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.

629

6-119The 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.

629.06BEDDING 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.

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

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.

629

6-120The 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 position. 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 closed 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.

629.08JOINING PIPE . Water pipe shall be joined in accordance with the detailed instructions 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.

629 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 permit 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 repaired

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 manufacturer

of the valve and being careful to avoid all damage to surfaces and coatings.

629.10SETTING 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.

629

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 between 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 to, 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 the 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 dry-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.

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

end of the trench with stone 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 provided 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 on 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

otherwise rust proofed, or shall be painted as shown in the Plans or directed by the Engineer.

629

629.12PRESSURE 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 completing 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 pounds 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 completed. 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 shall 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 the 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.

629.13DISINFECTING. Before being placed in service, 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 of

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 dosages 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.

629

Within 24 hours following 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. Following 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 testing.

Passing sample results are required before the system may be placed on line for drinking. Sample bottles

shall be obtained from the same laboratory.

629.14HOUSE CONNECTIONS. Service lines disrupted within the project limits shall be repaired or

replaced as ordered by the Engineer. The actual location of each ordered house connection shall be

tubing shall be attached to the corporation stop and curb stop in a manner satisfactory to the Engineer.

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 by 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.

629

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 as 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 shall 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 connections.

from borrow, and when compacted shall make a dense stable fill. The material shall not contain

vegetation, porous matter, 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 conform 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 when 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 necessary to

obtain proper compaction.

Backfill material shall be compacted to the maximum dry density percentage specified in Table
