RomoTech 50-Gallon Horizontal Square Water Tank Natural Translucent — UV-Resistant, 5.5in Lid

RomoTech's 50-gallon horizontal square reservoir is a UV-stabilized polyethylene water tank made in the USA for storing and transporting non-flammable liquids with built-in level markings and a 3/4" NPT drain.

Built by rotational molding in Indiana from medium-density polyethylene, this compact square-profile tank combines clear level visibility with weather-resistant construction. The natural translucent walls let you monitor contents at a glance while molded gallon and liter graduations provide accurate measurements. Designed for outdoor and mobile use, it resists rust and UV damage and includes fill, drain, and tie-down features that suit agricultural, recreational, and light industrial needs.

How does this tank make filling and emptying fast and simple?

The tank includes an oversized 5-1/2" lid (5" opening) to speed pouring and cleaning, paired with an easy-tighten cap to reduce spills. A factory-installed bulkhead fitting with a 3/4" NPT outlet accepts common hose and pump connections for quick draining, siphoning, or pressure-washer hookups.

• 5-1/2" lid (5" usable opening) for fast refills and access
• Easy-tighten cap to minimize leaks during transport
• Built-in 3/4" NPT bulkhead for standard hoses and pumps
• Molded gallon/liter markings for precise volume control

Will it survive outdoor use on a truck or trailer?

Yes — the tank’s medium-density polyethylene is UV-stabilized to resist fading, warping, and cracking from sun exposure. Molded tie-down channels accept saddle straps so the tank secures firmly in a truck bed or on a trailer for mobile applications.

• UV-resistant resin for prolonged outdoor life
• Molded tie-down channels for secure transport
• Square profile minimizes rolling and maximizes footprint efficiency
• Non-corroding plastic outlasts metal tanks in wet conditions

Is this tank suitable for potable water and other liquids?
