Service · Septic Tank Sales

The right tank, properly sized and correctly set.

Concrete, fiberglass, or polyethylene, the tank type and size that belong on your property depend on your soil, your lot, your bedroom count, and what the county will approve. We source the right tank, handle the permit, and set it correctly under a TCEQ license.

What We Sell and Set

Tank selection is not a catalog exercise

Choosing a septic tank is not about picking a brand. It is about matching the right material, the right capacity, and the right configuration to your site conditions, your OSSF permit requirements, and the system it is part of. We source the tank and set it as part of a complete installation, not as a dropped-and-done delivery.

We work with concrete, fiberglass, and polyethylene tanks. Concrete is the workhorse of residential septic in Texas, heavy, durable, and resistant to flotation in soils with a higher water table. Fiberglass and polyethylene tanks are lighter, which can matter on sites with limited equipment access or when the tank needs to be maneuvered into a constrained space. Each material has legitimate applications and real trade-offs in cost and longevity.

Tank capacity is set by Texas OSSF rules based on bedroom count. We size to code minimums or above them when the site and application warrant more capacity. An undersized tank is a system that will need to be pumped more frequently and is more likely to cause drainfield problems over time.

Tank sales are typically part of a new installation or a replacement project. We do not drop tanks and walk away. The tank is part of the system, and the system needs to be designed, permitted, and installed correctly for the tank to function as intended.

Tank Sales FAQ

Common questions

Concrete is the most common choice in Texas for its durability and resistance to flotation in soils with a higher water table. Fiberglass and polyethylene tanks are lighter, which can make them easier to set on sites with limited equipment access. Each material has legitimate trade-offs in cost, longevity, and site suitability. We help you choose the right material for your conditions, not the one with the highest margin for us.
Tank sizing is determined by the number of bedrooms in the home, which serves as a proxy for occupant count and daily wastewater flow. Texas OSSF rules specify minimum tank capacity requirements for each bedroom count. We size the tank to meet code requirements, and we will tell you if your application warrants going above the minimum.
Installation of a septic tank in Texas must be done by a licensed installer. Separating the tank purchase from the installation creates a coordination problem and distributes responsibility across two parties who may not be aligned. We handle the selection and the installation together, which means one point of contact and one license responsible for the outcome.
Yes. If your current tank has cracked, collapsed, or reached the end of its usable life, we assess the situation, source an appropriate replacement tank, and manage the installation including any required county OSSF permit. See our upgrades and replacements page for more on full system replacement work.
