Holding tanks are an indispensable component of modern on-board toilet systems – especially on longer trips or in waters where waste disposal is mandatory. They ensure safe and environmentally friendly storage of wastewater. In the awn online shop, you'll find suitable holding tanks for every boat size.
Holding tanks are used for the clean, temporary storage of black water from on-board toilets. They prevent direct discharge into the waterway, thus making an important contribution to environmental protection. The tanks are made of robust, odor-proof plastic and can be used at sea and in port.
Various sizes and designs
Whether compact for smaller boats or large-capacity for yachts, our holding tanks are available in numerous sizes and shapes. Many models are equipped with multiple connections, allowing them to be flexibly integrated into existing plumbing systems.
With ventilation and inspection opening
For odor-free and hygienic handling, many wastewater tanks feature integrated vents and cleaning openings. This simplifies maintenance and ensures reliable operation – even under intensive use.
Accessories for waste water tanks
Our range also includes matching accessories such as vent filters, tank gauges, deck fittings, pumps, and hose connectors. This allows you to optimally equip your on-board toilet and ensure maximum functionality and comfort on board.
