Marine Black Water Holding Tanks

Marine black water tanks are used for holding sewage wastewater from toilets. Made from strong, rotationally-molded polyethylene resin, these tanks offer long service life, protection from rust, and durability against corrosion and impact.

Boat septic tanks are manufactured by Ronco and Dura-Cast in a wide range of fluid capacities, product dimensions, and wall thicknesses. Numerous tank specifications are available to provide the correct installation for a precise make and model of marine vessels. These marine waste holding tanks can be used as new or replacement blackwater tanks.

Capacities for marine black water tanks are rated from 5 gallons to 202 gallons. Various wall thickness are available, measuring from 0.1875 inches (3/16") to 0.375 inches (3/8"). Marine waste tanks come rectangular in shape or are custom-molded to match a particular model style of boat. The tanks are offered with fittings pre-installed or as blanks with DIY fitting packages.

Care should be exercised to ensure proper installation and that all applications and maintenance are performed to the specifics required for marine black water tanks.
