The spherical tanks from Norwesco may remain in the ground when empty. These tanks include a molded-in elevated pump stand on the bottom of the tank.

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.
