70-gallon portable utility 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 70 Gallon Plastic Portable Utility Tank is designed for homeowners, hobbyists, small farms, and mobile applications where compact size matters. At 70 gallons, this is the kind of tank you keep close at hand — on the workbench, mounted to equipment, or tucked in a utility closet. It is compact enough to place anywhere but built to the same standards as tanks ten times its size.
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 42 inches long by 26 inches wide and 18 inches tall, requiring 7.6 square feet of level ground. Empty weight is 40 pounds. At full capacity with a 1.5 SG liquid, expect approximately 916 pounds on the foundation. Set on a flat, level pad of compacted gravel or a concrete slab at least 4 inches thick. 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 0.75" 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 8" lid accommodates fill lines, vent connections, and basic interior access for inspection. Standard garden hose adapter or direct NPT connection works well for tanks this size.
