The classic signs of a full septic tank are slow drains, gurgling pipes, sewage odor near the tank, wet ground over the drain field, and a backup at the lowest fixture. None of them proves it. A pumper settles the question by measuring two layers inside the tank, not by looking at the water level. […]
Texas requires one chemistry and one chemistry only in an aerobic septic chlorinator: calcium hypochlorite tablets labeled for wastewater disinfection, under 30 TAC §285.33(d)(2)(D). Swimming pool tablets are a different compound, trichloroisocyanuric acid, and dropping them into a feed tube that has held calcium hypochlorite can start a fire or an explosion. The federal chemical […]
If you own an aerobic septic system in Texas, state law requires you to maintain it. For most owners, that means a paid contract with a TCEQ-licensed maintenance provider, with system checks reported to your county at least every 4 months. Published pricing spans $200 to $600 per year across Dillon Septic’s own 2026 pages. […]
Norweco Blue Crystal is the strongest pick on the evidence: 73% calcium hypochlorite, EPA Reg. No. 63243-4, formulated for the flow of a house rather than a plant. Texas law does not care which brand is on the pail, only what is in it: 30 TAC § 285.33(d)(2)(D) requires calcium hypochlorite labeled for wastewater, which […]
The best septic tank alarm in Texas is one that satisfies 30 TAC §285.34(b)(1): audible and visible, on a power circuit separate from the pump, with UL-listed components. The SJE-Rhombus Tank Alert XT is the overall pick, carrying both UL and CSA listings, rated for indoor or outdoor mounting, and specified by its manufacturer for […]
The Tuf-Tite EF-4 is the best septic tank effluent filter for most Texas homes: it is certified to ANSI/NSF Standard 46, which is the one certification Texas rules actually name, it is rated for 800 gallons per day with 86 feet of 1/16-inch filtration, and it costs about $36 to $46 at Home Depot and […]
Scott 1000 is the best toilet paper for septic systems: 1-ply, unscented, rated 100% septic-safe, with a claimed 10x faster dissolve rate than the leading soft-and-strong mega roll. It costs 9.1¢ per 100 sheets at Walmart (July 2026), a fifth the cost of Quilted Northern Ultra Plush. Household refuses single-ply? Cottonelle Ultra Clean and Angel […]
Drain field size is design flow divided by the soil’s loading rate, and both numbers come from your state’s rule, not a national chart. A three-bedroom house in sandy loam needs 1,200 square feet of absorptive area in Texas (240 feet of three-foot trench), 450 to 600 square feet of trench bottom in North Carolina, […]
Stop using water inside the house the moment you see a flooded drain field: soggy ground, standing water, or backup at your lowest drains. Don’t call for a pump-out. Pumping a tank while the soil is saturated can make it float, snapping the pipes connecting it to your house. Wait for the ground to firm […]
A 1,000-gallon septic tank serving four people needs pumping about every 2.6 years, and the same tank serving two people can go 5.9 years, according to the pumping table published by the Texas Commission on Environmental Quality (TCEQ). The three-to-five-year rule of thumb from TCEQ and EPA is an average. The table answers how often […]
Choose a septic company by checking three things you can verify and asking nine you cannot: the installer’s license class in the state’s public record, the pumper’s transporter registration, and the paperwork the rules already require them to hand you (a license number on the bid, a trip ticket at the truck, a construction account […]
Cleaning your own effluent filter is legal in Texas without a permit, a license, or a phone call to the county. Texas rule 30 TAC §285.2(35) defines maintenance to include “cleaning” and the “replacement of pumps, filters, aerator lines, valves, or electrical components,” and it says plainly that maintenance “does not include alterations.” That single […]
Start with your property records, not a shovel: your permit file, a home inspection report, or the as-built drawing on file with the local health department will usually show your tank’s exact location. It can turn a weekend of digging into a five-minute records request. If no drawing exists or it doesn’t match what you […]
Texas has not sized a septic system on a percolation test since February 1997. A Texas permit requires a site evaluation under 30 TAC §285.30, done by a TCEQ-licensed site evaluator or professional engineer, who digs two borings or backhoe pits, classifies the soil by texture, and looks for rock, clay, and groundwater within two […]
