1,335-gallon black storage tank built for heavy-duty industrial chemical containment. Manufactured by Norwesco from virgin linear polyethylene (HDPE) rated to handle liquids up to 15.8 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 1335 Gallon Black Heavy Duty Elliptical Leg Tank is designed for commercial operations, agricultural producers, and industrial facilities with serious storage demands. With 1,335 gallons of storage capacity, this tank serves as the backbone of serious heavy-duty industrial chemical containment operations. It handles the volume demands of commercial and agricultural applications where running out of supply is not an option.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. The 1.9 specific gravity rating means this tank is built with significantly heavier wall sections than a standard water tank — necessary to safely contain liquids weighing up to 15.8 pounds per gallon. That extra wall thickness is not optional when you are storing aggressive industrial chemicals. 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 126 inches long by 66 inches wide and 55 inches tall, requiring 57.8 square feet of level ground. Empty weight is 414 pounds. At full capacity with a 1.9 SG liquid, expect approximately 21,568 pounds on the foundation. Requires an engineered reinforced concrete foundation designed by a structural professional for the full loaded weight. Install on a level, compacted surface. Ensure adequate clearance above for lid access and around the perimeter for plumbing connections and visual inspection.
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. Use schedule 80 PVC or stainless steel bulkhead fittings on the 2" NPT connections. Install a full-port ball valve and consider a Y-strainer to protect downstream equipment.
