150-gallon black double-wall containment tank built for EPA-compliant secondary containment. Manufactured by Snyder from high-density linear polyethylene (HDLPE) rated to handle liquids up to 15.8 pounds per gallon. Dual FDA and NSF 61 certified — one of the few tanks approved for both potable water and food-grade liquid storage.
The 150 Gallon ASTM HDPE Black Double Wall Tank is designed for farms, ranches, small businesses, and residential properties needing reliable mid-range liquid storage. The 150-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. UV-resistant black pigmentation provides maximum outdoor durability and inhibits algae growth in stored liquids. Maximum operating temperature is 120° F / 48° C, with UV stabilizers compounded directly into the resin for outdoor service life.
This tank measures 62 inches tall with a 34-inch diameter, requiring 6.3 square feet of level ground. Empty weight is 110 pounds. At full capacity with a 1.9 SG liquid, expect approximately 2,487 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 14" Threaded Vented Lid lid accommodates fill lines, vent connections, and basic interior access for inspection. We recommend schedule 80 PVC or polypropylene fittings on the NPT outlet with a ball valve for positive shutoff.
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 against defects in materials and workmanship under normal use conditions. FDA approved for contact with potable water and food-grade liquids. NSF/ANSI 61 certified for potable water system components. Every tank is inspected before it leaves the production floor — and we inspect it again before it ships from our facility.
