1,635-gallon black horizontal leg 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. FDA approved for contact with potable water, ensuring safe storage for drinking water and food-grade liquids.
The 1635 Gallon Horizontal Elliptical Leg Tank in Black is designed for commercial operations, agricultural producers, and industrial facilities with serious storage demands. This 1,635-gallon horizontal configuration keeps the center of gravity low, making it ideal for transport applications or stationary installations where height clearance is limited. The horizontal profile also works well for gravity-feed systems and low-profile installations.
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. 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 142 inches long by 71 inches wide and 58 inches tall, requiring 70.0 square feet of level ground. Empty weight is 465 pounds. At full capacity with a 1.5 SG liquid, expect approximately 20,919 pounds on the foundation. Requires an engineered reinforced concrete foundation designed by a structural professional for the full loaded weight. Horizontal tanks must be supported by saddles or cradles rated for the full loaded weight. Never use narrow supports that create point loads on the tank wall.
Comes equipped with a 2" fitting with 2" siphon 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. 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.
Norwesco is the largest manufacturer of rotationally molded poly tanks in North America, operating over 20 manufacturing plants across the U.S. and Canada. Every tank is produced from proprietary resin formulations and backed by decades of rotomolding expertise. Backed by a 3-year manufacturer warranty from Norwesco against defects in materials and workmanship under normal use conditions. FDA approved for contact with potable water and food-grade liquids. Every tank is inspected before it leaves the production floor — and we inspect it again before it ships from our facility.
