All gravity sanitary sewers or extensions to sanitary sewers, including manholes, shall satisfy requirements of a final infiltration test before they will be approved and wastewater flow permitted by the Chief Operator. The infiltration rate shall not exceed 25 gallons per 24 hours per mile per nominal diameter in inches. An exfiltration test may be substituted for the infiltration test; the same rate shall not be exceeded. The exfiltration test shall be performed by the applicant, under the supervision of the Chief Operator, who shall have the responsibility for making proper and accurate measurements required. The exfiltration test consists of filling the pipe with water to provide a head of at least five feet above the top of the pipe or five feet above groundwater, whichever is higher, at the highest point under test, and then measuring the loss of water, from the pipe section under test, by the amount of water which must be added to maintain the original level. In this test, the test section must remain filled with water for at least 24 hours prior to taking any measurements. Exfiltration shall be measured by the drop of water level in a standpipe with a closed bottom end or in one of the sewer manholes serving the test section. When a standpipe and plug arrangement is used in the upper manhole in the test section, there shall be some positive method for releasing entrapped air prior to taking any measurements.
The test section shall be as ordered or as approved, but in no event longer than 1,000 feet. In the case of sewers laid on steep grades, the test length may be limited by the maximum allowable internal pressure on the pipe and joints at the lower end of the test section. For purposes of determining the leakage rate of the test section, manholes shall be considered as sections of forty-eight-inch diameter pipe, five feet long. The maximum allowable leakage rate for such a section is 1.1 gallons per 24 hours. If leakage exceeds the allowable rate, then necessary repairs or replacements shall be made and the section retested.
The test period, during which the test measurements are taken, shall not be less than two hours.
Prior to testing, the section shall be lamped. Any "joint" out of straight alignment shall be realigned.
Also prior to testing, all plastic pipes in the test section shall be tested for deflection. Deflection testing shall involve the pulling of a ball, whose diameter is 95% of the pipe inside diameter, through the pipe. Any "joint" with a deflection greater than 5% shall be replaced. The test section shall be flushed just prior to deflection testing.
A. 
In lieu of hydrostatic testing (exfiltration or infiltration) for gravity sewers, air testing may be employed with the approval of the Chief Operator. Low-pressure air tests shall conform to ASTM Specification C 828. All sections to be tested shall be cleaned and flushed and shall have been backfilled prior to testing. The air test shall be based on the time, measured in seconds, for the air pressure to drop from 3.5 PSI to 2.5 PSI. Acceptance is based on limits stated in ASTM Specification C 828. Before pressure is applied to the line, all connections shall be firmly plugged. Before the test period starts, the air shall be given sufficient time to cool to ambient temperature in the test section.
B. 
If the test section is below groundwater, the test pressure shall be increased an amount sufficient to compensate for groundwater hydrostatic pressure; however, the test pressure shall not exceed 10 psi.
C. 
The test gauge shall have been recently calibrated, and a copy of the calibration results shall be made available to the Chief Operator prior to testing.
All sanitary sewers and extensions to sanitary sewers constructed at the owner's expense, after final approval and acceptance by the Chief Operator and concurrence by the Town of Cazenovia Town Board, respectively, shall become the property of the Town of Cazenovia and shall thereafter be operated and maintained by the Town. Said sewers, after their acceptance by the Town, shall be guaranteed against defects in materials or workmanship for one year by the owner. The guarantee shall be in such form and contain such provisions as deemed necessary by the Town, secured by a surety bond or such other security as the Town Board may approve.
A. 
All contractors engaged in connecting building laterals with sanitary sewers, who perform any work within the right-of-way of any highway, shall file a bond, letter of credit or cash equivalent in the amount of $10,000, or such amount as set by the Chief Operator, with the Town Clerk to indemnify the Town, its employees, servants, agents, etc., against loss, cost, damage or expense sustained or recovered on account of any negligence, omission or act of the applicant for such a permit, or any of his, their or its servants or agents, arising or resulting directly or indirectly by reason of such permit or consent or of any act, construction or excavation done, made or permitted under authority of such permit or consent. All bonds shall contain a clause that permits given by the Codes Enforcement Officer and/or Chief Operator may be revoked at any time for just cause.
B.
