Septic Tank Replacement in Midlothian, TX

Sometimes the drain field is fine and it is the tank itself that has failed. A cracked concrete tank, a collapsed baffle wall, a rusted-out steel tank, or a tank too small for an expanded house can all be replaced without tearing out the entire system. Knowing the difference between a tank replacement and a full system rebuild is the difference between a few thousand dollars and five figures.

Signs the tank, not the field, is the problem

• Groundwater leaking in, or effluent leaking out at the tank
• A collapsed or crumbling concrete lid or wall
• An old steel tank that has rusted through
• A tank undersized for a remodeled or added-on home

What replacement involves

Confirming the tank is the fault, pumping and removing the old tank, setting a correctly sized new tank, reconnecting the inlet and outlet, and passing inspection. Older Ellis County properties sometimes still have steel or single-compartment tanks well past their life. Replacing one before it collapses avoids an emergency and protects a drain field that may still have years left.

Frequently asked questions

Can I replace just the tank and keep my drain field?

Often yes, if the field is still functioning. That is exactly when a tank-only replacement makes sense.

How much is a septic tank replacement?

Typically $3,500 to $9,500 depending on size and access, well below a full system install.
