Water Holding Tanks

Tank Quick Reference Button

These water tanks are suitable for the storage of potable water, freshwater, and wastewater (grey water, black water).

Trionic water and wastewater holding tanks are rotationally molded into durable, seamless, one-piece, non-corrosive tanks. Each tank fully complies with FDA regulation 21 CFR 177.1520 and meets all U.S. Coast Guard regulations. Each Water/Holding tank with fittings has (2) 1-1/2″ FPT and (2) 1/2″ FPT threaded openings. Openings on all tanks feature female National Pipe Threads (NPT) and are located on one end of the tank. Unused openings can be capped. Blank tanks come without any openings or fittings, allowing the user to place fittings at optimal locations for their specific application.

All tanks are 3/8″ average wall thickness.

These tanks are ideal to be used as freshwater holding tanks, wastewater holding tanks, grey water holding tanks, and black water holding tanks. The tanks are commonly installed on boats, yachts, ships, RVs, campers, travel trailers, conversion vans, food trucks, medical vehicles, and for agricultural and horticultural applications.
