Marine Holding Tanks

Our marine holding tanks are extremely strong and sturdy. They are manufactured using rotomold technology, which means that this marine waste holding tank has 3/8” thick walls and is nearly unbreakable. It has no seams, which means there’s less opportunity to break or leak. Fittings are spin-welded to ensure secure, leak-proof connections. These marine black water holding tanks comply with FDA and Coast Guard standards. Simply indicate on the tank drawing where you’d like your fittings placed!
