5.5 Fresh and waste water systems

Your boat can be equipped with a fresh water system and a waste water system. Depending on your choice of equipment, the waste water system can consist of separate grey water and black water systems.

The fresh, grey and black water systems have each their own plumbing and tanks.

  • The fresh water system provides water to the shower on the bathing platform, to the bidet shower in the toilet compartment, and to the taps in the wet bar and in the toilet compartment.

  • The grey water system collects waste water from the sinks in the toilet compartment and wet bar. In addition, the grey water system collects the condensation water from the optional air conditioning equipment.

    • The grey water runs from the sinks to the holding tanks below the sinks. To ensure the grey water system keeps working properly, use the Grey water pump button on the toilet compartment control panel or on the side terrace control panel regularly to pump the grey water from the holding tanks to the separate grey water tank.

  • The black water system collects the waste water from the toilet.

  • The toilet operates with electricity or manually, depending on your choice of equipment. The electrical toilet uses fresh water for flushing, and the manual toilet uses sea water or lake water for flushing.

When you leave the boat unused for a longer period of time or store the boat over winter, the fresh and waste water systems will build up bacteria and impurities, or will freeze in cold weather. Before you leave or store your boat, empty the fresh and waste water systems and tanks and flush them with fresh water.
