Marine Fresh Water Tank

Marine water tanks are designed to store potable water in boats and vessels equipped with plumbing such as yachts, sailboats, or deep sea fishing boats. Our tanks are made with FDA-approved, virgin polyethylene plastic resins. The one-piece marine holding tank design ensures tank longevity and durability. Our roto-mold, seamless tanks do not crack or weaken with time, making them cost effective and eco-friendly. Marine water tanks are available in a bow, rectangle or wedge shaped design with a wide selection of sizes and capacities.

Our tanks are a blank canvas, allowing us to customize tanks to your exact specifications. Rotate your tank any way you need to fit your unique requirements. All of our tanks have female NPT openings in the same position on one end, so they are suitable for all marine plumbing needs. You can easily drain water from all of our tanks, preventing damage from freezing temperatures during the off-season. We offer custom marine fresh water tanks and spin-welded fittings for the unique size and fit of the tank you need. Choose One Clarion for the highest quality marine tanks on the market!

Our marine holding tank is made using a roto molding process that melts the virgin polyethylene resin inside a hollow, closed mold. The cast is heated to 260°C – 370°C, allowing the resin to evenly coat the mold. This unique plastic tank fabrication creates a one-piece, watertight tank that is perfect for marine fresh water or graywater tanks. The walls have an even thickness making them more durable and preventing water contamination.
