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 the gravity flow system cannot be used to transport wastewater to the treatment plants. The pumps in these stations require routine removal and restoration activities to maintain design capacity output due to normal wear and tear. These pump stations are critical to the collection system operation and may result in a backup or sewer spill in the event of losing pumping capacity.

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

The main lift pumps at College and Westside Pump Stations require removal for overhauls. However, without spare replacements on hand, this process leads to a temporary loss of pumping capacity. Additionally, the extended lead times in modern supply chains for required overhaul services reduce system redundancy, increasing the risk of service disruptions.

PROPOSED SOLUTION

Approve the purchase of spare rotating pump assemblies from Flo-Systems, Inc. for the Westside and College pump stations to maintain asset availability and minimize operational downtime.
