Below Ground Cistern Tanks - Below-ground water cisterns feature the same rugged, ribbed design found in our septic tanks. Our cisterns are ideal for instances when drinking water must be hauled in or if a well just doesn't meet consumption needs. As with all of our water storage tanks, our cisterns are produced with 100% virgin resin which meets FDA specifications for potable water. Where applicable, cisterns have been certified under ANSI/NSF Standard 61.

The 300 and 550 gallon spheres may remain in the ground when empty. These tanks include a molded-in elevated pump stand on the bottom of the tank. The ribbed tanks (600 gallon and larger) need to be kept 1/4 full at all times.

Manhole extensions and lid/riser combinations are available for instances where it is necessary to bring access to ground level. In addition, we offer a full range of bulkhead fittings to help adapt the cistern to suit specific needs or applications. (See above ground tank accessories.)

All 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 the tanks will not rust or corrode and require no additional coatings as other tanks do. Strict quality guidelines ensure an environmentally safe cistern tank.
