OC San is the regional sewer provider for an almost 500 square-mile area of central and northwest Orange County; however, we do not operate the local sewer and therefore, do not issue local sanitation clearances.
If you live in the unincorporated areas within OC San's service area, our Sanitation District Clearance Map has got you covered. This handy tool will help you find the right provider to get the necessary sanitation clearances.
Residents within city limits should contact their city’s Public Works or Utilities Department for information about local sewer service providers.
Use our map to search by your address or current location and discover which local sanitation district is responsible for your area, along with their contact information. If you need further assistance, please send an email to permitcounter@ocsan.gov.
