EBMUD Water Treatment Plant

The EBMUD water treatment plant processes the wastewater of the entire East Bay Area.

According to an EBMUD employee, every day 9 trucks transport human manure from this facility to the Central Valley Compost Facility, which is also referenced on the EBMUD website.



The Synagro Central Valley Compost Facility processes municipal sewage (AKA biowaste solids, human feces) and greenwaste into compost, concentrates, and fertilizers to sell to nearby farms. According to their website, they process 99,999 tons* of material annually.
