3,500-gallon white double-wall containment tank built for EPA-compliant secondary containment. Manufactured by Snyder Industries from high-density linear polyethylene (HDLPE) rated to handle liquids up to 15.8 pounds per gallon. Integrated double-wall design provides 110% secondary containment without the cost of a separate containment basin.
The 3500 Gallon Plastic Vertical Double Wall Liquid Chemical Storage Tank in White is designed for commercial operations, agricultural producers, and industrial facilities with serious storage demands. With 3,500 gallons of storage capacity, this tank serves as the backbone of serious EPA-compliant secondary containment operations. It handles the volume demands of commercial and agricultural applications where running out of supply is not an option.
Constructed from high-density linear polyethylene (HDLPE) 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. That extra wall thickness is not optional when you are storing aggressive industrial chemicals. 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 158 inches tall with a 102-inch diameter, requiring 56.7 square feet of level ground. Empty weight is 2500 pounds. At full capacity with a 1.9 SG liquid, expect approximately 57,961 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 18" 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 NPT connections. Full-port ball valves, expansion loops for thermal movement, and proper pipe support are essential at this scale.
Snyder Industries has been a leader in polyethylene tank manufacturing for over 60 years. Their Lincoln, Nebraska facility produces tanks using advanced rotational molding processes with rigorous quality control at every step. Backed by a 3-year manufacturer warranty from Snyder Industries against defects in materials and workmanship under normal use conditions. Certified: 2285,2282. Every tank is inspected before it leaves the production floor — and we inspect it again before it ships from our facility.
