Spherical Cistern Tanks

Manhole extensions and lid/riser combinations are available for instances where it is necessary to bring access to the 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 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.
