All of our cistern tanks are manufactured by means of the rotational molding process, which produces a one-piece, seamless, watertight tank. Polyethylene is unaffected by soil chemicals so our tanks will not rust or corrode.

As with all of our water storage tanks, our cisterns are produced with 100% virgin polyethylene resin which meets FDA specifications for potable water.
The optional manhole extension is available for instances where it is necessary to bring access to ground level.
Integral columns in the tank give it excellent structural strength.
