the public or consumer's potable water system and nonpotable water systems, plumbing fixtures, and industrial-process systems.

(3) To provide for the maintenance of a continuing program of cross connection control which will systematically and effectively prevent the contamination or pollution of all potable water systems.

      (b) Application.  This Division shall apply to all premises served by the public potable water system of the City of Vienna.

      (c) Policy.  This Division will be reasonably interpreted by the water purveyor.  It is the water purveyor's intent to recognize the varying degrees of hazard and to apply the principle that the degree of protection shall be commensurate with the degree of hazard.

      The water purveyor shall be primarily responsible for protection of the public potable water distribution system from contamination or pollution due to backflow or contaminants or pollutants through the water service connection.  The cooperation of all consumers is required to implement and maintain the program to control cross connections.  The water purveyor and consumer are jointly responsible for preventing contamination of the water system.

      If, in the judgement of the water purveyor or his authorized representative, cross connection protection is required through either piping modification or installation of an approved backflow prevention device, due notice shall be given to the consumer.  The consumer shall immediately comply by providing the required protection at his own expense; and failure, refusal, or inability on the part of the consumer to provide such protection shall constitute grounds for discontinuing water service to the premises until such protection has been provided.  (Ord. 37, §1.)

Sec. 19-126.  Definitions.

      The definitions listed in Appendix A shall apply in the interpretation and enforcement of this Article.  (Ord. 37, §2)

Sec. 19-127.  Cross connection prohibited.

      (b) No connection shall be installed or maintained whereby an auxiliary water supply may enter a public potable or consumer's water system unless such auxiliary water supply and the method of connection and use of such supply shall have been approved by the water purveyor and the Missouri Department of Natural Resources.

      (c) No water service connection shall be installed or maintained to any premises in which the plumbing system, facilities, and fixtures have not been constructed and installed using acceptable plumbing practices considered by the water purveyor as necessary for the protection of health and safety.  (Ord. 37, §3)

Sec. 19-128.  Survey and investigations.

      (a) The consumer's premises shall be open at all reasonable times to the water purveyor, or his authorized representative, for the conduction of surveys and investigations of water use practices within the consumer's premises to determine whether there are actual or potential cross connections to the consumer's water system through which contaminants or pollutants could backflow into the public potable water system.

      (b) On request by the water purveyor or his authorized representative, the consumer shall furnish information on water use practices within his premises.

      (c) It shall be the responsibility of the water consumer to conduct periodic surveys of water use practices on his premises to determine whether there are actual or potential cross connections to his water system through which contaminants or pollutants could backflow into his or the public potable water system.  (Ord. 37, §4)

Sec. 19-129.  Type of protection required.

      (a) The type of protection required by this Division shall depend on the degree of hazard which exists, as follows:

(2) An approved air gap separation or an approved reduced pressure principle backflow prevention device shall be installed where the public potable water system may be contaminated with a substance that could cause a system or health hazard.

(3) An approved air gap separation or an approved reduced pressure principle backflow prevention device or an approved double check valve assembly shall be installed where the public potable water system may be polluted with substances that could cause a pollutional hazard not dangerous to health.  (Ord. 37, §5)

Sec. 19-130.  Where protection is required.

      (a) An approved backflow prevention assembly shall be installed on each service line to a consumer's water system serving premises where, in the judgment of the water purveyor or the Missouri Department of Natural Resources, actual or potential hazards to the public potable water system exist.  The type and degree of protection required shall be commensurate with the degree of hazard.

      (b) An approved air gap separation or reduced pressure principle backflow prevention assembly shall be installed at the service connection or within any premises where, in the judgment of the water purveyor or the Missouri Department of Natural Resources, the nature and extent of activities on the premises, or the materials used in connection with the activities, or materials stored on the premises, would present an immediate and dangerous hazard to health should a cross connection occur, even though such cross connection may not exist at the time the backflow prevention device is required to be installed.  This includes but is not limited to the following situations:

(1) Premises having an auxiliary water supply, unless the quality of the auxiliary supply is acceptable to the water purveyor and the Missouri Department of Natural Resources.

(2) Premises having internal cross connections that are not correctable, or intricate plumbing arrangements which make it impractical to ascertain whether or not cross connections exist.

(4) Premises having a repeated history of cross connections being established or reestablished.

(5) Premises, which due to the nature of the enterprise therein, are subject to recurring modification or expansion.

(6) Premises on which any substance is handled under pressure so as to permit entry into the public water supply, or where a cross connection could reasonably be expected to occur.  This shall include the handling of process waters and cooling waters.

(7) Premises where materials of a toxic or hazardous nature are handled such that if backsiphonage or backpressure should occur, a serious health hazard may result.

      (c) The types of facilities listed in Appendix B fall into one or more of the categories of premises where an approved air gap separation or reduced pressure principle backflow prevention assembly is required by the water purveyor and the Missouri Department of Natural Resources to protect the public water supply and must be installed at these facilities unless all hazardous or potentially hazardous conditions have been eliminated or corrected by other methods to the satisfaction of the water purveyor and the Missouri Department of Natural Resources.  (Ord. 37, §6)

Sec. 19-131.  Backflow prevention assemblies.

      (a) Any backflow prevention assembly required to protect the facilities listed in Appendix B shall be of a model or construction approved by the water purveyor and the Missouri Department of Natural Resources.

 (1)      Air gap separation to be approved shall be at least twice the diameter of the supply pipe, measured vertically above the top rim of the vessel, but in no case less than one inch.

(2) A double check valve assembly or a reduced pressure principle backflow prevention assembly shall be approved by the water purveyor, and shall appear on the current "list of approved backflow prevention assemblies" established by the Missouri Department of Natural Resources.

      (b) Existing backflow prevention assemblies approved by the water purveyor at the time of installation and properly maintained shall, except for inspection and maintenance requirements, be excluded from the requirements of this Division so long as the water purveyor is assured that they will satisfactorily protect the water system.  Whenever the existing assembly is moved from its present location, or requires more than minimum maintenance, or when the water purveyor finds that the maintenance constitutes a hazard to health, the unit shall be replaced by a backflow prevention assembly meeting the requirements of this Division.  (Ord. 37, §7)

Sec. 19-132.  Installation.

      (a) Backflow prevention devices required by this Division shall be installed at a location and in a manner approved by the water purveyor and shall be installed at the expense of the water consumer.

      (c) Hazard, pollutional - an actual or potential threat to the physical properties of the water system or to the potability of the public or the consumer's potable water system but which would constitute a nuisance or be aesthetically objectionable or could cause damage to the system or its appurtenances, but would not be dangerous to health.

      (d) Hazard, system - an actual or potential threat of severe damage to the physical properties of the public potable water system or the consumer's potable water system, or of a pollution or contamination which would have a protracted effect on the quality of the potable water in the system.

      "Industrial process system" means any system containing a fluid or solution, which may be chemically, biologically, or otherwise contaminated or polluted in a form or concentration such as would constitute a health, system, pollutional, or plumbing hazard if introduced into a potable water supply.

      "Isolation" means protection of a facility service line by installing a cross connection control device or air gap separation on an individual fixture, appurtenance, or system.

      "Pollution" means the presence of any foreign substance (organic, inorganic, or biological) in water which tends to degrade its quality so as to constitute a hazard or impair the usefulness of the water to a degree which does not create an actual hazard to the public health but which does adversely and unreasonably affect such waters for domestic use.
