Septic System Installation in Ascension Parish

We are certified and endorsed in the installation of residential sewers across Louisiana. Our residential install is an AWT poly MO-DAD 1 treatment plant: 600 gallons per day, 750-gallon capacity, rated for homes up to four bedrooms.

The starting price is $4,000, and it includes the tank, the aerator, all of your paperwork, and 100 feet of discharge line. The tank is polypropylene and carries a lifetime warranty.

What the state requires

Louisiana regulates home sewage systems by bedroom count: a 600-gallon-per-day plant covers up to a four-bedroom home, and five or more bedrooms step up to a larger tank. We size the system to the house, handle the permitting paperwork, and install it to spec.

What the install includes

  • MO-DAD 1 polypropylene treatment plant — lifetime tank warranty
  • Aerator, fitted and running before we leave
  • All permitting and paperwork, handled for you
  • 100 feet of discharge line
  • The excavation, done by our own crew and equipment

Replacing an old tank

If you are replacing a failed system, the practical route is to pump the old tank down, take it out of service in place, and set the new system — pulling a decades-old tank out of the ground creates a hazardous mess that landfills will not take. We will walk you through exactly what your site needs.

Where we work

Based in St. Amant, LA, serving Ascension Parish including Gonzales, Prairieville, Geismar, Sorrento and Donaldsonville, plus Livingston Parish (Denham Springs, Walker, French Settlement, Maurepas) and the Baton Rouge area — roughly a 45-minute radius from home base.
