BACKGROUND
The Main Sewage Pumps (MSPs) at Orange County Sanitation District’s (OC San) Plant No. 1 are critical to wastewater treatment operations. These pumps convey incoming wastewater from the collection system through the headworks to downstream treatment processes. Reliable operation of the MSPs is essential to maintain wastewater conveyance capacity, accommodating variations in incoming flows, and providing sufficient pumping capacity during peak flow conditions.
Project No. P1-105, Headworks Rehabilitation at Plant No. 1, is currently underway and plans to install five new MSPs during the next dry weather season. The project includes spare parts for the new pumps but does not provide a complete, ready-to-install spare pump assembly. Due to the pumps' critical function, specialized design, and importance to plant operations, maintaining a complete spare MSP is essential to minimizing extended equipment outages and preserving wastewater conveyance capacity.
RELEVANT STANDARDS
24/7/365 treatment plant reliability
Protect OC San Assets
Protect public safety
Maintain a proactive asset management program
