The Orange County Sanitation District has an award winning source control program. The source control program has helped decrease the amount of toxic pollutants entering the sewer. Businesses that release wastewater into our sewers must meet strict regulations that keep toxic pollutants out of the sewer.

Our source control inspectors monitor the results of testing to see if there are any violations of the ordinances by businesses. The Orange County Sanitation District responds to all ordinance violations through warnings, fines and if necessary criminal charges.



 Industrial Wastewater Discharge Permit

The permit program limits the discharge of specific pollutants from industrial facilities by establishing numeric discharge standards, discharge requirements, self-monitoring requirements and report requirements. 

 Special Purpose Discharge Permit

A Special Purpose Discharge Permit is issued by Orange County Sanitation District for water and wastewater discharges to the sewerage system when no alternative discharge points exist other than the sewer system and/or alternate discharge methods pose an environmental impact or threat. 

Wastehauler Permit

OCSD operates a wastehauler station at Plant No. 1 for the disposal of septage, chemical toilet, and grease trap wastes only. Liquid waste pumpers must register with the Orange County Health Care Agency and obtain a Wastehauler Permit from OCSD.

 Fats, Oil, & Grease Wastewater Discharge Permit 

OCSD established a program to eliminate the discharge of FOG-containing wastewater from food service establishments (FSE) and commercial kitchens. Restaurants are now required to store fats, oils, and grease in containers that are picked up by permitted recycling and rendering facilities.

Discharge Authorization Request

In some instances, if wastewater meets the terms and conditions of OCSD’s Ordinances, including the applicable prohibitions and effluent limits, then it may be discharged to the sewer via a Discharge Authorization Request.
