The Orange County Sanitation District (OCSD) is a public agency in the state of California that provides wastewater collection, treatment, and disposal services for approximately 2.6 million people in central and northwest Orange County.
OCSD has two operating facilities that treat wastewater from residential, commercial and industrial sources.
The trunklines connect into a common discharge channel located at the Headworks D facility.
The washer compactors help remove organics, which are odor causing and take up space in hauling bins.
Grit material consisting of inorganics, like eggshells, corn, and sand and dirt, is removed from wastewater to prevent damage to pumps and disruption of other processes like sludge digestion by consuming unnecessary space.
Bleach (NaOCL) may also be added into A, B, and/or C splitter boxes to work to assist in sludge settling.
