500-gallon liquid storage tank built for agricultural chemical and fertilizer storage. Manufactured by Chemtainer from virgin linear polyethylene (HDPE) rated to handle liquids up to 12.5 pounds per gallon. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler.
The 500 Gallon Plastic Vertical Liquid Storage Tank is designed for farms, ranches, small businesses, and residential properties needing reliable mid-range liquid storage. The 500-gallon capacity hits the sweet spot for agricultural chemical and fertilizer 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 to 1.5 specific gravity, this tank handles liquids up to 12.5 pounds per gallon — covering the full range of agricultural chemicals, liquid fertilizers, and most industrial solutions. The wall thickness is engineered specifically for this density range. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler. UV stabilizers are compounded directly into the resin — not a surface coating — for outdoor service life that lasts the full warranty period and beyond.
This tank measures 53 inches tall with a 63-inch diameter, requiring 21.6 square feet of level ground. Empty weight is 110 pounds. At full capacity with a 1.5 SG liquid, expect approximately 6,365 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" 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" 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.
Chem-Tainer Industries has manufactured chemical-resistant polyethylene tanks in the USA since 1957. Their tanks are specifically engineered for chemical storage applications with wall thicknesses and resin formulations matched to the demands of aggressive chemicals.
