The Germans have a system called Citywasser. This is a pipe fitted through the caravan floor and connected to a float system (like a domestic toilet) fitted to the onboard tank. Below the floor there is a snap on connector (Hoselock type) for the hose to couple up to the pipe. It is not difficult to make your own set up using domestic fittings from a DIY store at a considerable saving in costs.
