about recreational vehicle septic tanks

Black Water RV Tanks are designed specifically for the collection of wastewater from toilets in RVs, motorhomes, 5th wheels, trailers, campers, and tiny houses. RV black water tanks are designated explicitly for the septic purpose of holding sewage wastewater and are not recommended for any other use.

These blackwater tanks are made from rotationally-molded polyethylene resin that provides strength, long service life, and great protection against cracks, rust, and corrosion. Blackwater holding tanks are manufactured by Dura-Cast and Ronco.

RV septic tanks can be used for most recreational vehicles makes and models. They can be used as a new or replacement black water tank. The septic tanks are available with pre-installed fittings or as blank tanks with DIY custom fitting packages. Capacities for black water tanks range in 5 gallon to 202 gallons, with tank thickness ranges from 0.25 inches (1/4") to 0.375 inches (3/8"). When installing or performing maintenance, all care, handling, and procedures should be done specifically for wastewater holding tanks.
