Engineered for odor-free, leak-proof performance, SeaLand holding tanks provide clean and safe service for many years. With a wide range of capacities and configurations available, there is a SeaLand holding tank to fit virtually any boat.
All SeaLand holding tanks feature top-mounted hose connections and extra-thick polyethylene construction. Our DHT-L Series of standard tanks is available in five capacities with pre-assembled fittings. For more flexibility in fitting placement and choice of configurations and sizes, check out the HTS-Basic Series of standard holding tanks. HTS-T Series tanks come with integrated discharge pump.
Complete your holding tank system with a waste discharge pump and discharge controls, tank monitor system, and vent filter. Refer to this marine toilet system illustration that shows the different components and installation of a typical holding tank system.
For use exclusively with VacuFlush toilet systems, we offer vacuum holding tanks and holding tanks with built-in vacuum generators.
