330-gallon black storage tank built for safe potable water storage. Manufactured by Bushman from virgin linear polyethylene (HDPE) rated to handle liquids up to 8.3 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 330 Gallon Black Vertical Water Storage Tank is designed for farms, ranches, small businesses, and residential properties needing reliable mid-range liquid storage. The 330-gallon capacity hits the sweet spot for safe potable water storage — large enough to be genuinely useful, compact enough to install without heavy equipment or specialized foundations.
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. 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 63 inches tall with a 41-inch diameter, requiring 9.2 square feet of level ground. Empty weight is 75 pounds. At full capacity with a 1.0 SG liquid, expect approximately 2,827 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.
Factory-installed fittings include a 2" PP Female NPT Bulkhead Fitting outlet and a 2" PP Female NPT Bulkhead Fitting inlet, both with NPT threading for direct connection to standard schedule 40 or schedule 80 PVC, polypropylene, or stainless steel plumbing. The 12" 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 2" NPT outlet with a ball valve for positive shutoff.
