360-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 360 Gallon HDLPE Double Wall Containment Tank Opaque Resin - 1.9 specific gravity is designed for farms, ranches, small businesses, and residential properties needing reliable mid-range liquid storage. The 360-gallon capacity hits the sweet spot for EPA-compliant secondary containment — large enough to be genuinely useful, compact enough to install without heavy equipment or specialized foundations.
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 63 inches tall with a 53-inch diameter, requiring 15.3 square feet of level ground. Empty weight is 250 pounds. At full capacity with a 1.9 SG liquid, expect approximately 5,955 pounds on the foundation. Requires a reinforced concrete pad designed for the full loaded weight, with at least 6 inches of compacted gravel sub-base. Place on a firm, level surface free of rocks or sharp objects that could damage the tank bottom. Ensure adequate ventilation if stored chemicals produce vapors.
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. We recommend schedule 80 PVC or polypropylene fittings on the NPT outlet with a ball valve for positive shutoff.
