Norwesco's below-ground water cisterns feature the same rugged, ribbed design found in our Legacy septic tanks and are lightweight for ease of transport and installation. Our cisterns are ideal for instances when drinking water must be hauled in or if a well does not meet consumption needs. Norwesco cisterns are manufactured using resins that meet FDA specifications to ensure safe storage of potable water. Where applicable, Norwesco's cisterns have been certified under ANSI/NSF Standard 61.
Manhole extensions and lid/riser combinations are available for instances where it is necessary to bring access to ground level. In addition, a full range of bulkhead fittings to help adapt the cistern to suit specific needs or applications available.
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 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.
