BACKGROUND
The Orange County Sanitation District (OC San) Plant No. 2 PEPS conveys non-reclaimable primary-treated wastewater to the Activated Sludge (AS) process for secondary treatment prior to discharge through the ocean outfall. The PEPS Pump Station is comprised of four pumps that were originally installed over 40 years ago by Project P1-16 in 1981.

* Maintain a proactive asset management program
* Operate and maintain facilities to minimize impacts on surrounding communities,including odor, noise, and lighting
