Improved indicators of water use performance and productivity for sustainable water conservation and saving
TL;DR: Water use concepts and performance descriptors that may be useful in defining conservation and saving of water are discussed with the aim of improving the overall performance and productivity of water use New indicators are proposed which include water reuse and aim to assist in identifying and providing clear distinctions between beneficial and non-beneficial water uses as mentioned in this paper.
