Efficient and safe rotomoulded marine holding tank

The marine holding tank is the answer to the challenges of boats in terms of waste management and safe storage and emptying. As well as other rotomoulded boats components the tank is made of polyethylene and is extremely durable, resistant to breakage, mechanical damage and corrosion.

Polyethylene is a material that is particularly resistant to harmful chemicals, making tanks made from it ideal for storing various types of sewage and waste. A key benefit of the waste holding marine tanks manufactured at Rotovia is that they are certified in accordance with EN ISO 8099-1:2018, a European standard for the water tightness and mechanical strength of boat sewage tanks. This standard ensures that our tanks are manufactured to the highest quality and safety standards.

Rotational moulding technology allows the production of both marine holding tanks and water tanks in a variety of shapes and sizes so that the product can be perfectly tailored to specific boats. By manufacturing the tank in one piece, it is free of welds and joints, providing a perfect seal and guaranteeing that the contents of the tank will not leak outside. Marine holding tanks are fitted with special valves so that wastewater is safely stored and can be easily drained when required.

Marine waste holding tank system for wall and bottom mounting

A significant benefit of holding tanks for marine is their stable construction, while at the same time being lightweight, which is of great importance during tank transport, storage and installation.

Waste holding tanks for marine can be mounted in two ways: on the bottom or the wall. This provides maximum flexibility and ensures that a solution is found that best suits specific boats, ships or other vessels. For example, if space is limited, wall-mounted tanks may be the ideal solution, while bull bottom tanks may be more suitable for larger boats or areas with more space.

The use of a marine waste holding tank system manufactured using rotomoulding technology not only ensures that waste is safely stored, but also has a strong environmental benefit, as the polyethylene from which the tanks are made is an environmentally friendly, biodegradable and recyclable material.
