629.05 EXCAVATION . Where the pipe is to be laid below the existing ground line, a trench shall be

excavated to the required depth and to a width sufficient to allow for joining of the pipe. The bedding and backfill material under and around the pipe sha ll be compacted per the applicable material specification. Where feasible, trench walls shall be vertical. The completed trench bottom shall be firm for its full length and width. Ledge rock, rocky or gravelly soil, hardpan, or other unyielding foundation material encountered at the normal grade of the pipe bed shall be removed and replaced with granular backfill for structures. The width of the pipe bed shall be equal to the inside diameter of the pipe plus 36 inches. The minimum depth shall be 12 inches b elow the pipe grade, unless otherwise shown on the Plans or directed by the Engineer. No tunneling will be permitted except with the written approval of the Engineer. Permission to tunnel will be granted only in short sections where, in the opinion of the Engineer, the pipe can be safely and properly installed and the backfill properly compacted. 6-119 The Contractor shall conduct operations to prevent the accumulation of water, ice, and snow in excavations or near excavated areas, and to pre vent water from interfering with the progress or quality of the work at all times. Under no conditions shall water be allowed to rise in open trenches after the pipe has been placed. Accumulated water, ice, and snow shall be promptly removed and disposed o f by pumping or other approved means. Disposal shall be carried out in a manner which will not create a hazard to public health; cause injury to public or private property, work completed or in progress, or public streets; or cause any interference in the use of streets and roads by the public. Pipes under construction shall not be used for drainage of excavations. Where pipes are to be placed in embankment fill, the excavation shall be made after the embankment has been completed to a height of 3 feet plus one pipe diameter above the designed grade of the pipe. Sheeting and bracing required for trenches shall be removed to the elevation of the pipe, but no sheeting will be allowed to be pulled, removed, or disturbed below the pipe.

629.06 BEDDING FOR PIPE . Ductile iron pipe shall be laid on suitable soil and backfilled and

compacted to the centerline of the pipe with select material. Select material shall be sand, crushed stone bedding, or suitable material excavated from the trench, and free from rocks, fo reign materials, and frozen earth. Seamless copper tube shall be bedded and covered with sand borrow. Concrete cradle bedding shall be installed on approved subgrades when shown on the Plans or directed by the Engineer.

629.07 LAYING PIPE . Installation of all water lines shall be in accordance with ANSI/AWWA C600,

Recommended Standards for Water Works , Recommended Standards for Wastewater Facilities , and the standards of the Vermont Drinking Water and Ground Water Protection Division. Pipe laying shall begin at the outlet end. The lower segment of the pipe shall be in contact with the shaped bedding throughout its full length. Bell or grooved ends of rigid pipes and the circumferential laps of flexible pipe shall be placed facing upstream. The long itudinal laps or seams of flexible pipe shall be at the sides. All pipes and fittings shall be carefully examined for defects, and no pipe or fittings that are known to be defective shall be laid. If any defective piece is discovered after laying, it shall be removed and replaced at the Contractor’s expense. All pipes and fittings shall be cleaned before they are laid and shall be kept clean until accepted in the completed work. 6-120 The pipe shall be laid to conform to the lines and grades indicated on the Plans or as directed by the Engineer. Each pipe shall be so laid as to form a closed joint with the next adjoining pipe and to bring the inverts continuously to the required grade. Each length of pipe shall be driven home against the pipe previously laid and held securely in posi tion. Joints shall not be pulled or cramped unless permitted by the Engineer. Before any joint is made, the pipe shall be checked to ensure that a closed joint with the next adjoining pipe has been maintained and that the inverts are matched and conform to the required grade. The pipe shall not be driven down to grade by striking it. The Contractor shall take all necessary precautions to prevent flotation of the pipe in the trench. When pipe laying is not in progress, the open ends of the pipe shall be clos ed with temporary watertight plugs. If water is in the trench when work is resumed, the plug shall not be removed until all danger of water entering the pipe is eliminated. The use of concrete reaction blocking shall be limited to caps, tees, hydrants, and bends of 22.5° and greater. Blocking shall be placed only on the sides of each fitting in the direction of thrust and not underneath for use as a foundation or support. All other bends less than 22.5° shall be restrained by use of retainer glands at each bend and at all joints within three pipe lengths on each side of the bend. Separation of water mains and sewers shall conform to the requirements of Subsection 628.1 4.

