BACKGROUND
The Effluent Pump Station Annex (EPSA) generators provide emergency back-up power for the EPSA pumps and the Ocean Outfall Booster Station (OOBS) pumps. The headworks generators are used to generate back-up power for the main sewage pumps, the washer compactors, the odor control system and ancillary equipment.
RELEVANT STANDARDS
* Protect OC San assets
* 24/7/365 treatment plant reliability
* Maintain a proactive asset management program
PROBLEM
During routine preventative maintenance, Orange County Sanitation District (OC San) discovered coolant leaking from Headworks Generator No. 1 and EPSA Generator No. 3. Further inspection determined that both radiators were leaking coolant. Although multiple repairs were made, the leaks persisted.
PROPOSED SOLUTION
Approve a General Services Contract to replace both radiators for Headworks Standby Generator No. 1 and EPSA Standby Generator No. 3 with in-kind equipment to restore the full operational capacity and reliability of the standby generation systems.
TIMING CONCERNS
Due to the long lead times for replacement parts and the critical nature of these generators, it is essential to begin this work as soon as possible to maintain operational readiness.