Septic service in rural Texas costs what it costs in town plus whatever it takes to get a truck to a gate, and that second number is the one nobody prints. Texas pumpers that publish a trip or service-call fee at all list $35 to $99; most publish a service radius instead and quote distance […]
There is no national septic tank size chart. The same three-bedroom house is required to have a 900-gallon tank in Pennsylvania, 1,000 gallons in Texas and Washington, and 1,500 gallons in Ohio. Every figure in the chart below is a legal minimum from a named state rule, read from the rule itself, not an average […]
Ordinary cleaners used as directed do not sterilize a septic tank. The only published dose-response work found it took about 1.85 gallons of bleach to kill the bacteria in a 1,000-gallon tank, with recovery in roughly 30 hours. The real risks are small doses that work, products that never break down, and water volume. Five […]
Standing water over the trenches, sewage odor outdoors, and drains that slow across the whole house are the signs of a failing drain field. The one that distinguishes it from everything else is timing: a failed field does not improve when the tank is emptied, and the symptoms come back within days. Most homeowners who […]
As of August 16, 2026, the septic-rule rewrite at the Texas Commission on Environmental Quality (TCEQ) has not been proposed, adopted, or made effective. The project is real and active, but still at the pre-proposal stage: no draft text, no Texas Register publication, no comment period, no commissioner vote. The last change to Texas septic […]
Texas law exempts one single-family home on a tract of 10 acres or more from septic permitting, but only if every part of the system sits at least 100 feet from the property line, all effluent stays on the property, and that home is the only dwelling on the tract. The exemption skips the permit, […]
Texas has no single septic permitting office. Authority is delegated county by county to 444 local “authorized agents” (counties, cities, river authorities, and health districts), and in 49 counties there is no local agent at all, so permitting runs through a TCEQ regional office instead. Filing with the wrong desk is the most common and […]
A standard residential septic permit costs $250 in Kerr County and $712 in Travis County, and every figure in the table below was read on the issuing county’s own fee document on September 3, 2026. Texas septic permit cost varies by county because there is no statewide fee: each county sets its own, revises it […]
Texas septic rules live in one place: Title 30, Chapter 285 of the Texas Administrative Code, enforced by TCEQ or by the county that TCEQ has delegated to. The rule is short on ceremony and specific on substance. You need a permit to build, alter, repair, extend, or operate a system unless you fit a […]
Texas sets one statewide table of minimum separation distances for septic systems: 30 TAC §285.91(10), Table X. A septic tank must sit at least 5 feet from a property line or building and 50 feet from a private well; a standard drain field (soil absorption system) needs 5 feet from the property line, 100 feet […]
Texas counties authorized 431,535 new septic systems between 2015 and 2024. Permits climbed every year through 2022, peaked at 54,593, then fell 21% in two years to 43,215 in 2024. Underneath that curve sits a technology shift most Texans never notice, and a geography so consistent you can predict a household’s septic system from its […]
Anyone drilling a water well for hire in Texas needs a license from the Texas Department of Licensing and Regulation, must set the well at least 100 feet from a septic drain field and 50 feet from a septic tank, and must send the owner a State of Texas Well Report within 60 days. Pumping […]
The standard list of septic system types has a structural problem, and the EPA’s own version of it shows the problem clearly. That list gives “aerobic treatment unit” and “mound system” their own headings, side by side, as though they were alternatives to each other. They are not. One is a decision about how the […]
Go to TCEQ’s free public license search at www2.tceq.texas.gov/lic_dpa, search the installer’s name or license number, and check two things: the license type says Installer I or Installer II (or Maintenance Provider, for aerobic system service), and the status reads CURRENT with an expiration date that hasn’t passed. The search is free, takes about a […]
A drain field is the part of a septic system where the soil does the treating. The tank only settles and separates. Everything that makes the wastewater safe to return to groundwater happens in a few feet of dirt underneath a set of buried trenches. The EPA describes it in one sentence: “The drainfield is […]
