Types of Septic Systems We Install

We tailor every installation to fit your property and needs:

Conventional Septic Systems

Standard tank and drain field systems for properties with suitable soil and sufficient space.

Aerobic Septic Systems

Advanced treatment units for smaller lots, poor soil, or high water tables. These systems use oxygen to break down waste more effectively and often include a spray or drip dispersal system.

Pump Systems

When gravity alone isn’t enough, we install pump-assisted septic systems to ensure proper flow from the tank to the drain field.

FAQs – Septic Installation in Magnolia, TX

  • How long does septic installation take?

    Once permits are approved, most installs take 2–4 days depending on system type and site conditions.


  • Do I need a permit for septic installation?

    Yes. We handle all required permits, site planning, and scheduling of inspections.


  • What’s the difference between aerobic and conventional systems?

    Conventional systems use gravity and soil absorption to treat wastewater. Aerobic systems use oxygen to accelerate treatment and are often required on small or poor-draining lots.