629.08 JOINING PIPE . Water pipe shall be joined in accordance with the detailed instruc tions of the

manufacturer. Where recommended by the manufacturer, the Contractor shall furnish coupling pullers for joining the pipe. Gasket feeler gauges shall be available for use by the pipe layer and the Engineer for checking the position of the rubber gaskets in the completed joint, if so directed by the Engineer. The electrical conductivity of the pipeline and attached services shall be maintained at all joints, couplings, valves, and fittings through the use of three brass wedges at each joint, or wi th conduction straps. No couplings shall be made at any point on the pipeline or attached services without incorporating provisions to maintain electrical conductivity. Any fittings showing a crack, and any fitting or pipe which has received a severe blow that may have caused a fracture, even though no such fracture can be seen, shall be marked as rejected and removed immediately. Water pipe shall be cut by means of a handsaw, metal -inserted abrasive wheels, or by pipe cutters with blades, not rollers, doin g the cutting. All cut ends shall be examined for possible cracks caused by cutting. 6-121 629.09 SETTING OF VALVES AND FITTINGS . Valves, fittings, plugs, and caps shall be set and joined to pipe in the manner specified above for laying and joining pipe. A valve box shall be provided for every valve that has no gearing or operating mechanism or in which the gearing or operating mechanism is fully protected with a gear case. The valve box shall not transmit shock or stress to the valve and shall be centered a nd plumb over the wrench nut of the valve, with the box cover flush with the surface of the finished pavement or other such level as directed by the Engineer. A masonry valve pit shall be provided for every valve that has exposed gearing or operating mecha nisms. The valve nut shall be readily accessible for operation through the opening in the manhole, which shall be set flush with the surface of the finished pavement, or such other level as specified by the Engineer. Pits shall be constructed to permit min or valve repairs and afford protection to the valve and pipe from impact where they pass through the pit walls. Mains shall be drained through drainage branches or blow -offs to dry wells from which the water can be pumped. Drainage branches, blow -offs, air vents, and appurtenances shall be provided with valves and shall be located and installed as shown on the Plans. Drainage branches or blow -offs shall not be connected to any sewer, submerged in any stream, or be installed in any other manner that will per mit back siphonage into the distribution system. All dead ends of new mains shall be closed with plugs or caps and shall be equipped with suitable blow - off facilities. Corporation stops shall, in all instances, be tapped into the main on the side in a horizontal position or in such a position as will provide a minimum of 5 feet of cover over the connecting service line. The main shall be tapped by skilled workers and the stop installed in accordance with the manufacturer’s recommendations at the locations shown on the Plans or as directed by the Engineer. The stops may be installed later, at which time the main may be tapped under pressure. All defective taps shall be rep aired or replaced at the Contractor’s expense. Prior to installation, the Contractor shall thoroughly clean all exposed portions of any valves, removing all labels and all traces of foreign substance using only a cleaning solution approved by the manufactu rer of the valve and being careful to avoid all damage to surfaces and coatings.

629.10 SETTING OF HYDRANTS . Hydrants shall be located as shown on the Plans or as directed so as

to provide complete accessibility and minimize the possibility of damage from vehicles or injury to pedestrians. 6-122 When placed behind the curb, the hydrant barrel shall be set so that no portion of the pumper or hose nozzle cap is less than 6 inches or more than 12 inches from the gutter face of the curb. When set in the area bet ween the curb and the sidewalk, or between the sidewalk and the property line, no portion of the hydrant or nozzle cap shall be within 6 inches of the sidewalk. All hydrants shall stand plumb and shall have their nozzles parallel with, or at right angles t o, the curb, with the pumper nozzle facing the curb, except hydrants having two hose nozzles 90° apart shall be set with each nozzle facing the curb at an angle of 45°. Hydrants shall be set to the established grade, with nozzles at least 12 inches above t he ground, as shown or as directed by the Engineer. Each hydrant shall be connected to the main with a 6 inch or larger branch controlled by an independent gate valve, unless otherwise specified. If, as determined by the Engineer, the waste opening of any hydrant will be below the normal sub -surface water elevation, the waste opening shall be securely plugged and no drainage pit will be required. Wherever a dry -barrel hydrant is set in soil that is pervious, drainage shall be provided at the base of the hydrant by placing coarse gravel or crushed stone mixed with coarse sand, from the bottom of the trench to at least 6 inches above the waste opening in the hydrant, and 12 inches around the elbow. No drainage system shall be connected to a sewer. Wherever a d ry-barrel hydrant is set in clay or other impervious soil, a drainage pit 24 inches wide × 24 inches long × 36 inches deep shall be excavated below each hydrant and backfilled with coarse gravel or crushed stone mixed with coarse sand, and compacted under and around the elbow of the hydrant to a level of 6 inches above the waste opening. No drainage pit shall be connected to a sewer.

