Engineered for durability and consistent performance, the RomoTech 26 Gallon Horizontal Square Water Tank is a professional-grade solution for storing non-flammable liquids. Manufactured in the USA using high-quality medium-density polyethylene, this tank is built to withstand rigorous daily use in agricultural, industrial, and mobile applications. The rotational molding process ensures a seamless, rugged construction that resists rust, corrosion, and the damaging effects of UV exposure, making it an ideal choice for long-term outdoor storage on farms, work sites, or utility trailers.
Designed with the operator in mind, the tank features convenient molded gallon and liter markings, allowing for quick and accurate fluid level verification at a glance. Refilling and dispensing are streamlined by the oversized 5-1/2″ lid—which provides a generous 5″ opening—and the integrated bulkhead fitting with a 3/4″ NPT outlet. Whether you are setting up a mobile detailing rig, an irrigation system, or emergency water storage, the tank’s integrated tie-down channels allow for secure mounting to truck beds or trailers using saddle straps, ensuring stability during transport.
