  • Low-Profile Design - Makes for less excavating and easier installation of the septic tank. No special backfill or filling with water during installation is required, which saves time.
  • IAPMO Listed - Most counties and states require the stamp of approval from the International Association of Plumbing and Mechanical Officials on septic tanks before they can be installed.
  • Warranties - Fiberglass septic tanks: 5 years; Poly septic tanks: 3 or 5 years depending on model

Advantages of Polyethylene & Fiberglass Septic Tanks

  • Easy Installation - No heavy equipment is needed to transport or install our septic tanks. This is a valuable advantage in rough or inaccessible areas and in wet weather conditions.
  • Durability - Polyethylene, because of its excellent corrosion resistance and chemical compatibility is the ideal material for on-site applications.
  • Non-Porous Material - Roots will not penetrate poly septic tanks and fiberglass septic tanks as they can with concrete septic tanks.
  • Easy to Repair - If damaged, poly and fiberglass septic tanks can be repaired easier than concrete or steel septic tanks.
