Electro arts offers auto flush for washrooms. Electronic switches are available with an auto-flush system, which saves water in the urinals and maintains the cleanliness. The unit is battery-operated and performs infrared technique. Any person standing in front of the unit for more than 8 seconds is detected and the valve operates to allow water to flow for preset time. Water is permitted to flush only after the person moves away. Thus flushing of water becomes totally automatic and it saves thousands of litres of water.
