1800 Gallon Horizontal Leg Tank – Dual Tank Assembly

The Norwesco 42990 1800 Gallon Horizontal Leg Tank is a twin-tank configuration consisting of two 900-gallon tanks butted together and designed for high-capacity liquid transport and storage. Constructed from durable, rotationally molded polyethylene, the tank provides exceptional impact resistance, long life, and superior UV protection for demanding outdoor applications.

This tank includes dual 2" female NPT bulkhead fittings—one on each tank end—with siphon tubes. As a two-tank assembly, each tank section must be plumbed separately. Molded legs act as internal baffles to reduce liquid sloshing, improving transport stability. The tank is FDA-compliant, NSF-61 certified, and suitable for potable water and a wide range of agricultural and commercial liquids.
