Septic System

Once you have completed the OSSE you will continue to work with a licensed professional to apply for an On-Site Wastewater System. A Septic System Contractor must possess a State of California Contractor’s license (Type A, B, C-36 or C-42) to construct, enlarge, alter, repair improve or replace an individual system.

Please keep in mind that the licensed professional will work with you to install the system but they may have you fill out the applications. This can be done online through our Accela Citizen Access Portal
