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.
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.
The ribbed tanks (600 gallon and larger) need to be kept 1/4 full at all times to prevent floating (rising out of the ground near high water tables) and crushing from soil load. The use of a RainAid Tank Top Up Valve is recommended to maintain the proper water level.
Please note: This tank is very expensive to ship, due to its size and point of origin. Shipping is not included. Please call for freight quote or customer pick-up information.