629.11 ANCHORAGE . The bowl of each hydrant shall be well braced against unexcavated earth at the

end of the trench with ston e slabs or concrete backing, or the hydrant shall be tied to the pipe with suitable metal tie rods, clamps, or retainer glands as shown on the Plans or directed by the Engineer. All plugs, caps, tees, and bends, unless otherwise specified, shall be provide d with a reaction backing, or movement shall be prevented by attaching suitable metal rods or clamps as shown or specified. Concrete reaction backing shall be placed between solid ground and the fitting to be anchored; the area of bearing on the pipe and o n the ground in each instance shall be that shown on the Plans or directed by the Engineer. The backing shall, unless otherwise shown or directed, be placed in such a manner as to contain the resultant thrust forces in such a way that the pipe and fitting joints will be accessible for repair. A metal harness of tie rods, clamps, or retainer glands of adequate strength to prevent movement may be used instead of concrete backing, as directed by the Engineer. Steel rods or clamps shall be galvanized or otherwi se rust proofed, or shall be painted as shown in the Plans or directed by the Engineer. 6-123 629.12 PRESSURE AND LEAKAGE TESTS . Except as otherwise directed, all pipelines shall be tested. Pipelines laid in excavation or bedded in concrete shall be tested prior to field painting. Pipe to be insulated shall be tested prior to installing insulation. The Contractor shall furnish all gauges, testing plugs, caps, and all other necessary equipment and labor to perform leakage and pressure tests in sections of an approved length. Each valved section or a maximum length of 1,000 feet of pipe shall be tested. The Contractor shall provide and bear the costs of any additional taps to the waterline necessary to perform the pressure and leakage test between valves . All water required for testing shall be potable. All testing shall be conducted in the presence of the Engineer. The Contractor shall make the necessary provisions to tap the pipe at the high point to release all air and shall plug the pipe after complet ing the test. Hydrants or blow -offs located at high points may be used for air release instead of taps if approved by the Engineer. For the pressure test, the Contractor shall develop and maintain for two hours, 150% of the working pressure measured in pou nds per square inch. Failure to hold the designated pressure for the two -hour period will constitute a failure of the section tested. The leakage test shall be performed for a duration of two hours, only after the pressure test has been satisfactorily comp leted. During the leakage test, the Contractor shall measure the quantity of water required to maintain the maximum operating pressure of the main. Leakage shall not exceed allowable values for leakage presented in ANSI/AWWA C600 , Table 6B . All testing sha ll be conducted in accordance with ANSI/AWWA C600 . Should any section of pipe fail either the pressure or leakage test, the Contractor shall do everything necessary to locate and repair or replace the defective pipe, fittings, or joints at no expense to th e Agency. If for any reason the Engineer should alter the foregoing procedure, the Contractor shall remain responsible for the tightness of the line within the above requirements for the duration of the tests.

