Polyethylene Septic Tanks

Polyethylene (Plastic) Septic Tanks are designed and manufactured with rigorous quality controls to meet wastewater treatment system standards. The trapezoidal, deep rib design and exclusive interior divider system make these tanks the industry choice for strength and durability. The exclusive, custom-molded gasket system locks lids firm for a water-tight seal.

Ace Roto-Mold Tanks are stronger, easier to install and less costly than old-fashioned concrete septic tanks - yet they still offer the quality construction and safety you expect. Manufactured from high-density polyethylene with U.V. inhibitors, Ace Roto-Mold tanks utilize a horizontal flow designed for below ground installations up to 36 inches. Ace Roto-Mold Tanks are IAPMO approved and have passed strenuous stress tests. Each tank carries an individual serial code and is fully documented from date of manufacture.

- Withstands up to 500 PSF load pressure
- Exclusive deep rib design
- Unique locking/gasket lid design
