More than 2.6 million Texas homes sit on a tank, and roughly 43,000 new systems get permitted every year. We build the websites, county pages, and review engines that put septic companies in front of that growth. Flat $1,500 a month, built from day one around how Texans actually search.
The Texas market
No state comes close. Texas has over 2.6 million on-site sewage facilities in service, roughly a quarter of the state's homes, and TCEQ's permitting data shows about 43,000 new systems authorized in 2025 alone. The reason is simple: Texas growth keeps landing past the end of the sewer line. Subdivisions in unincorporated Montgomery, Parker, Williamson, and Comal counties get built on septic because extending municipal sewer out there costs more than the lots. Every one of those rooftops is a future pumping, inspection, and repair customer, and the first company they meet is whoever ranks when the search happens.
Here is what should interest you more than the size: the gap between demand and online competition. Type a septic problem plus almost any Texas county seat into Google and you will find two or three thin, decade-old websites and a wall of Yelp and Angi listings trying to fill the vacuum. The directories rank because nobody local has built anything better. A septic company with a real page for each county it serves, current reviews, and a managed Google profile does not need to outspend anyone to take that ground. It just needs to be the first operator in its area to do the work properly.

Licensing & trust
Septic work in Texas runs through the Texas Commission on Environmental Quality, and your customers' county permitting offices know exactly what each license class means. A website that shows your TCEQ license class and number up front converts better with the three audiences that matter: homeowners comparing strangers, realtors on inspection deadlines, and county designated representatives who decide how smooth your permits go.
An Installer I license authorizes conventional tank-and-drainfield work: septic tanks, absorptive drainfields, leaching chambers, and similar standard systems. Aerobic units and other advanced systems are off the table until you hold Installer II.
The upgrade path requires holding Installer I for at least one year plus sworn statements verifying three installations, then the TCEQ exam. If your crew has it, your website should say so, because it is the difference between quoting every system type and turning work away.
Maintenance providers must hold an Installer II license plus a Class C or higher wastewater operator license, or have three years as a registered maintenance technician behind them, and the techs running your routes must be registered with TCEQ. Aerobic contracts are the best recurring revenue in Texas septic, and the license is the gate.
TCEQ occupational licenses run three years with continuing education to renew. Your license number belongs in your website footer and on every service page, where inspectors, lenders, and county agents actually look for it.

Where the work is
Clay soils, a high water table, and hurricane-season flooding make drainfield failure a way of life in the counties ringing Houston. Montgomery, Liberty, and Waller counties keep adding septic subdivisions, and emergency searches spike after every major rain event. Repair-focused pages earn their keep here.
The fastest-growing septic belt in the state runs through Parker, Kaufman, Ellis, and Johnson counties, where DFW sprawl outruns the sewer lines. Expansive North Texas clay swells and shifts with the drought-and-downpour cycle, cracking tanks and heaving lines, which keeps repair demand steady between installs.
Rocky Hill Country ground and Edwards Aquifer recharge rules push a large share of installs to aerobic systems, which means maintenance contracts, which means recurring revenue. Comal and Kendall counties are among the fastest growing in America, and every new home on those limestone lots needs a licensed installer.
Williamson, Hays, and Bastrop counties absorb Austin's overflow, and a meaningful share of it lands on septic. The customer here researches everything online first, reads every review, and books the company that answered their cost question before anyone else did. Content wins this market.
From Tyler to Lufkin, sandy soils and rural acreage make conventional systems the norm and keep install prices competitive. Competition online is thinnest here: county-level searches routinely return directories instead of actual companies, which is exactly the vacuum a real website fills.
Seasonality
Spring storm season is the emergency season. May and June downpours saturate drainfields that limped through the year, and backed-up showers follow within days. The companies that own the emergency and repair searches before the first big front rolls through collect a disproportionate share of the year's least price-sensitive work. Summer brings the real estate wave: Texas closings cluster from April through August, and every rural transaction drags a septic inspection deadline behind it, with realtors choosing whoever answers fast and looks credible.
The bake matters as much as the soak. A long Texas drought shrinks clay soils away from tanks and lines, then the first hard rain shifts everything, and the phone rings with mystery wet spots and sewage smells. Winter is the slow stretch, and it is exactly when the next spring's rankings get decided, because Google moves on a delay of months. The Texas septic company that builds its pages and review base from November to February is the one positioned at the top when the storms come back. Start ahead of the season, not inside it.
