Pumps to be utilized in (2) independent systems -refer to Pump Staging Detail B(sheet 19)of drawings. Primary Pump(s):(2) PP1212S17 Floats and Alarms Backup pumpswill be setup on high level floats to ensure flow demands are met in the case that increased flow is encountered or the primary pump fails. SpillProtection/Prevention/Response All the discharge lines will be testedprior to starting, to identify leaks and all leaks corrected prior toputting the bypass into operation. Upon startup, after running the system for 2 hours all parts will betightened to ensure tightness. The city will be notified 48 hours prior to testing. Pumps will be placed on Spill Guards on site to prevent damage in case of spill. In the event of a majorbreak/spill, the pumps will be turned off immediately. A vacuum truck will be brought on site to initiate theclean-up process under the direction of the regulatory body having jurisdiction over this type ofspill. Periodic disposal of accumulated rainwater in containment berms is responsibility of contractor. This plan is written byUnited Rentals Pump Solutionsas general guidelines for the selection, installation andoperation of this bypass pumping system. It is thecontractor'sresponsibility to ensure adequatepumpingsystem, redundantpumping systems and proper equipment maintenance is available to divertthe completesewer flow preventing any spills or overflows.
