Water boatman is a unit on the water, that takes in polluted or sea water, distills it & either stores the pure water – or pumps it ashore.

The power is drawn from a vertical axis water turbine, driving a water brake which provides the heat for the low temperature heavily insulated still.

The excess salt or pollution flows on through.

The unit makes 1,000 litres a day.

All materials are plastic and so impervious to corrosion by the warm brine. The design life – with occasional cleaning is 20 years.
