Manufactured by Norwesco from virgin linear polyethylene (HDPE) rated to handle liquids up to 15.8 pounds per gallon. FDA approved for contact with potable water, ensuring safe storage for drinking water and food-grade liquids.
The 1450 Gallon Underground Water Storage Cistern Tank is designed for commercial operations, agricultural producers, and industrial facilities with serious storage demands. It handles the volume demands of commercial and agricultural applications where running out of supply is not an option.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. The 1.9 specific gravity rating means this tank is built with significantly heavier wall sections than a standard water tank — necessary to safely contain liquids weighing up to 15.8 pounds per gallon. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler. Maximum operating temperature is 130 F / 54 C, with UV stabilizers compounded directly into the resin for outdoor service life.
This tank measures 157 inches long by 60 inches wide and 51 inches tall, requiring 65.4 square feet of level ground. Empty weight is 384 pounds. At full capacity with a 1.9 SG liquid, expect approximately 23,361 pounds on the foundation. Requires an engineered reinforced concrete foundation designed by a structural professional for the full loaded weight. Install on a level, compacted surface. Ensure adequate clearance above for lid access and around the perimeter for plumbing connections and visual inspection.
This tank ships without pre-installed fittings, giving you full flexibility to position inlet and outlet connections exactly where your plumbing layout requires. Use polyethylene-compatible bulkhead fittings for all penetrations. The 20" lid opening provides ample access for interior inspection, cleaning, and installation of float switches, level sensors, or submersible pumps. Use schedule 80 PVC or stainless steel bulkhead fittings on the NPT connections. Install a full-port ball valve and consider a Y-strainer to protect downstream equipment.
