Marina Systems

For marinas alongside rivers, lakes or seas, Bilfinger Water Technologies offers all-in-one solutions for the evacuation of wastewater from boats and ships. In addition, with its ROEDIGER® and AIRVAC® vacuum sewer technology Bilfinger meets the highest hygienic requirements for the removal of wastewater from marina settlements.

Smaller and medium-sized ships are equipped with collection tanks for toilet and wastewater. According to European and American Directives the wastewater must be collected and treated in the marina before it is discharged into the ocean. For this purpose, ROEDIGER® and AIRVAC® evacuation panels, which are connected to a vacuum station via a pipeline network, are installed.

The evacuation units are firmly installed on the jetty or swimming pontoon. A flexible suction hose makes it possible to reach several boats within an approx. 5 foot (15 m) circle around the evacuation unit. During the odor- and spill-free evacuation process the hose is connected to the holding tank of the boat. 

Bilfinger Water Technologies GmbH also supplies product for the removal of bilge water. This oily wastewater is evacuated separately, then separated in a local light fluid separator from oil and petrol and finally discharged back into the sewer system. Combining ROEDIGER® and AIRVAC® marina technology with the vacuum sewer system is particularly attractive for the customer when several boat evacuation units are planned. Cost savings are additional benefits associated with  connecting a vacuum sewer system to surrounding buildings in the marina (such as bars, restaurants, sanitary facilities and marina management).
