The first Amphiro study in Asia starts in Singapore within the cooperation of the ETH Zurich, University of Bonn, and the National University of Singapore.
As of today, already one fifth of the world’s population experiences absolute water scarcity; by 2030, almost half the world’s population is expected to live in regions of high water stress (United Nations, 2013). For countries without sufficient fresh water resources, effective water demand management strategies are particularly crucial to reduce their dependence on their neighbor states. In this context, the Public Utilities Board of Singapore has set up a National water conservation plan with the goal of reducing the current per-capita demand for water from 151 to 147 liters by 2020 and 140 liters by 2030. A total of 920 smart shower meters are deployed for 4-6 months all over Singapore. In a randomized controlled trial, we will investigate the effectiveness of different goal levels for water conservation with and without real time feedback on goal attainment.
