Septic System Questions, Answered for West Texas

A septic system treats household wastewater on-site instead of sending it to a municipal treatment plant. Wastewater flows into an underground tank where solids settle and bacteria break them down, and the treated liquid then disperses into the ground through a drain field.

If you’re inside incorporated Odessa or Midland, you’re likely on municipal sewer, though there are exceptions. Most homes in unincorporated communities like West Odessa, Gardendale, Penwell, Notrees, and Goldsmith run on private septic systems, since municipal lines were never extended out that far.

The tank is where solids settle and partially decompose. The drain field is the separate area, usually a network of buried perforated pipe, where the treated liquid effluent actually gets absorbed into the soil. A problem with one doesn’t necessarily mean a problem with the other.

A well-maintained conventional system can run 25 to 30 years or more. Systems in this region that fight caliche-heavy soil or that get neglected on pumping tend to fall short of that. Regular pumping and not overloading the drain field are the two biggest factors within your control.

It’s the box that splits effluent evenly between the different lines of a drain field after it leaves the tank. A clogged or uneven distribution box can look exactly like a failing drain field from the surface — see the Drain Fields section below for how we tell the two apart.

Most commonly during a real estate transaction, but a routine inspection every couple of years is also a reasonable way to catch a small issue before it becomes an expensive one, especially on a system you inherited from a previous owner with no maintenance records.

Tank condition, sludge and scum layer depth, baffle and lid condition, the distribution box, and whether the drain field is absorbing effluent properly. Everything gets documented in a written report.

Usually within 2 to 3 business days of the appointment, faster if the transaction has a tight deadline and you flag that when you submit the request.

Not necessarily. Plenty of findings are minor and get resolved with a repair credit or a quick fix before closing. It’s the undocumented, unknown issues that tend to actually stall a transaction — a clear report, even one with findings, is usually a good thing for everyone involved.

It depends on the loan type and lender, but it’s common enough on rural and unincorporated properties around Odessa and Midland that we’d recommend budgeting for one regardless of whether it’s strictly required.

Wipes of any kind, even ones labeled flushable, grease, coffee grounds, cat litter, feminine hygiene products, and large amounts of chemical drain cleaner. Wipes in particular don’t break down and are one of the most common causes of a blocked line we run into.

A healthy tank already has the bacteria it needs from normal household waste. Most additives on the market aren’t necessary, and some can actually disrupt the natural bacterial balance rather than help it.

It adds more solid material to the tank, which speeds up how fast solids accumulate and typically shortens the interval between pump-outs. If you use a disposal regularly, it’s worth mentioning when we’re setting your pumping schedule.

Grass is fine and even helps with evaporation. Trees and shrubs with aggressive root systems are a problem — roots seeking moisture will grow toward and eventually into drain lines, which is a common cause of field damage we see on older properties.

With well under 15 inches of rainfall a year here, drain fields rarely deal with the saturation problems common in wetter climates. The tradeoff is that the caliche soil itself is slower to accept effluent to begin with, so a properly sized system matters more than usual.

Most commercial kitchens need service every 1 to 3 months, though high-volume operations — including many of the man-camp and oilfield-crew kitchens in this area — often need monthly service to stay compliant.

Fats, oils, and grease build up and eventually pass through into the drain line or septic system, where they can cause blockages and, for systems tied into municipal lines, code violations.

Any establishment producing significant FOG (fats, oils, grease) waste — most commercial kitchens — is generally required to have one under local plumbing code. Requirements vary by jurisdiction, so we’d recommend confirming with your local building authority.

FOG stands for fats, oils, and grease — the byproducts of cooking that solidify as they cool. A grease trap catches this material before it enters the plumbing system, where it would otherwise harden and block lines.

Yes. Given how much of the local economy runs on oil and gas, grease trap service for temporary housing kitchens and crew dining facilities is a regular part of our commercial work.
