With the Roediger® Marina Vacuum Technology, we offer sustainable and flexible complete solutions for the clean and drip-free collection and transport of wastewater generated on boats and ships.


In order to protect coastal waters from pollution, waste water containing faecals from ships may not be discharged untreated into waters according to the European directive, but must be collected and treated in a marina. For this purpose, the marinas are equipped with our evacuation units, which are connected to a vacuum system via a pipeline network.

The evacuation units are firmly installed on the dock or mooring location. A flexible suction hose makes it possible to reach several boats within an approx. 9 meter (30 foot) circle around the evacuation unit. Once the boat is docked, the hose is connected to the holding tank of the boat and the odor and spill free evacuation process begins.

Aqseptence also supplies products for the removal of bilge water. This oily wastewater is evacuated separately from the wastewater, then transferred to a local light fluid separator for oil and petrol and finally discharged back into the sewer system. Combining our marina technology with a vacuum sewer system is particularly attractive for the customer when several boat evacuation units are planned.

Additional cost savings and benefits can be attained when a vacuum sewer system is also connecting surrounding buildings in the marina (such as bars, restaurants, sanitary facilities and marina management).
