At the Institut Teknologi Sepuluh Nopember (ITS), the efficiency of water usage was carried out in two ways, that is an efficiency that using dual flush in toilets, as well as using sprinkled water to support smart eco campus program. Dual flush is a toilet watering technology using two flush sizes. Flush with a large size will remove about 6-9 liters of water, while a small flush will remove about 3-4 liters of water.
The second one is water sprinkle technology, a form of efficient use by applying a system that uses the water as little as possible but still can be distributed to the large areas by using the pressure in the pipe. This technology has been applied on watering plants and fields in the ITS area, especially around the Manarul Ilmi ITS Mosque.
