Application Fee: $150
- Step 1: Read and fully complete the Onsite Wastewater System Application and submit it to your local Environmental Affairs Office. You will also need to submit a copy of the property’s plat or deed. If you do not have a copy of the plat or deed, click here for more information on how to obtain a copy. Once your application has been received, office personnel will contact you to confirm receipt of your application and to discuss electronic payment options. We do not accept cash payments. For a reference guide on how to complete the application, please refer to this example, Onsite Wastewater System Application.
- Step 2: Your application will be reviewed to be sure that all necessary paperwork is included. If everything is in order, your application fee will be accepted.
- Step 3: If a site visit is required, the inspector will evaluate the site’s suitability for a septic system. If the inspector approves your site for a traditional septic system, they will issue you a Permit to Construct. If the inspector does not approve the permit, they will discuss possible alternatives with you. Test pits may be requested by the Department in cases where the evaluator encounters an obstruction during initial site evaluation or when an area is known to require test pits due to soil characteristics. Soil conditions requiring test pits are most commonly found in the midlands and upstate regions of the state. Note: Test pits may not be an option in coastal and sandy areas of the state. Speak with your local office staff for more specific guidance for your area.
- Step 4: Once you have been issued a Permit to Construct, you may contact a licensed onsite wastewater system installer to install your septic system.
- Step 5: Before completing the installation of the septic system, the installer must contact DHEC to schedule a time for the inspection of the septic system before it is covered. If a DHEC inspector does not arrive within 30 minutes of the scheduled time, a licensed installer has the option to proceed with a self-inspection of the installation. Documentation must be provided by the installer to the Department on the DHEC approved form D-3978, Contractor Approval to Operate.
Permit Expiration and Modifications: Permits to Construct are good for five years. To renew your permit after five years or to make changes to it once approved, you will need to complete a new application and pay the fee again.
The fee and permit are authorized by these regulations:
Because incorrectly installed septic systems can harm water quality and make people sick, South Carolina law requires site approvals and permits for all septic systems.
If you are planning to build a home or place a manufactured home on property not served by a public or community sewer system, you must first obtain DHEC's approval and a permit to install a septic system. Without this permit, your county will not be able to issue you a building permit.
Please be aware of how the weather affects our schedules. If the soil is too wet, we may not be able to do a proper evaluation. Soil evaluations may have to be delayed until the soil has had time to dry out which adds to the time it takes to issue your permit. This is similar to farmers having to delay planting or harvesting their crops. If there has been too much rain, they can't get into the field with their equipment to conduct their work.
To file a septic system application, download and complete an onsite wastewater application and submit it to your local Environmental Affairs Office.

If you have any questions, please call your local Environmental Affairs Office for assistance.
If you install, clean, or repair septic systems or if you haul and dispose of sewage from septic systems and portable toilets, you must be licensed by DHEC and renew your license each year.
Download and complete the application form for a License to Construct or Clean Onsite Wastewater Systems and Self-Contained Toilets. If you are applying for a septic system installer license, contact your local DHEC Environmental Affairs office to make arrangements for testing.
The licensure and annual renewal fees for onsite wastewater system installers and pumpers/haulers are listed below:
- License to construct - $100
- License to clean - $100
- License to construct and clean - $150
- Master Contractor license - $200
You must pay these fees each year in order to renew your license. If we don’t receive your payment by the due date, a late fee will be charged.
Your license to work on septic systems or haul sewage will expire if you fail to pay your renewal fees and late fees within 90 days of the renewal due date.
Installer and Master Contractor Exams
The first time you apply for a license to construct work with septic systems and/or sewage disposal or a Master Contractor license, you must pass an exam that tests your understanding of Regulation 61-56. To pass, you must score 80% or better. If you do not pass this test, you can retake it in 30 days. If you fail to pass a second time, you can wait 60 days and retake the exam a third time. Once you are granted a license, you will not have to retake the test as long as you pay the annual license renewal fees and submit all necessary documentation. If you allow your license to expire, you will have to repeat the new license process from the beginning.
Other License Requirements
