body
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.
TIMING CONCERNS
Timely completion of the overhaul is necessary to minimize the period during which OC San does not have an available spare MSP for the Bitter Point Pump Station. Restoring the spare-pump capability will allow OC San to respond promptly to future maintenance needs or equipment failures while maintaining pumping capacity and operational redundancy.
Replacement MSPs have long procurement lead times, making it impractical to quickly replace the spare if it is unavailable.
RAMIFICATIONS OF NOT TAKING ACTION
Not proceeding with the repair would leave OC San without a serviceable spare MSP for the Bitter Point Pump Station. If an installed pump requires maintenance or experiences an unanticipated failure, the station could have reduced pumping capacity and operational redundancy for an extended period, increasing the risk of a wastewater backup, service disruption, or sewer spill.
PRIOR COMMITTEE/BOARD ACTIONS
August 2025 - Approved Flo-Services, Inc. as an Original Equipment Manufacturer (OEM) Sole Source provider for Hidrostal Pump Repairs and Services.
ADDITIONAL INFORMATION
Flo-Services, Inc. is Hidrostal’s sole authorized representative in OC San’s service area and is qualified to perform the required pump repairs. A 20% contingency is recommended to address additional repairs or replacement components that may be identified after the pump is disassembled and inspected.
