(4) Installation.
(a) Pipe and fittings shall be installed in the conditions outlined on the detailed contract drawings. When pipe cover material is specified, this material shall be tamped around and under the full barrel of the pipe. Unless otherwise specified on the drawings, minimum cover over the top of the pipe or fittings shall be five feet. During installation, the contractor shall prevent the entrance of all foreign material (such as dirt, water and stones) into the pipe.
(b) On ductile iron pipe two serrated silicon bronze wedges shall be inserted in the bell, 180° apart at three o'clock and nine o'clock. Thrust blocking shall be installed at all elbows, tees, hydrants, plugs and caps with dimensions specified on the detailed drawings. Concrete blocking shall be poured against undisturbed soil. Steel tie-rod (3/4 inches in diameter) restraining hardware shall be used at fittings and valve clusters as shown on the contract drawings.
(c) Copper water service pipe shall be installed under all roadways by a trenchless method. The trenchless method shall be accomplished by the use of a soil-displacement-type hammer. The boring tool shall provide an open hole of adequate diameter to allow itself to successfully pull through a 3 inch I.P.S., DR 17, PE 3408 polyethylene pipe casing. Copper water service pipe shall be installed in the casing without filling of the annular space.
(d) The location and limits of the excavated pits for the launching and receiving of the boring tool shall be marked out by the Engineer. Excavations shall be sheeted and braced in accordance with the technical specifications of this contract. Where copper service piping is installed by open-cut excavation, the pipe shall be bedded and covered with approved granular material with a maximum particle size of two inches, as shown on the detailed drawings.
(5) Cleaning water mains. After the completion of the water main installation, all mains will be flushed with water to remove all dirt and stones which may have entered during construction. Pipes shall be flushed until the water runs clear.
(6) Disinfection of water mains.
(a) All water mains shall be disinfected in accordance with ANSI/AWWA Specification C601-B1-a, a copy of which can be furnished by the owner/engineer to the contractor upon his request.
(b) After the main has been disinfected and flushed, three samples of water shall be tested for total coliform in a New York State Department of Health approved laboratory. If drinking water standards are not met, the disinfection procedure shall be repeated at no extra cost to the owner.
C. Hydrostatic testing of water mains. After backfilling, all pipe shall be subjected to a pressure test and a leakage test in accordance with AWWA Spec. C600, Section 4, as follows:
(1) Pressure test. After the pipe has been laid, all newly laid pipe or any valved section thereof shall be subjected to a hydrostatic pressure of at least 1.5 times the working pressure at the point of testing.
(2) Test pressure restrictions. Test pressures shall:
(a) Not be less than 1.25 times the working pressure at the highest point along the test section.
(b) Not exceed pipe or thrust-restraint design pressures.
(c) Be of at least two-hour duration.
(d) Not vary by more than + or - 5 psi (0.35 Bar) for the duration of the test.
(e) Not exceed twice the rated pressure of the valves or hydrants when the pressure boundary of the test section includes closed gate valves or hydrants.
| NOTE: Valves shall not be operated in either direction at differential pressure exceeding the rated pressure. |
(f) Not exceed the rated pressure of the valves when the pressure boundary of the test section includes closed, resilient-seated gate valves or butterfly valves.
(3) Pressurization. Each valved section of pipe shall be filled with water slowly, and the specified test pressure, based on the elevation of the lowest point of the line or section under test and corrected to the elevation of the test gauge, shall be applied by means of a pump connected to the pipe in a manner satisfactory to the owner. Valves shall not be operated in either the opening or closing direction at differential pressures above the rated pressure. It is good practice to allow the system to stabilize at the test pressure before conducting the leakage test.
(4) Air removal. Before applying the specified test pressure, air shall be expelled completely from the pipe, valves and hydrants. If permanent air vents are not located at all high points, the contractor shall install corporation cocks at such points so that the air can be expelled as the line is filled with water. After all the air has been expelled, the corporation cocks shall be closed and the test pressure applied. At the conclusion of the pressure test, the corporation cocks shall be removed and plugged, or left in place at the discretion of the owner.
