CITY OF SANTA ANA <br />SPECIFICATIONS <br />PROJECT NO.: XX-XXXX <br />PROJECT TITLE <br /> <br />153 <br />6. Standby power generator size. <br />7. Method of protecting discharge manholes or structures from erosion and damage. <br />8. Thrust block sizes and restraining lengths of pipes and locations (if necessary). <br />9. Method of noise control for each pump and/or generator. <br />10. Any temporary pipe supports and anchoring requirements. <br />11. Design plans and computations for access to bypass pumping locations indicated <br />on the drawings. <br />12. Calculations for selection of bypass pumping pipe size. <br />13. Schedule for installation of and maintenance of bypass pumping piping. <br />14. Submit a sewer overflow emergency response plan. The plan will dictate backup <br />pumping plans, spill containment procedures, spill recovery procedures and <br />emergency call out phone numbers. <br />Provision shall be made by the Contractor for the collection of sewage from cutoff lateral <br />sewers. Lateral sewers shall be reconnected to the main before the termination of every <br />working day. <br />The text of Subsection 306-1.6 of the Standard Specifications is hereby deleted and <br />replaced with the following: <br />Pipe shall be measured along the longitudinal axis between the ends as laid and <br />shall include the actual pipe in place. <br />Following placement and compaction of backfill and prior to the placement of permanent <br />pavement, all newly constructed PVC sewer mains shall be cleaned and tested for <br />deflection and ovality by either using: a rigid mandrel for smaller diameter pipe; or laser <br />profile technology and/or with an electronic deflect-o-meter for larger diameter piping. <br />The deflection and or ovality shall not exceed (5%) of the inside diameter of the pipe. If <br />the pipe exceeds this tolerance, it is the responsibility of the contractor to replace and re- <br />test the newly constructed pipe for deflection and ovality. <br />If the pipe is to be tested by mandrel, the rigid mandrel shall have a circular cross section <br />having a diameter of at least 95 percent of the specified inside pipe diameter and shall be <br />pulled through the pipe by hand. The minimum length of the circular portion of the <br />mandrel shall be equal to the nominal diameter of the pipe. A ¼-inch diameter nylon line <br />shall be pulled from manhole to manhole and shall be left for use in conducting t he <br />CCTV inspection. Obstructions encountered by the mandrel shall be repaired and the <br />pipeline section shall be retested. <br />505 E Central Ave <br />#B11/6/2024
