Introduction

If you're installing a new septic system or making a major repair in Spartanburg County, you'll need a permit before any work starts. The process runs through the state, not the county, and it includes a soil evaluation that determines what kind of system your property can actually support. Here's how it works, in plain English, so you know what to expect before you start.

Do You Need a Septic Permit?

You need a permit for new installations and major repairs. You generally don't need one for routine maintenance like pumping. Here's the rough line:

You need a permit for – installing a new septic system, replacing a failed system, repairing or replacing a drain field, or any major modification to the system.

You usually don't need one for – routine pumping, minor repairs that don't touch the tank structure or drain field, or simple maintenance.

If you're not sure which category your project falls into, it's worth asking before you dig, because doing permitted work without a permit can mean fines and having to redo it.

Who Issues the Permit (It's the State, Not the County)

In South Carolina, septic permits are handled by the South Carolina Department of Environmental Services (SCDES), through its Upstate Regional Office, which covers Spartanburg County. The rules come from state Regulation 61-56, which governs onsite wastewater systems. So even though it's your local property, the permitting authority is the state environmental agency, not Spartanburg County's building department.

The Soil Evaluation

This is the step people don't expect, and it's the most important one. Before SCDES issues a permit, your property needs a soil evaluation (also called a site evaluation). An evaluator examines the soil to determine how well it drains and what kind of system the site can support. This can be done by certified SCDES staff or, under the state's rules, by a licensed Professional Soil Classifier.

This matters a lot in Spartanburg County specifically. The Upstate sits on heavy Piedmont clay — the Cecil, Pacolet, and Madison soil series over granite and gneiss bedrock — and clay drains slowly. A site with poor-draining soil may require a larger drain field or an alternative system design rather than a conventional one. The soil evaluation is what determines that, so it shapes both what you can build and what it'll cost.

The Fee and the Timeline

The SCDES site evaluation fee is $150, paid when you submit your application. That's the state fee specifically — your total project cost is higher once you add the system design, the installation itself, and any work a Professional Soil Classifier or engineer does if your lot needs an alternative system. A new septic permit, once issued, is valid for 5 years.

Timeline varies with the season and the office's workload, but expect the permitting process — application, soil evaluation, and approval — to take a few weeks, not a few days. Wet weather can delay site visits, since soils are evaluated dry. Build that into your plans, especially if you're on a construction timeline for a new home.

How Applications Are Submitted

SCDES handles septic applications through its online ePermitting Portal, using the Onsite Wastewater System Application (form D-1740). Part of the process involves posting site location cards on the property and clearing the area around the proposed septic location so the evaluator can assess the soil. A legal description of the property (plat, deed, or survey) is submitted with the application.

The Basic Steps

• Apply to SCDES through the ePermitting Portal (form D-1740) and pay the $150 site evaluation fee

• Soil evaluation is performed to determine what the site can support

• System design is created and sized based on the soil and your household

• Permit is issued once the design is approved (valid for 5 years)

• Installation is done by a licensed installer to the approved design

• Final inspection signs off that the system was installed to code

When to Bring in a Professional

You can navigate the permitting yourself, but most homeowners have their septic installer handle it, because the installer deals with SCDES, soil evaluations, and R.61-56 designs regularly and knows what the Upstate office expects. A licensed installer is required for the construction itself. A good local installer will manage the whole process — application, soil eval, design, and final inspection — so you're not learning the state's system from scratch on your own project.