(5) Examination. Any exposed pipe, fittings, valves, hydrants and joints shall be examined carefully during the test. Any damage or defective pipe, fittings, valves or hydrants that are discovered following the pressure test shall be repaired or replaced with sound material, and the test shall be repeated until it is satisfactory to the owner.
D. Mains.
(1) All mains, fittings, valves, hydrants shall have a minimum earth cover of 5.0 feet. All mains shall be installed on a uniform grade and at an elevation to conform to the connecting mains. Mains shall be interconnected where possible and dead ends, if unavoidable, shall not exceed 600 linear feet in length and be provided with a hydrant at the end.
(2) Mains shall be installed on a bed of selected earth free from stones or in a bed of sand or fine crushed gravel, to provide uniform support the length of the pipe. All backfill around the pipes and for a height of 12 inches above the pipe shall be firmly tamped in place. The remainder of the trench may be tamped in layers or rolled and machine-tamped in place. Pipes shall not be embedded in clay or vegetable matter or similar materials.
E. All tees, fittings, plugs, pipe ends and hydrants shall be firmly supported by concrete thrust blocks of sufficient size to prevent separation of the joints or to prevent the pipe from shifting out of alignment. Size of thrust blocks shall be calculated by standard engineering design methods. All installed brass fittings that come in contact with potable water shall not be composed of lead.
[Amended 8-5-2020 by L.L. No. 2-2020]
F. Service pipes shall conform to ASTM B-88 Type K copper water tube. An eight-inch-radius loop shall be provided in the pipe at the connection of the service pipe to the main to provide flexibility. All service pipes shall have a brass corporation stop inserted in the main, a brass inverted key curb stop and drain with C.I. curb box at the right-of-way line and a brass ground key meter top and drain at the point where the service line ends and the meter is installed.
G. Leakage tests.
(1) The leakage test shall be conducted concurrently with the pressure test.
(2) Definition. "Leakage" shall be defined as the quantity of water that must be supplied into the newly laid pipe, or any valved section thereof, to maintain pressure within five pounds per square inch (0.35 Bar) of the specified test pressure after the air in the pipeline has been expelled and the pipe has been filled with water. Leakage shall not be measured by a drop in pressure in a test section over a period of time.
(3) Allowable leakage.
(a) No pipe installation will be accepted if the leakage is greater than that determined by the following formula:
| Where: |
| | L = | The allowable leakage, in gallons per hour |
| | S = | The length of pipe tested, in feet |
| | D = | The nominal diameter of the pipe, in inches. |
| | P = | The average test pressure during the leakage test, in pounds per square inch gauge. |
(b) These formulas are based on an allowable leakage of 11.65 gallons per day, per mile, per inch nominal diameter at a pressure of 150 pounds per square inch. When testing against closed metal-seated valves, an additional leakage per closed valve of 0.0078 gal/h/mm) of nominal valve size shall be allowed. When hydrants are in the test section, the test shall be made against the closed hydrant.
(4) Acceptance of installation. Acceptance shall be determined on the basis of allowable leakage. If any test of pipe laid discloses leakage greater than that specified above, the contractor shall, at his own expense, locate and make repairs as necessary until the leakage is within the specified allowance. All visible leaks are to be repaired regardless of the amount of leakage.
(5) The tests shall be observed and approved by the Town Water Superintendent before acceptance and connection of the mains to the Water District system.
H. Disinfection.
(1) The system shall be disinfected and sterilized and be satisfactory in all respects to the Departments of Health of the State of New York and Cortland County and all water departments supplying water to the Water District. Samples shall be submitted as required by such agencies and written approval shall be submitted as proof of satisfactory disinfection. In addition to the foregoing, the treated water shall produce a residual of 10 parts per million of chlorine after a twenty-four-hour retention period.
(2) The disinfection of the system shall not take place until just prior to connection of the system to the Water District or mains. Samples of the water in the main shall be taken over a full two days and tested and approved.
(3) Reverse flow of water being treated in the mains shall be prevented from flowing into the lines supplying the water. After chlorination, the water in the mains being treated shall be flushed from the mains at its extremities until the replacement water tests are equal chemically and bacteriologically to those of the permanent approved supply.
I. All water mains, fittings, valves and fire hydrants shall have a minimum cover of five feet but not less that six inches in diameter.
