Norwesco Underground Water Tanks


Norwesco Below Ground Cistern Water Tanks

Norwesco Underground Water Tanks Selection

Norwesco's underground water tanks (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 Norwesco's water storage tanks, our cisterns are produced with 100% virgin resin which meets FDA specifications for potable water. Where applicable, Norwesco's cisterns have been certified under ANSI/NSF Standard 61.

The 325 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) should be filled one-fourth full after installation.

Manhole extensions and lid/riser combinations are available for instances where it is necessary to bring access to ground level. In addition, Norwesco offers a full range of bulkhead fittings to help adapt the cistern to suit specific needs or applications.

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