2.2 The water main shall be laid and maintained to the required lines and grades, with fittings, valves and hydrants at the required locations. Spigots shall be centered in bells and all hydrant stems plumb.
2.3 All water mains shall be laid at a sufficient depth to allow for a minimum cover of 42 inches below finished grade. The depth shall be measured as shown on the typical drawings. Where future changes in grade are contemplated, the depth shall be increased or decreased on the instruction of the manager.
2.4
The trench shall be dug so that the pipe can be laid to
the alignment and depth required, and it shall be excavated only so far in
advance of the pipe laying safety and traffic requirements permit. The trench shall be so braced and
drained that the workmen may work therein safely and efficiently. The discharge of the trench dewatering
shall be conducted to natural drainage channels, or drains with sedimentation
controls provided as may be required by
2.5 The width of the trench at the bottom shall be sufficient to permit the pipe to be laid and jointed properly and backfill to be placed and compacted properly. The trenches shall be of such extra width, when required, as will permit the convenient placing of timber supports, sheeting and bracing, and handling of special equipment or materials.
2.6
2.7 The trench shall be excavated to the depth required to provide a uniform and continuous bearing for the pipe on solid ground between bell holes, except that it will be permissible to disturb the bottom of the trench near the middle of each length of pipe for the withdrawal of pipe slings or other tackle. Any part of the bottom of the trench below the specified grade shall be corrected with approved material, thoroughly compacted. The subgrade shall be finished with hand tools, or the Developer may over-excavate and place and compact granular fill.
2.8 Proper equipment, tools and facilities shall be used by the Developer for the safe and efficient prosecution of the work. All pipe, fittings, valves, and hydrants shall be carefully lowered into the trench piece by piece with a derrick, ropes or other suitable tools or equipment, so as to prevent damage. In no circumstances shall water main materials be dropped or dumped into a trench.
2.9 The interior of all pipes shall be inspected before being laid in the trench and any foreign matter removed from it by swabbing. If the pipe-laying crew cannot lay the pipe without getting earth into it the Manager may required that a tightly woven canvas bag of suitable size be placed over each end of the pip and left there until the connection is to be made to the adjoining pipe.
2.10 The amount of pipe deflection at joints and couplings shall not exceed that recommended by the manufacturer. Copies of the pipe manufacturer specifications will be on hand at the time the pipe is being laid.
2.11
When pipe is not being laid, the open ends of pipe
already in place shall be closed to prevent trench water from entering the
line. This provision shall apply
during the
2.12 Whenever water is excluded from a pipe, adequate backfill shall be placed on the pipe to prevent it from floating. Any pipe which has floated shall be removed from the trench and be re-laid.
2.13 Bedding for pipe and all backfill shall be sand or 5/8-minus gravel. Bedding shall be deposited uniformly by and in the trench to completely surround the pipe without voids on both sides for the full width of the trench and to the mid-diameter of the pipe.
2.14 Thrust blocks shall be installed where required in accordance with the Standard Plan.
3.
DUCTILE IRON PIPE
3.1 Ductile-iron shall be handled so that the coating and lining is not damaged. If any part of the coating or lining is damaged, the repair shall be made by the Developer at his expense to the satisfaction of the Manager.

3.3 After placing a length of pipe in trench, the spigot end shall be centered in the bell of the adjoining pipe and the pipe forced home and brought into correct line and grade. The pipe shall be secured with approved backfill material tamped under it except at the bell end. Pipe and fittings which do not permit sufficient and uniform space for joints shall be removed and replaced with pipe and fittings of proper dimensions to ensure such uniform space. Precautions shall be taken to prevent dirt from entering the joint space.
3.4 The cutting of pipe for inserting valves, fittings or closure pieces shall be done in a neat and workmanlike manner without damage to the pipe or cement linings and so as to leave the end smooth and at right angles to the axis of the pipe. The cutting of pipe with an oxyacetylene torch shall not be allowed.
3.5 Pipe shall be laid with bell ends facing in the direction of laying unless otherwise directed by the Manager.
3.6 Whenever it is necessary to deflect pipe from a straight line to avoid obstructions or to plumb valve stems, or where long-radius curves are permitted, the amount of deflection shall not exceed the manufacturer’s recommendations. Where necessary, short lengths shall be used.
3.7 If mechanical joints are used, the rubber gaskets, glands and bolt shall be installed in accordance with the manufacturer’s instructions. Care shall be taken to avoid exposure of rubber gaskets to direct sunlight for excessive periods of time. The gaskets shall be stored in a clean, cool place, protected from sunlight and contamination until ready for installation on the pipe.
3.8 Bedding and backfill material shall be sand or 5/8-inch minus gravel. Bedding shall be deposited uniformly by hand in the trench to completely surround the pipe without voids on both sides for the full width of the trench and to the mid-diameter of the pipe.

4.1 Valves, fittings, plugs, and caps shall be set and jointed to the pipe in the manner heretofore specified for cleaning, laying, and jointing pipe.
