The Sanitation Tank and Pump System

The original toilet was an outboard discharge type via a 240v electric macerator unit. This toilet was housed in a cubicle in a corner of the galley!!! The plan was always to have a full bathroom, so obviously the toilet would be housed in there.

The necessity in order to get a BSC and be able to cruise non-tidal inland waterways was to fit a sewage holding tank.

The location I decided to install this tank was under the saloon floor, directly forward of the rear saloon bulkhead, adjacent the room that was to become the bathroom. Although I was unable to install the fresh water tanks under the saloon floor, the location chosen for the sewage holding tank proved more successful.

The requirement for the BSC, and for inland cruising, is for an enclosed pump-out system to be installed. However, allowable (currently) on tidal waters is for sewage to be discharged at sea (or on a falling tide here at Conyer) so I installed a manually operated diverter valve, sewage pump and sea-cock. This system gives us the capability of either discharging the tank to sea, or by emptying it at a conventional pump-out station. The toilet is new, but I utilised the existing 240v macerator unit.
