Boat Water Tanks

Our boat water tanks are available from 240 to 1000 litres for drinking water, wastewater and where space is an issue.  Our boat water storage tanks are rotationally moulded from virgin, high-quality polyethene and available in flat, horizontal or upright orientations.
Our drinking water and wastewater boat storage tanks are available in 240, 400, 500, 800, 1000 litre sizes and are stocked for quick delivery.  These one-piece moulded MDPE water tanks are potable drinking water in black which means these are taste and taint free.  In natural these are made from food-grade level material and the level can be seen from outside the tank for easy level checking. The tank can be easily cleaned as it has a lid on the top and an outlet for draining the contents.

Additional Outlets For Boat Tanks

These boat tanks are available addition welded socket outlets and can be customised to the fittings you need for your water pump or system.  Connection kits are available for interlinking tanks if required.

Customised Boat Tanks

If the moulded tank size you are looking for isn’t listed, we can build bespoke plastic water and wastewater tanks.  These are built to order for boats, marine yachts and narrowboats.
