Septic Tanks

Ace Roto-Mold septic tanks are stronger, easier to install, and more cost-efficient than old-fashioned concrete septic tanks. Manufactured from HDPE with UV inhibitors, Ace Roto-Mold tanks utilize a horizontal flow designed for below-ground installations up to 36 inches. Each tank carries an individual serial code and is fully documented from the date of manufacture. Ace Roto-Mold septic tanks are designed and manufactured with rigorous quality controls. The trapezoidal deep-rib design and interior baffle system make Ace Tanks the industry choice. Only Ace tanks feature a custom-molded gasket in the lid. Manufactured from extruded nitrile rubber, the gasket snaps into the lid to ensure a watertight seal. Our exclusive lid design locks in place with nylon ties, eliminating the need for metal fasteners that can corrode and fail. Ace's unique tank baffle system slows the wastewater flow and directs it to the middle of the tank so wastewater can separate from solids. An outlet baffle allows the partially treated liquids to flow out for further treatment. Advantages of Ace's baffle design include added strength, versatility, and ease of installation. Septic tanks are available in one-compartment and two-compartment designs and are manufactured for the containment of liquids up to 1.7 specific gravity. These tanks are designed and manufactured to meet wastewater treatment system standards. The primary function of the septic tank is to collect household wastewater, which includes water from the toilet, referred to as black water, and water from the bathtub, showers, sinks, and laundry, collectively called gray water. The septic tank treats the wastewater naturally by holding it in the tank long enough for the solids and liquids to separate.
