Starting work on the plumbing.
Two jerry cans with food safe linings from Wavian,
http://www.wavianassociates.com, carry a total of 9 gallons of water (that hopefully wont turn brown if left for a while). Cans are exactly the same size as a diesel jerry can, allowing me to swap one of the water cans for fuel if I need to.

Cans are held in place by a timber section attached to the back door which stops them moving when the door is closed. 12mm ID plastic hosing takes water out of the can to a foot pump I found in an old camper van at the scrappy. Pump positioned so that I can lift the lid on the sink and pump from outside the van.

Pump (marked Galley Gusher MK3) is self priming which is very helpful when swapping cans. 90 degree hose fittings prevent kinking of the hose as it makes a sharp turn. Plan is to drain the sink in to the plastic petrol can next to the pump with a shelf on top of the pump and waste can.
No idea what to use as a faucet yet. The sink and the MDF lid are flush when closed so I think I might have to route in to the lid somewhat to get a pipe to fit through. Very open to any suggestions
