Plastic Holding Tanks are usually used for holding fresh water or gray waste water. We offer a 250 gallon rectangular holding tank that is perfect for use in the Portable Toilet business or if you need a holding tank that will fit under most trailers.

Our holding tanks are made from rugged, high density polyethylene. The tanks are molded as single piece, stress-free plastic parts. They are molded in the natural milky-white color of polyethylene or are available in black.

The tanks are made with 4 fittings designed to use clamped hoses or couplings like the Fernco Couplings. There are no threaded or glued fittings that are likely to leak.
