4,000-gallon white water storage tank built for residential and commercial water storage. Manufactured by Chemtainer from virgin linear polyethylene (HDPE) rated to handle liquids up to 8.3 pounds per gallon. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler.
The 4000 Gallon ChemTainer Plastic Water Storage Tank in White is designed for commercial operations, agricultural producers, and industrial facilities with serious storage demands. With 4,000 gallons of storage capacity, this tank serves as the backbone of serious residential and commercial water storage operations. 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. Rated for liquids at 1.0 specific gravity (8.3 pounds per gallon), this tank is optimized for water storage with wall thickness calibrated for standard water weight. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler. Maximum operating temperature is 120 F/ 48 C, with UV stabilizers compounded directly into the resin for outdoor service life.
This tank measures 125 inches tall with a 102-inch diameter, requiring 56.7 square feet of level ground. Empty weight is 550 pounds. At full capacity with a 1.0 SG liquid, expect approximately 33,910 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.
Factory-installed fittings include a 2" outlet and a 1.5" inlet, both with NPT threading for direct connection to standard schedule 40 or schedule 80 PVC, polypropylene, or stainless steel plumbing. The 16"" lid opening provides ample access for interior inspection, cleaning, and installation of float switches, level sensors, or submersible pumps. Install schedule 80 PVC or stainless steel piping on all 2" NPT connections. Full-port ball valves, expansion loops for thermal movement, and proper pipe support are essential at this scale.
