Singapore can draw up to 250 million gallons of water a day from the Johor River (1962 Water Agreement), and Singapore is thus required to provide Johor with treated water (up to 2% of the imported water). The 1962 Water Agreement will also expire in 2061. Constructed by PUB supplementary to the 1962 Water Agreement, a 1990 agreement with Johor was written. The Linggiu Reservoir which is located upstream of the Johor River Waterworks, releases water into the Johor River to supplement its flow. This allows for efficient abstraction of raw water at the Johor River Waterworks, owned and operated by PUB for treatment.
Playing our part in preserving the eco-system and enabling water quality in the reservoirs
Population and water consumption estimates are the basis for determining the flow demand of a water supply and distribution system especially in such a small country like Singapore. As demand for water continues to increase in tandem with population and economic growth, we will need to plan and implement water infrastructure well ahead to secure an adequate and affordable supply of water for the future generations.
