From 2000 to 2015, $7 billion was invested in water infrastructure. In the next five years Reservoir (2017 - 2021), PUB will invest a further $4 billion in water infrastructure. Our future water supply will come largely from costlier water sources, namely NEWater and desalinated water. These are weather-independent sources that will strengthen the resilience of our water supply against the effects of dry weather caused by 4taps climate change..
