body
BACKGROUND
Orange County Sanitation District’s (OC San) Plant No. 2 Headworks facility has seven Main Sewage Pumps (MSP) that transfer wastewater from the Bar Screen facility to the discharge channel and grit basin. MSPs #1 through #3 are dedicated to non-reclaimable flows and MSPs #4 through #7 are dedicated to reclaimable flows when operating in separated mode. Plant No. 2 MSPs allow for the treatment of all the wastewater flows that are routed to the plant.
RELEVANT STANDARDS
• 24/7/365 treatment plant reliability
• Maintain a proactive asset management program
• Meet volume and water quality needs for the GWRS
PROBLEM
MSP #7 was offline for approximately one year to complete Variable Frequency Drive (VFD) repairs. When the pump was brought back online, it was found to require additional mechanical repairs. A detailed inspection performed by Bender CCP, Inc., at its facility confirmed the need for multiple repairs and component replacements to restore the pump to reliable service.
PROPOSED SOLUTION
Approve a Sole Source Purchase Order to Bender CCP, Inc. for the inspection, repair, replacement, and re-assembly of parts for Main Sewage Pump #7 at Plant No. 2.
TIMING CONCERNS
Given the long lead times of some parts and criticality of these pumps, it is essential to commence this work as soon as possible to ensure operational readiness.
RAMIFICATIONS OF NOT TAKING ACTION
The Influent Pump Station at Plant No. 2 now has reduced redundancy due to the separation of reclaimable and non-reclaimable flows that pass through this process station. Insufficient pumping capacity would lead to operating in combined mode, affecting OC San's commitment to supply required flows to the Ground Water Replenishment System.
