Whale Grey Waste Tanks w/Intelligent Control

The Whale Grey Waste Tanks with Intelligent Control is a compact, multi-port grey water holding tank engineered for modern marine vessels. This one-piece polyethylene tank integrates intelligent level monitoring and control, allowing operators to manage grey waste capacity from a single through-hull fitting rather than multiple installations. Built by Whale Marine, a recognized leader in marine sanitation systems, this tank combines practical efficiency with proven reliability in saltwater and freshwater environments.

The robust polyethylene construction is designed to withstand the corrosive effects of salt spray and the mechanical stresses of boat operation. The tank's compact footprint—11 x 10 x 20 inches at 9 lbs—fits tight engine compartments and cabin spaces where larger systems would be impractical. Multi-port configuration options allow flexible installation depending on your vessel's layout and plumbing requirements. The intelligent control system provides real-time waste level visibility, eliminating guesswork about tank capacity and enabling preventive pump-out scheduling before overflow occurs.

This tank is optimized for use with Whale Gulper Grey Waste pumps, which are known for handling debris-laden waste streams without clogging—a critical feature on vessels where grey water contains food particles, soap residue, and other solids. Weekend cruisers and serious offshore operators alike benefit from the simplified system approach: consolidating multiple tank functions into a single intelligent unit reduces maintenance points, simplifies troubleshooting, and frees up valuable storage space. The design meets the needs of operators who prioritize reliability in remote waters where pump failures and plumbing complications are costly and inconvenient.
