BACKGROUND
The Orange County Sanitation District (OC San) operates 15 pump stations within its regional collection system. The pump stations lift wastewater from low points where a gravity flow system cannot be used and convey wastewater to the treatment plants.
The pumps in these stations require routine removal and restoration activities to maintain design capacity and reliability. These pump stations are critical to the collection system operation and, in the event of the loss of pumping capacity, may result in a backup or sewer spill.
RELEVANT STANDARDS
Achieve less than 2.1 sewer spills per 100 miles
Commitment to safety & reducing risk in all operations
Protect OC San assets
PROBLEM
One Main Sewage Pump (MSP) at the Bitter Point Pump Station requires removal from service. OC San will install the available spare pump to maintain the station’s pumping capacity and operational redundancy. The removed pump must then be repaired and overhauled to restore it to serviceable condition and replenish OC San’s spare-pump capability for future maintenance needs or equipment failures.
PROPOSED SOLUTION
Approve a Sole Source Purchase Order to Flo-Services, Inc. to repair and overhaul the removed MSP. Upon completion, the pump will be returned to OC San’s spare-pump inventory, restoring the availability of a serviceable spare for future planned maintenance or unanticipated pump failures.
