Well and Septic Installation for New Construction in SC

If you just bought land in South Carolina with no water and no sewer hookup, you need a well and septic installation before you can build anything on it. Austin Drilling handles both jobs in-house, using the same crew and the same point of contact from the first site visit to the final county inspection. That matters because a well and a septic system have to be placed a specific distance apart and permitted through your county before either one goes in the ground, so coordinating them as one project instead of two separate contractors saves you weeks and a lot of back-and-forth.

Why do new properties in South Carolina need both a well and a septic system?

Most rural and semi-rural land in the Midlands and Upstate sits outside city water and sewer lines, so a private well and an on-site septic system are the only way to get running water and handle wastewater. We hear this constantly from people who just closed on a piece of land: an old farm field they want to build on, a half-acre lot they bought to downsize onto, a rural property they are turning into an off-grid tiny home site. None of those properties have a hookup waiting for them. The well supplies the house, the septic system handles everything that goes down the drain, and South Carolina's Department of Environmental Services requires both to be permitted and inspected before you get a certificate of occupancy.

This is different from repairing an existing well or septic system on a property that already has one. If your water just stopped or your septic is backing up, those are service calls, not new installations, and we treat them differently. New construction starts from bare ground, which means the well site and the septic drain field both have to be chosen with the other one in mind from day one.

Can one company handle both the well and the septic installation?

Yes, and that is worth confirming before you hire anyone, because plenty of companies only do one or the other. Austin Drilling is dual-licensed for well drilling and septic work, so our own crews handle the drilling, the pump installation, the septic tank and drain field, and the county coordination for both permits, without handing your project off to a second contractor halfway through. You get one point of contact from your first call through the final walkthrough, instead of chasing down a well driller and a septic installer separately and hoping their schedules and their placement decisions actually line up.

That coordination is the part that trips people up when they hire two different companies. A well has to sit far enough from the septic tank and drain field to keep wastewater from ever reaching your drinking water, and the exact distance depends on your county's health regulations and your soil. When one crew plans both, that separation gets built into the site plan from the start. When two separate companies each show up with their own equipment and their own opinion about where things should go, you are the one stuck refereeing it.

What order do the well and septic go in on a new property?

The septic side typically starts with a percolation test, which tells the county how well your soil drains and determines what kind of septic system your lot can support. That test and the resulting design have to be approved before the drain field location is locked in, and the well site gets picked with that drain field in mind so the required separation distance is met on the first try instead of after a rejected permit. Once both plans are approved, drilling and septic installation can often move in parallel rather than one waiting on the other, which is one of the real time advantages of using a single crew for both.

Permitting is the part that takes the longest, not the physical work. The septic design, county approval and inspection scheduling can take a few weeks depending on your county's current workload, and the well permit runs through SCDES. Once permits clear, Austin Drilling typically completes septic installation in one to three days and well drilling in one to three days as well, though both depend on your site's soil, depth and access. Building the permitting timeline into your construction schedule early is the single biggest thing you can do to avoid delays on move-in day.

What goes into the price of a well and septic installation?

Rather than quote a number that won't match your property, it helps to know what actually drives the price up or down. Your soil's perc rate is the biggest factor on the septic side, since poor-draining soil sometimes needs a larger or more advanced system than a straightforward conventional one. On the well side, depth is the biggest factor, and South Carolina's geology varies enough between the Upstate and the Lowcountry that two properties a few miles apart can need very different depths. Site access matters too, since a wooded lot with no existing driveway takes more time and equipment to reach than a cleared building site.

Because every property is different, the only accurate way to price a combined installation is a real site visit, not a phone estimate. Austin Drilling offers financing for well, pump and septic projects, so if you are already juggling the cost of building on raw land, ask about payment options when you request your quote rather than assuming it is out of reach.

What if I'm building off the grid or on raw land with no water or sewer at all?

This is the situation we hear about most often from people buying land in South Carolina, and it covers a handful of specific scenarios:

• A recently purchased lot or old farm field with no existing utilities at all.
• A downsizing move onto a smaller property that was never built on before.
• An off-grid or tiny home build that intentionally skips city hookups.
• A property connected to city water but not sewer, where you still need a septic system even though the well side is already handled.

Every one of those starts the same way: a site visit to walk the property, check access, and get a feel for the soil before anything gets permitted. If you already have a survey or a perc test from a previous owner, bring it, since it can save a step. If you don't, that is normal for raw land, and it is one of the first things we sort out.

Frequently asked questions

Do I need a permit for both the well and the septic system?

Yes, the well goes through SCDES, and the septic system goes through your county's environmental health office with an approved design and a perc test. Austin Drilling coordinates both as part of a well and septic installation, so you aren't filing two sets of paperwork with two different companies.

Can the well and septic system be installed at the same time?

Yes, once both are permitted, drilling and septic work can often happen close together rather than one waiting on the other, since the same crew is coordinating both. The permitting stage is almost always the longer part of the timeline, not the physical installation.

What if my land has never had a perc test?

That is common on raw land. A perc test is one of the first steps for any new septic system and gets scheduled as part of your site visit, well before installation begins.

Is a well and septic installation different from repairing an existing system?

Yes, repairs and replacements on a property that already has a well or septic system are service calls we handle separately, while a well and septic installation is for a property that has neither yet, most often new construction or a recent land purchase.

Do you install septic systems on properties that already have city water?

Yes, some properties have access to city water but no public sewer line nearby, which still requires a private septic system even though the well side isn't needed.
