What size septic tank do I need for my house?

Tank size follows bedroom count, not square footage. A three bedroom home in Spartanburg typically calls for a 1,000 to 1,250 gallon tank, and a four bedroom home moves up to 1,500 gallons. We confirm the size against the county requirement before we order the tank.

What is a perc test and do I really need one?

A percolation test measures how fast water drains through your soil and helps confirm the seasonal water table. Spartanburg County requires it before permitting a new system, because the perc rate sets how large your drainfield has to be. We run the test and read the soil profile as part of the evaluation.

How long does a full septic installation take?

Once the permit is in hand, a straightforward conventional install is usually a two to three day job for the tank, distribution box, and drainfield, plus inspection and backfill. Mound and aerobic systems take longer. Wet weather and rocky ground can stretch the schedule, and we tell you up front.

Concrete, polyethylene, or fiberglass tank, which is best?

Concrete is the heavy, long lasting standard and the most common choice around Roebuck and Boiling Springs. Polyethylene and fiberglass weigh far less and resist rust and corrosion, which helps on tight access lots. We walk you through the trade offs for your site and budget.

How often should the tank be pumped after install?

The EPA guidance is roughly every three to five years, depending on tank size and how much water the household uses. Pumping on schedule protects the drainfield, which is the most expensive part to replace, so it is the cheapest insurance you can buy for a $5,000 field.

What permits and setbacks does a septic install need here?

Every new system runs through the Spartanburg County health department: a perc test, a permit, and a signed as-built record. Setbacks matter too. The tank sits at least 50 feet from a private well and the drainfield 100 feet back, with four feet of vertical separation to groundwater or bedrock.

Five Signs Your Septic Drainfield Is Starting to Fail

July 1, 2026

A drainfield rarely dies overnight. It sends warnings for months before it quits, and homeowners who catch those signs early often save the field instead of paying to rebuild it. After years of pulling failed systems across Spartanburg County, we see the same five tells over and over. Here is what to watch for.

Water Pooling Over the Field

The clearest sign is soggy ground or standing water above the drainfield, even when it has not rained. When the soil can no longer absorb effluent, it pushes to the surface. If a patch of yard near the field stays wet and spongy through a dry week in July, the field is struggling to disperse what the 1,000 gallon tank is sending it.

Slow Drains and Gurgling Fixtures

When toilets flush slowly and drains gurgle throughout the house, the whole system is backing up, not just one clogged pipe. A single slow sink is a plumbing issue. Every drain in the home slowing down at once points downstream to the tank or the field.

Bright Green Grass in One Strip

Grass that is noticeably greener and taller directly over the drainfield lines is not a good thing. It means partially treated effluent is surfacing and fertilizing the lawn. That untreated water is exactly what the soil is supposed to be filtering.

Sewage Odors Outdoors

A working system is sealed and vented, so you should not smell it. Persistent sewage odor around the tank or field means effluent is reaching the surface or the tank has lost its seal. That is often the point where a septic tank replacement becomes the smarter fix than another patch.

Backups Inside the House

The worst sign is wastewater backing up into tubs and floor drains. By then the field is usually saturated. If you are seeing this, stop running water and call before the problem spreads to the rest of the drainfield installation and forces a full rebuild.

What to Do Next

Catching two or three of these early often means the field can still be saved with pumping, a distribution box repair, or resting the system. Wait too long and the only fix is a new field, which runs several times the cost. The honest answer depends on your soil and how far the trouble has gone, which is why we start every call with an on-site look rather than a phone quote. You can reach us any time through our contact us page.

Theweeklytimes provides septic tank installation in Spartanburg, SC, and our crews handle the whole onsite wastewater system from the tank to the last drainfield trench. New septic system installation, septic tank replacement, drainfield and leach field construction, aerobic treatment unit setup, perc testing and site evaluation, and distribution box repair are all everyday work for us. We have set watertight 1,000 gallon concrete tanks in Converse Heights, replaced failed units along Reidville Road, and built pressure dosed fields out past the 29301 line on the west side of town.

A septic system spends its whole life buried, so most of what separates a system that runs thirty years from one that fails in five happens down in the ground where a homeowner never sees it. That is where real field experience earns its keep. Reading a soil profile, sizing a drainfield off the perc rate instead of a guess, setting the distribution box dead level so every lateral gets an even share of effluent: none of that shows up in a brochure, but it is the difference between a quiet system and a wet backyard off Country Club Road.

Every install in Spartanburg County runs through the health department, and we handle that paperwork the right way. That means a permit before we dig, a percolation test and site evaluation to confirm the soil and the seasonal water table, and the required setbacks (a septic tank at least 50 feet from any private well and the drainfield 100 feet back, with four feet of vertical separation to groundwater or bedrock). We build to the as-built the county signs off on, not to whatever is fastest, so your system passes inspection near Fernwood Drive the first time.

Because we work here, our estimates are plain and our number is in writing before a shovel moves. A straightforward tank swap runs one range, a full conventional system for a three or four bedroom home runs another, and a mound or aerobic build for tight or wet lots runs higher. We tell you which one your ground actually calls for after we walk it, whether the property sits in Hampton Heights or out toward Boiling Springs. No upsell, no surprise line items after the backfill.

The Septic Services Our Crews Perform

One experienced crew for the whole system, from the first perc hole to the final backfill.

New Septic System Installation

Full design and install of the tank, distribution box, and drainfield, sized off bedroom count so a typical three bedroom home gets a 1,000 to 1,250 gallon tank.

Septic Tank Replacement

We pull a cracked or failed tank and set a new watertight concrete, polyethylene, or fiberglass unit, most often a 1,000 to 1,500 gallon size matched to the household.

Drainfield and Leach Field Installation

Gravel trench or plastic chamber fields built to the perc rate so treated effluent disperses instead of surfacing or backing up into the house.

Aerobic Treatment Unit (ATU) Installation

Oxygen fed advanced units certified to NSF/ANSI Standard 40 for small lots and poor soils where a conventional gravity field will not pass.

Perc Test and Site Evaluation

Soil percolation testing and a profile evaluation that confirms drainage speed and the seasonal water table before the county will issue a permit.

Distribution Box and D-Box Repair

Reset or replace a settled or clogged distribution box so effluent splits evenly across the laterals instead of drowning one trench.
