Proven in thousands of marine installations, SeaLand holding tanks provide clean, odor-free, and safe service for many years. And with a wide range of capacities and configurations available, there is a SeaLand holding tank to fit virtually any boat.
Featuring top-mounted hose connections and an extra-thick wall of durable polyethylene, SeaLand holding tanks are engineered for odor-free, leak-proof performance.
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 Series of standard holding tanks. HTS-T Series tanks come with integrated discharge pump.
For use exclusively with VacuFlush toilet systems, we offer vacuum holding tanks and holding tanks with built-in vacuum generators.
