In particular, those trencher or excavations which are within fifteen (15) feet of the edge of pavements or the edge of traveled roadways, shall be kept filled up to the same level as the adjacent undisturbed ground. Any settlement which occurs during this period shall be immediately filled in to prevent the possibility of accidents.
1.17 WATER MAIN TESTING
Disinfection - All new waterlines shall be disinfected in accordance with procedures outlined in AWWA C651. As previously specified, all pipe interiors shall be cleaned before laying and shall be kept clean thereafter. Chlorination may be accomplished by the continuous feed method or the slug method.
After a main has been completed, it shall be filled with the portable water from the public supply while exhausting air from the other end and at intermediate places along the main, i.e., at the fire hydrants and corporation stops installed at the extremities of the main for this purpose. After filling, the residual chlorine strength of the solution of clean water and chlorine in the main shall be determined. All filling operations must be conducted under the supervision of the Project Inspector.
Sterilization can be accomplished with a solution of clean water and chlorine having a residual strength of 50ppm. The solution shall be tested at the extremities of the main and at the intermediate points to make sure the solution has the required strength. If the solution in the main contains less than 50ppm chlorine, a solution of clean water and chlorine having residual strength of 50ppm shall be pumped into the main from a cleaned and sterilized container, while exhausting the existing solution shall remain in the main for at least 12 hours to assure complete sterilization.
During the sterilizing process, the main shall be isolated from existing adjacent mains and extreme care shall be used to prevent the pressure in the main from rising about 20 psi. This low pressure is to prevent and possibility of highly chlorinated water from entering adjacent water mains which are in service. After the main has been filled with the chlorine solution, the existing solution, until a chlorine residual of 50 ppm is obtained throughout the main.
After sterilizing the main, it shall be thoroughly flushed with potable water from the public supply until the water in the main has approximately the same chlorine content as water in the existing mains. Bacteriological samples shall not be taken for testing until the main has been tested for leakage.
When the water runs clear, shut off the main and let the water remain in the pipe for at least three (3) days. At the end of at least three (3) days, flush out the entire contents of the main. Care shall be taken during this operation to completely remove the old water from the main. After this is done, shut off the main and let water remain in the pipe for 24 hours. After 24 hours, an employee of the Village of Wakeman will test the water for a determination of the alkalinity and pH. In case the alkalinity and pH are not satisfactory, the main shall be flushed again to remove the old water. After this is done, shut off the main and let the water remain in the pipe for at least four (4) hours. At the end of at least four (4) hours, repeat until the alkalinity and pH are approved by the Village of Wakeman.
In all cases, tests for chlorine content shall be in accordance with DPD test in APHA Standard Methods, 16th Edition, (1985).
The Contractor shall furnish all materials, corporation stops, labor and equipment required to sterilize the main.
1.18 PRESSURE AND LEAKAGE TESTS
All new waterlines shall be pressure and leakage tested in accordance with procedures outlined in AWWA C600-87. When a main has been sterilized and flushed, a leakage test shall be applied to it The main shall remain isolated from adjacent mains and a pressure of at least 150 pounds per square inch shall be applied by pumping clean water containing 10 ppm chlorine from a cleaned and sterilized container through" a 1 inch corporation stop installed in the ends of the main, with the Contractor to provide an initial pressure of 150-160 psi.
The pressure test shall be started in an afternoon and the pressure shall be on for 18 hours and then the pressure shall be maintained at 150 psi or more for an additional 6 hours by pumping water from the container. A minimum test pressure of the 6 hours period the water shall be measured and the loss by leakage shall not exceed that as determined by the formula:
L= S x D x (P)½
in which the L is the allowable leakage in gallons per hour; S is the length in feet of main line being tested; D is the nominal diameter of the pipe in inches; and P is the average test during the leakage test in pounds per square inch gage.
When Hydrants are in the test section the test shall be made against the closed hydrant.
Pressure testing of each side of the intermediate valves shall be done at this time by shutting each valve and exhausting the pressure on one side and then applying the test pressure of 150 psi or more to the main on the opposite side of the valve. This procedure shall be repeated for each intermediate valve.
If the main valves do not pass leakage test the leak or leaks shall be located and repaired and the testing procedure repeated.
Upon completion of the leakage tests, the main shall be thoroughly flushed with potable water from the public supply until water in the main has approximately the same chlorine content as water in the existing main.
The Contractor shall furnish all materials, labor and equipment for testing.
1.19 BACTERIOLOGICAL TESTS
After a water main has been sterilized and tested for leakage, bacteriological samples shall be collected from the extremities and intermediate points along the main by an employee of the Village of Wakeman experienced in the taking of water samples. Bacteriological samples shall not be taken by the Contractor.
If results of two consecutive sets of bacteriological tests show the water to be safe, the main may be placed in service. If bacteriological results show the water to be unsafe the main shall be completely sterilized and retested again. Sterilizing of the main is the responsibility of the Contractor who shall provide all necessary materials and labor and the main will not be placed in service and accepted until the bacterial quality of water has been approved by the Village of Wakeman. The Village of Wakeman will perform two sets of bacteriological tests at no charge to the Contractor. Additional tests will be at the expense of the Contractor.
After the bacteriological tests are satisfactory, a representative of the Village of Wakeman will open all valves to place the line in service.
