Ace Roto-Mold cistern single compartment tanks are intended for bulk storage or collection of potable water and designed for below ground level installations. These tanks are manufactured from high-density polyethylene with U.V. inhibitors and feature a trapezoidal, deep rib design. Manufactured from extruded Nitrile rubber, the gasket snaps into the lid and ensures a watertight seal. The exclusive lid design locks in place with nylon ties, eliminating the need for metal fasteners that can corrode and fail. Ace Roto-Mold cistern tanks are FDA-approved for potable water and are manufactured for containment of liquids up to 1.7 specific gravity.
