340-gallon beige storage tank built for safe potable water storage. Manufactured by Enduraplas from virgin linear polyethylene (HDPE) rated to handle liquids up to 9.2 pounds per gallon. FDA approved for contact with potable water, ensuring safe storage for drinking water and food-grade liquids.
The 340 Gallon Beige Vertical Water Storage Tank is designed for farms, ranches, small businesses, and residential properties needing reliable mid-range liquid storage. The 340-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. With a 1.1 specific gravity rating, this tank handles liquids up to 9.2 pounds per gallon, which covers water and most common liquid storage applications. 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 74 inches tall with a 40-inch diameter, requiring 8.7 square feet of level ground. Empty weight is 75 pounds. At full capacity with a 1.1 SG liquid, expect approximately 3,194 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.
Comes equipped with a 2" PP Female NPT Bulkhead Fitting NPT outlet fitting installed at the factory. No inlet fitting is included — drill and install a bulkhead fitting at your preferred height for your specific plumbing layout. The 16" Threaded Vented Manway 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 2" NPT outlet with a ball valve for positive shutoff.
