I bought SolarRO watermaker for my houseboat on the river. The river water is dirty brown and people are amazed that I get completely clean drinking water from it. The equipment produces 150 litres per hour from the River Aura and 50 litres per hour from the Baltic Sea. The system is really easy to use and I get water from the kitchen tap for drinking and from a tank for showering. Next year I intend to commission a remote-control system, that can automatically adjust the tank fill rate. The equipment is situated under the bed, and by remote control I can also set it to start up only during the day.
