The WaterCube 2 can mainly be used in coastal areas and on islands where normal sources of fresh water are limited and/or of bad quality.  The unit is not only suited for private homeowners, but can also be used in hospitals and health clinics and for remote communities.  It is also ideal for commercial use such as in small hotels, restaurants, camper parks, marinas, yacht clubs, island settlements and resorts, etc. The water purifier may also be used as a primary source or as a back-up water purifier for the provision of drinking water to police and military facilities, or to public institutions in coastal areas or on islands.....And if you need more water than 4,800 litres per day (1270 gallons) you can install more units in parallel or choose our Watermaker series (WM 7000E or WM 9000E).
