The grey discharge water is collected inside the tank located in the technical room.
The tank collects the discharge water from sinks and shower’s bathroom; it also collects the condense water of the air conditioning system fan-coil. The tank, not being airtight, does not need any air vent.
The pump power supply magneto-thermal switch is located on the main control panel, together with a warning light that signals its operation.
The pump is automatically controlled by an electronic level switch installed inside the tank. The grey water pump starts when the sensor detects a high water level and deactivates once the water level has lowered. The system is equipped with a timer which delays useless pump start ups due to yacht’s roll.
The galley’s basin discharges directly overboard, without any pump, through the outboard discharge located below the basin itself. The cockpit’s sink and ice-maker also discharge directly overboard, on the port side.
The system can be approved for use on Swiss lakes by channelling waste water from the kitchen sink and the cockpit sink into a greywater collection tank (which normally discharging directly overboard).
The system is equipped with suitable solenoid valves that interlace the taps, in case the collection box is full. The system is provided with a system that allows the suction of gray water from the platform.
Sea discharges are blocked in the case of type-approval for navigation on Swiss lakes.
ENVIRONMENTAccording to the regulations in force for navigation on Swiss lakes, grey water must be discharged exclusively by suction from the shore, through a special outlet, after activating the three way valve located in the technical room, following the instructions on the special label.
