Domestic water use in Singapore from 1995 to 2009 (liters per person per day) showing improving efficiency of use.
“Today, Singapore depends on four different sources of water: about 35% of their water comes from rainfall captured on its own limited territory, about 15% is high-quality recycled water produced by its NEWater treatment plants, 10% comes from desalinated water, and around 40% is water imported from Malaysia.
“As a result of the heavy dependence on Malaysia, the Public Utilities Board (PUB) of Singapore has been working for years to do two key things: reduce the demand for water by improving efficiency and cutting waste; and expanding alternative sources of supply. California could take a lesson from these two approaches. I know that water agencies (state, federal, local, and agricultural) argue the state is already doing these things, but compared to Singapore, California’s efforts are half-hearted.”
