[1]
Editor's Note: See § A75-46, Pipe bedding and backfill materials.
C. 
General requirements for water mains.
(1) 
Particular care shall be taken not to injure the pipe coating. The interior of the pipe shall be thoroughly cleaned of foreign matter before being placed in the trench and shall be kept clean during placing operations by plugging or other approved method. The full strength of each section of pipe shall rest solidly upon the pipe bed, with recesses excavated to accommodate bells and joints. Any pipe that has the grade or joint disturbed after laying shall be taken up and relaid.
(2) 
Pipe shall not be laid in water or when trench or weather conditions are unsuitable for the work, except by permission of the Town Inspector. When work is not in progress, open ends of pipe and fittings shall be securely closed so that no trench water, earth or other substance will enter the pipe or fittings. Any section of pipe found to be defective before or after placing shall be replaced with sound pipe by the subdivider at his own expense. Fittings at bends in the pipeline shall be firmly wedged against the vertical face of the trench, with concreted thrust blocks to prevent the fittings from being blown from the lines when under pressure. Deflections from a straight line or grade, as required by vertical curves, horizontal curves or offsets, shall not exceed the maximum limits permissible in accordance with AWWA C 600. If the alignment requires deflections in excess of these limitations, special bends shall be furnished to provide angular deflections within the limit set forth. Except where necessary in making connections with other lines, or as authorized by the Town Inspector, pipe shall be laid with the bells facing the direction of laying.
A. 
After the pipe is laid, the joints completed and the trench partially backfilled leaving the joints exposed for examination, the newly laid piping or any valved section of piping shall, unless otherwise specified, be subjected for one hour to a hydrostatic pressure test of 50 pounds per square inch in excess of the anticipated static pressure at the points of reading when the system is put in operation. No piping installation will be accepted until or unless leakage (evaluated on a pressure basis of 150 pounds per square inch) is less than 34 United States gallons per 24 hours per mile of pipe per inch nominal diameter of pipe in twelve-foot lengths, 26 gallons for pipe in sixteen-foot lengths, and proportionately varied for other lengths of pipe. In calculating leakage, the Town Inspector may make allowance for added joints in the pipeline above the normal unit lengths of pipe. Defective material disclosed in the pressure test shall be replaced by the subdivider at his own expense with sound material, and the test shall be repeated until the test results are satisfactory to the Town Inspector.
B. 
The subdivider shall provide all test equipment and install necessary corporation stops for testing purposes, or at locations of dead-end lines for mechanically relieving entrapped air if no other air release device is available, at his own expense. Before placement of permanent paving, a measured leakage test of the entire pipeline may be required at the discretion of the Town Inspector. Leakage loss shall be within the allowances hereinbefore specified.
Each unit of completed supply line distribution system shall be sterilized with chlorine before acceptance for domestic operation. Sterilization shall be accomplished as described below or by the system prescribed by AWWA C 601 as determined by the Town Inspector. The amount of chlorine applied shall be such as to provide a dosage of not less than 50 parts per million. The chlorinating material shall be introduced to waterlines and distribution systems in a manner approved by the Town Inspector. If possible to do so, the lines shall be thoroughly flushed before introduction of the chlorinating materials. After a contact period of not less than eight and preferably 24 hours, the system shall be flushed with clean water until the residual chlorine content is not greater than 1.0 part per million. All valves in the lines being sterilized shall be opened and closed several times during the contact period. After flushing, samples of water shall be taken from each section of main and an analysis made to determine the purity of the water. Any section of main not meeting the standard for purity shall be re-chlorinated and tested until acceptable. The results of the tests shall be given to the Town Inspector. All costs for water tests will be paid for by the subscriber.
Booster pumping stations, storage facilities and other appurtenances to the distribution system shall be designed and constructed to afford a maximum of dependability and efficiency in operation and maintenance. Two copies of as-built drawings of these facilities, together with all manuals and descriptive data, shall be furnished to the Town Clerk before the facilities will be accepted by the Town.
A. 
A reproducible Mylar and two copies of the as-built water system showing the size and location of all pipes, valves, services, hydrants and miscellaneous appurtenances, together with ties, including elevations at street intersections and critical points throughout the system, all in accordance with good engineering practice, shall be furnished to the Town Clerk before the system will be accepted by the Town.
B. 
Water utility plan requirements shall be as follows:
(1) 
Sheet size: twenty-two by thirty-six (22 x 36) inches minimum.
(2) 
Scale: one inch equals 100 feet. If more than one sheet is required, a clearly drawn match line shall be shown on each sheet.
(3) 
Title block: name of subdivision; title: Water Utility Plan; date; name of subdivider; and licensed engineer or surveyor.
