The City of Porterville Wastewater Facility is designed to treat 8 million gallons of domestic wastewater per day. Wastewater is "used" water that goes down the drain when you flush the toilet, take a shower, wash your clothes or dishes.
Wastewater is treated and purified through mechanical and biological processes and eventually makes its way to supply farming operations 4.5 miles outside of town.

For more information, kindly schedule a tour of the facility or download our WWTF Booklet via the links below.
