SECTION 4 – SANITARY <br />69 <br />slightly. Additional test liquid will be required to maintain pressure. The water added during <br />this phase will not be monitored. <br />Testing: Immediately following the initial expansion phase, monitor the amount of make-up <br />water required to maintain test pressure for two (2) hours. The test pressure shall be measured <br />at the lowest possible point in the section being tested. The amount of make-up water required <br />shall not exceed the allowance shown in Table 2, Technical Note 802. <br />Lines or joints, which leak, shall be repaired and retested. All pipes, fittings , and other <br />materials found to be defective under test shall be removed and replaced by the Contractor at <br />their own expense. <br />Depressurizing: At the conclusion of the test, slowly and carefully depressurize the test section <br />by the controlled release of the test liquid. <br />4-4.2 (f) FORCE MAIN TRACER WIRE <br />Testing for conductivity shall be performed on each section of tracer wire, immediately following <br />installation and prior to final project acceptance. <br />4-4.2 (g) MANHOLE NEGATIVE AIR PRESSURE (VACUUM) TEST <br />Manholes shall be air tested in accordance with ASTM C1244-93, Standard Test Method for <br />Concrete Sewer Manholes by the Negative Air Pressure (Vacuum) Test. <br />4-4.2 (h) SEWER TELEVISING <br />1.) Before final acceptance, the gravity sanitary sewer system shall be flushed as required and <br />televised. <br />2.) Provide television equipment capable of properly documenting the conditions as found within <br />the pipe in a digital video format (DVD). Lighting for the camera shall illuminate the entire <br />periphery of the sewer. The camera shall be radial view type capable of viewing 360 degrees <br />within the pipe and shall provide an unobstructed view of the full pipe. <br />3.) The video inspection shall begin with a clear identification of the televising location, upstream <br />and downstream manhole designation, and pipe diameter. The DVDs shall provide an accurate <br />length measurement of the entire segment and of the distance to each lateral connection. Pan <br />all lateral connections. <br />4.) Televising DVDs shall be submitted to the City Engineer for review and approval. The DVDs <br />shall be clearly and properly labeled. Inspection for individual sewer segments (manhole to <br />manhole) shall be bookmarked. <br />4-4.2 (i) CIPP TESTING <br />1.) The City Engineer shall be advised forty-eight (48) hours prior to conducting quality assurance <br />tests.
