Septic systems are used for underground wastewater on-site wastewater disposal for structures that do not have access to public sewer. They treat wastewater from plumbing produced by bathrooms, kitchen drains and laundry.
Please refer to the following information to find out what is needed to install a new septic system and what to do if you already have one.

Before applying for a new septic system, it is necessary to have a valid soils testing (On Site Soils Evaluation - OSSE) done. Please refer to the below tabs for more information on how to apply.
An OSSE includes soil tests that determine the effectiveness of soil to filter sewage through leach lines, as well as observations of required setbacks, constraints and possibilities for an individual, “on-site” septic system. The report produced by the consultant of the particular site tested on a parcel is reviewed and evaluated by an Environmental Health Specialist who generates a findings report.
An OSSE must be conducted by a Nevada County approved Soil Testing Consultant. Reports are valid if completed after 1998, with a possibility of extending back to 1991 pending Consultant re-certification. (link from zander for validity of reports)
It is recommended to have the consultant apply for the OSSE permit, as well as schedule insections to conduct the OSSE. This can be done by calling the number below under OSSE Scheduling. Once the permit is issued and you have completed your final inspection, you can proceed to apply for a Septic Permit Application.
HOW TO APPLY FOR AN OSSE
- Hire a Nevada County Approved Soils Testing Consultant
- Apply Online (Note: You will need your Consultants contact information to apply online)
- Consultant schedules an OSSE (see below)
- Consultant and Nevada County Specialist meet on site for soils testing
- Consultant submits Soils Evaluation Report to Nevada County
- Nevada County Specialist generates Findings Report to approve what type of septic system to install
- You may then proceed to apply for a Septic Permit (see above tab)
Scheduling an OSSE
Updated: February 14, 2018
We are now scheduling OSSE's for the week of February 26th - March 2nd
Please Note: The County will try to accommodate requested dates but cannot guarantee availability.
To schedule an OSSE, please call (530)265-1599.
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

If you have an existing septic system that is failing or needs to be repaired, please contact a Licensed Professional for a site visit. The Licensed Professional will determine the issue and will be able to advise you on the next step of the submittal process for septic repairs or new replacements.
The best way to locate your septic system is with a Septic As-Built. An As-Built shows the exact location of your septic system after installation. If you do not have this, please fill out a Public Records Request to gain access to files we have on your parcel.
Once you have your As-Built, you can use a simple method of probing the soil with a metal rod or you can hire a professional to find and trace the system's lines. We do our best to retain records of every property in Nevada County, however occasionally we do not have all records on file. If you cannot acquire an As-Built for your parcel, a professional can trace the lines for you
Depending on the the size of your system and how many bedrooms it is approved for, you may have to either modify your current system so it can accommodate another bedroom or convert an existing bedroom so it is not longer one. Some systems are approved for more than the current number of bedrooms. In this case, you would not have to modify your septic system. Please refer to your approved septic permit for your property to find out how many bedrooms it is approved for.
If you are adding a second unit, it is required to have it's own septic tank if it is not attached directly to the original building. The additional septic tank can be tied into the existing leach field if the total number of bedrooms does not exceed the number of bedrooms that the system was designed for. If the number of bedrooms if greater than the bedroom capacity for the existing system, you will need to apply for an OSSE and a Septic Modification Permit to expand the system. As before, please contact a licensed professional to determine what is right for you.
If you have any questions on additions, please don't hesitate to contact us.
The Nevada County Land Use Ordinance requires Pressure Dose and Treatment Systems to be monitored annually by a certified Septic Service Provider. Prior to finalizing of these systems, the parcel owner is required to record a Right of Entry (Maintenance and Monitoring) Agreement and apply for a Certificate of Operation (Annual Permit) for either Pressure Dose or Treatment System. Forms and fees can be found below.