629.13 DISINFECTING . Before being placed in s ervice, the pipeline, valves, hydrants, etc., shall be

chlorinated in accordance with ANSI/AWWA C651 . The entire procedure for chlorinating the pipes shall be approved by the Engineer 14 calendar days prior to the time the work is performed. The location o f chlorination and sampling points will be determined by the Engineer in the field. The general procedure for chlorination shall be to first flush out the lines until all dirty or discolored water has disappeared, then to apply the chlorine in approved dos ages through a tap at one end of the line while water is being drawn at the other extremity of the line until the entire line contains chlorine solution. The chlorine solution shall remain in the pipeline for a period of 24 hours. 6-124 Within 24 hours followi ng the chlorination period, all treated water shall be flushed from the lines or portions thereof at their extremities and replaced with water from the distribution system. Special disinfecting procedures shall be used as directed by the Engineer where the above outlined method is not practical, and when making connections to existing mains. The Contractor shall provide all necessary apparatus, materials, and labor for disinfecting the mains and shall make the required taps for this purpose. Disinfection of the mains shall be under the immediate direction of the Engineer during all phases of the work. Prior to being placed in operation for domestic use, all new portions of the system shall be flushed, pressure tested, disinfected, and flushed again. Followin g this procedure, at least two water samples shall be collected from representative sample points and sent to the Vermont Department of Health laboratory , or another testing laboratory approved by the Vermont Department of Health, for bacteriological testi ng. Passing sample results are required before the system may be placed on line for drinking. Sample bottles shall be obtained from the same laboratory.

Sufficient slack shall be left adjacent to the corporation stop and curb stop to prevent damage to the copper tubing by movement of the pipeline. Care shall be exercised in the placing and laying of copper tubing to be sure that the pipe does not have kinks or lie directly on sharp stones or ledge which would cause damage to the pipe. The Contractor shall place at least 6 inches of selected material as approved b y the Engineer, adjacent to, above, and below the tubing. In making cuts in copper service pipe, a cutter or tool designed for tube cutting shall be used. The tubing shall be reamed and after placing the coupling nut on the pipe, the pipe shall be flanged using a flanging tool designed particularly for this purpose and connected. A compression fitting may also be used. All services shall be tested for leakage and , in all instances, the corporation stops shall be left in the open position upon completion of the installation. 6-125 The Contractor shall install the curb stop and the curb box at the end of the service line, usually at the approximate property line, or a s shown on the Plans and connect the stop to the water main with new copper tubing. The curb box shall be installed vertically and centered over the operating key, with the elevation of the top adjusted to conform to the finished grade. The Contractor shal l adequately support the curb box during backfilling to maintain its vertical alignment. The Contractor shall also ensure that the curb box does not rest on the curb stop owner’s services and furnish any adapters or special couplings needed for these conne ctions. Any necessary piping from the curb stop to the existing service shall match the existing service line, unless otherwise directed by the Engineer.

This material shall be sand, gravel, or crushed stone and shall not contain large lumps or stones larger than 1 inch in diameter. The Engineer may direct the use of material meeting the requirements for granular backfill for structures. As the pipe is laid, bedding material shall be extended to the spring line of the pipe and leveled along the width of the trench. The pipe installation shall be inspected and approved by the Engineer before being covered.
c.Pipe Envelope Area . The pipe envelope consists of selected suitable material placed from the spring line of the pipe to a depth of 12 inches over the top of the pipe. The material shall be carefully placed and spread over the width of the trench and compacted using an approved tamper. The Contractor shall take necessary precautions during placement and compaction of the bedding and pipe envelope materials to prevent either damage to or displacement of the pipe. 6-126 (d) Above Envelope Area . Unless otherwise shown on the Plans, material used for backfilling trenches above the envelope area shall be suitable material that was removed during excavation, or obtained from borrow, and when compacted shall make a dense stable fill. The material shall not contain vegetation, porous mat ter, or stones larger than 6 inches in the widest dimension. If additional material is required, it shall be furnished from approved sources. Backfill material shall be evenly spread and compacted in lifts not more than 6 inches thick or as approved by the Engineer. Previously placed or new material shall be moistened by sprinkling, if required, to ensure proper bond and compaction and shall con form to the requirements of Subsection 203.11(d) . When compacting backfill, care shall be taken that stones and lumps shall not become nested and that all voids between stones shall be completely filled with fine material. No compacting shall be done whe n the material is too wet to be compacted properly. If the material is too wet, the work shall be suspended until the previously placed and new materials have dried out sufficiently to permit proper compaction, or until other precautions are taken as neces sary to obtain proper compaction. Backfill material shall be compacted to the maximum dry density percentage specified in Table 629.15A and the in -place moisture content shall be not more than 2% above the optimum moisture content, as determined by AASHTO T 180, Method C .
