Imported Water

The 2nd National Tap

Under the 1962 Water Agreement, Singapore can draw up to 250 million gallons of water a day from the Johor River, and Singapore is obliged to provide Johor with treated water up to 2% of the water we import. The 1962 Water Agreement will expire in 2061. Constructed by PUB under a 1990 agreement with Johor supplementary to the 1962 Water Agreement, the Linggiu Reservoir is located upstream of the Johor River Waterworks and releases water into the Johor River to supplement its flow. This enables reliable abstraction of raw water at the Johor River Waterworks which is owned and operated by PUB for treatment.​
