DISCHARGE PERMITS

WORKING WITH US

If you have a non-domestic process flow, or any discharge in addition to bathrooms or sinks, contact the District’s Pretreatment Program Coordinator at (707) 429-8930 or sourcecontrol@fssd.com for information on permitting requirements.

The District’s Wastewater Discharge Ordinance sets requirements for discharges into the wastewater collection and treatment system. You may download a copy of the Wastewater Discharge Ordinance (724k PDF) here.
