CITY OF SANTA ANA APPENDIX I PROJECT NO.: XX-XXXX PROJECT TITLE 2. Number, size, material, location and method of installation of suction piping. 3. Number, size, material, location and method of installation of discharge piping. 4. Bypass pump sizes, capacity, number of each size to be on -site and power requirements. 5. Calculations of static lift, friction losses, and flow velocity (pump curves showing pump operating range shall be submitted). 6. Standby power generator size. 7. Method of protecting discharge manholes or structures from erosion and damage. 8. Thrust block sizes and restraining lengths of pipes and locations (if necessary). 9. Method of noise control for each pump and/or generator. 10. Any temporary pipe supports and anchoring requirements. 11. Design plans and computations for access to bypass pumping locations indicated on the drawings. 12. Calculations for selection of bypass pumping pipe size. 13. Schedule for installation of and maintenance of bypass pumping piping. 14. Submit a sewer overflow emergency response plan. The plan will dictate backup pumping plans, spill containment procedures, spill recovery procedures and emergency call out phone numbers. Provision shall be made by the Contractor for the collection of sewage from cutoff lateral sewers. Lateral sewers shall be reconnected to the main before the termination of every working day. The text of Subsection 306-1.6 of the Standard Specifications is hereby deleted and replaced with the following: Pipe shall be measured along the longitudinal axis between the ends as laid and shall include the actual pipe in place. Following placement and compaction of backfill and prior to the placement of permanent pavement, all newly constructed PVC sewer mains shall be cleaned and tested for deflection and ovality by either using: a rigid mandrel for smaller diameter pipe; or laser profile technology and/or with an electronic deflect-o-meter for larger diameter piping. The deflection and or ovality shall not exceed (5%) of the inside diameter of the pipe. If the pipe exceeds this tolerance, it is the responsibility of the contractor to replace and re- test the newly constructed pipe for deflection and ovality.
