100-gallon natural white storage tank built for agricultural chemical and fertilizer storage. Manufactured by Norwesco from virgin linear polyethylene (HDPE) rated to handle liquids up to 12.5 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 100 Gallon Utility Tank is designed for homeowners, hobbyists, small farms, and mobile applications where compact size matters. At 100 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. Maximum operating temperature is 120° F / 48° C, with UV stabilizers compounded directly into the resin for outdoor service life.
This tank measures 38 inches long by 26 inches wide and 26 inches tall, requiring 6.9 square feet of level ground. Empty weight is 50 pounds. At full capacity with a 1.5 SG liquid, expect approximately 1,301 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 1" 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 8" Threaded Vented Lid 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.
