The full length 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.
(b) 
Pipe shall not be laid in water or when trench or weather conditions are unsuitable for the work, except by permission of the Village inspector. When work is not in progress, the 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 concrete 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 connection with other lines or as authorized by the Village inspector, pipe shall be laid with the bells facing the direction of laying.
G. 
Tests for water mains.
(1) 
After the pipe is laid and the trench backfilled, the newly laid piping or any valved section of piping shall, unless otherwise specified, be subject 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 of 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 Village inspector may make allowance for added joints in the pipeline above the normal for unit length 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 Village inspector.
(2) 
The subdivider shall provide all test equipment and install necessary corporation stops for testing purposes, or at locations of deadened 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 Village inspector. Leakage loss shall be within the allowances hereinbefore specified.
H. 
Sterilization. Each unit of completed supply line and distribution systems 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 Village 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 the waterlines and distribution systems in a manner approved by the Village 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 the main and an analysis made to determine the purity of the water. Any section of the main not meeting the standard for purity shall be rechlorinated and tested until acceptable. The results of the tests shall be given to the Village inspector. All costs for water tests will be paid for by the subdivider.
I. 
Appurtenances. 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.

(2) 
Sanitary sewer systems shall be designed on the basis of an average daily per capita flow of sewage of not less than 100 gallons per day. Lateral sewers shall be designed to carry a peak flow of 400 gallons per capita per day. Trunk sewers shall be designed to carry a peak flow of 250 gallons per capita per day.

No sanitary sewer shall be less than eight inches in diameter. All sanitary sewers shall be designed and constructed to give minimal velocities, when flowing full, of not less than 2.0 feet per second, based on Kitter's formula using an "n" value of 0.013. Where velocities greater than 15 feet per second are attained, special provisions shall be made to protect against displacement by erosion and shock.

(4) 
The entire sewer line shall be tested by the exfiltration test or the low-pressure air method.
(a) 
Exfiltration test. Tests shall be made by filling the sewer with water and measuring the quantity of leakage from the sewer. The head of water during the tests shall be maintained at least two feet above the highest section of the work being tested or at least two feet above the elevation of the groundwater, whichever is greater. The line shall remain filled for at least 24 hours to allow absorption. After this period, makeup water shall be added to bring the water level to the elevation specified above. The test shall be conducted for 24 hours. The allowable leakage per 24 hours per inch of diameter per 1,000 feet of sewer tested shall not exceed 30 gallons.

Low-pressure air method.
[1] 
All branch fittings shall be securely plugged to withstand the internal test pressures. The section of line being tested shall also be securely plugged at each manhole. All stoppers shall be adequately braced when required.
[2] 
Air shall be slowly supplied to the plugged pipeline until the internal air pressure reaches 4.0 pounds per square inch greater than the average back pressure of any groundwater that may submerge the pipe. At least two minutes shall be allowed for temperature stabilization before proceeding further.
[3] 
The pressure shall then be allowed to decrease 3.5 pounds per square inch, at which time a stopwatch shall be started. At the end of the holding time on the Table for Sanitary Sewer Low-Pressure Air Test shown in the Standard Detail Drawings,[3] the pressure drop shall be recorded. The pipeline shall be considered acceptable if the pressure has not dropped below 2.5 pounds per square inch.

After the subgrade has been accepted by the Village Supervisor of Public Works, a twelve-inch gravel subbase course shall be constructed. The course shall be built in two six-inch compacted layers. Compaction shall be accomplished in the same manner described for the preparation of subgrade until thoroughly compacted and true to grade and cross section. The finished subbase surface must be completed with a ten-ton smooth steel wheel roller to the satisfaction of the Village Supervisor of Public Works. The subbase shall then be primed with 0.3 gallon per square yard of New York State Department of Transportation cationic asphalt emulsion material 702-4101, then chipped lightly and rolled.