4.2 A valve box and concrete market post shall be provided for every valve. The valve box shall not transmit shock or strain to the valve and shall be centered plumb over the key nut of the valve per Standard Drawing No 103 Valve Box and Extensions. The box cover shall be flushed with the surface of the finished grade or at such other level as may be directed. Market post shall be painted yellow.
4.3 All dead ends on mains shall be closed with cast iron plugs, caps, blow-off valves, or hydrants.
4.4 Thrust blocking shall be applied at tees, plugs, caps, and bends, and where changes in pipe diameter occur at reducers or in fittings. The size and shape of thrust blocking are shown on typical drawings.
4.5 Thrust blocking shall be of concrete of a mix not leaner than 1 part cement, 2 ½ parts sand, and 5 parts aggregate, having compressive strength of not less than 2,000 psi in 24 hours when using high early strength cement, and 7 days when using standard cement. Blocking shall be placed between solid ground and the fitting to be anchored.
4.6 Metal harness of tie rods and pipe clamps shall be used with ring-type couplings to prevent movement when specifically directed by the Engineer. Steel rods and clamps shall be galvanized or otherwise rust-proof.
4.7 Hydrants shall be located in a manner to provide complete accessibility, and also that the possibility of damage from vehicles or injury to pedestrians will be minimized. Pumper nozzles shall face the traveled roadway and hydrant barrels shall be rotated if necessary to achieve this position.
4.8 Should hydrant extension be required, the Developer will be directed to install same at time of construction.
4.9 Each hydrant shall be connected to the main with a 6-inch branch controlled by an independent 6-inch gate valve as shown on the Standard Drawing No 101 Fire Hydrant Assembly.
4.10 Hydrant drainage shall be provided at the base of the hydrant by placing coarse gravel or crushed stone mixed with coarse sand as shown on the Standard Drawing No 101 Fire Hydrant Assembly.
4.11 If the groundwater table is higher than the hydrant drain, or where otherwise required by the Engineer, the Developer shall plug the hydrant drain. No gravel will then be placed around the drain holes.
5. TESTING AND DISINFECTION
5.1 A hydrostatic leakage test shall be conducted after all newly constructed water mains, fire lines, fire hydrants, leads and stubouts have been completely installed and backfilled.
The duration of each leakage test shall be one hour, and the test sections will be subjected to the hydrostatic pressure of 200 psi based on the elevation of the lowest point in the section under test and corrected to the elevation of the test gauge, EXCEPT, no section shall be tested at less than 100 psi.
Leakage is defined as the quantity of water which must be added to the tests section to maintain the specified test pressure after the pipe has been filled with water and the air expelled. Hydrostatic leakage test will be in accordance with DOT/APWA Section 7-11, 3(11) or AWWA C-600 specifications, unless specified otherwise by the Association.
The Developer shall furnish all necessary apparatus and labor to conduct the test.
5.2 No pipe installation will be accepted until the leakage is not greater than the number of gallons per hour as determined by the following table:
Leakage Allowance
Gallons per 100 joints per hour
Pipe Diameter Test Pressure (psi)
(inches) 100 125 150 200 225
3 0.41 0.45 0.50 0.57 061
4 0.54 0.60 0.66 0.76 0.81
6 0.81 0.91 0.99 1.15 1.22
8 1.08 1.21 1.32 1.53 1.62
10 1.35 1.51 1.66 1.91 2.03
12 1.62 1.81 1.99 2.29 2.43
14 1.89 2.12 2.32 2.68 2.82
Evaluated on the basis of 200 psi this leakage is approximately equal to 3.4 gallons per mile of pipe in one hour, for 6-inch-diameter pipe in 18-foot lengths. For 8-inch pipe, the allowance is 4.5 gallons per mile.
Should any test disclose leakage greater than that specified above, the Developer shall, at his own expense, locate, repair, and retest the defective section.
5.3 Each test section of pipe shall be slowly filled with water, and the specified test pressure shall be applied by means of a pump connected to the pipe. The pump, pipe connection, and all necessary apparatus and labor for the test shall be furnished by the Developer.
5.4 Before applying the leakage test pressure, all air shall be expelled from the pipe. If hydrants or blow-offs are not available at high places, the Developer shall make the necessary taps at point of highest elevation before the test is made and insert plugs after the test has been completed.
5.5 Upon completion of the leakage tests, the entire extension and appurtenances shall be disinfected. After a proper set time, all pipe, reservoirs and appurtenances shall be flushed.
Disinfection methods shall comply with Washington State Department of Health standards, as well as American Water Works Association current standards, which are presently as shown below:
AWWA C-651-86
AWWA C652-8C
5.6 The one-year maintenance period shall not commence until after the conclusion of satisfactory leakage and disinfection tests and a Notice of Acceptance have been received. The one-year maintenance period will commence from the date of the Notice of Acceptance.
