Singapore Johor Water Agreement


Yes, yes. As part of the 1962 water agreement, we continue to purchase 250 million gallons of raw water per day from the Johor River. In return, we are obliged to supply Malaysian with daily water treated with up to 2% (or 5 mgd) of the water delivered to Singapore. In practice, OVER the years, at Johor`s request, PUB has provided additional drinking water every day, in addition to the 2% we must provide under the 1962 water agreement. The PUB has also responded to Johor`s ad hoc demands for even more drinking water in times of severe and prolonged drought in Johor and when the Johor water station experiences pollution events or is routinely maintained. Additional drinking water is provided to Johor on the basis of goodwill and without prejudice to our rights under the 1962 water agreement. At the press conference, Mr. Lee also noted that Johor had built hydroelectric power plants on the Johor River, in front of the PUB water station in Kota Tinggi. We have already reported this to Malaysia in 2002, when Singapore last negotiated on water as part of a package agreement with Malaysia. “For example, the ministry has issued close to RM 100 million to build the dam on the Johor River to prevent salt water from seeping into the river. It is clear that the huge investment does not correspond to the price of raw water of 3 sen per thousand gallons,” he said in the statement. Singapore pays 3 sen per thousand gallons of raw water and sells treated water to Johor with 50 sen per thousand gallons, a fraction of the cost of water treatment.

Our water needs are increasing. By 2060, our water consumption, which is now 430 mgd, is expected to almost double. So we need to plan ahead to find the water and invest in weather-resistant water sources. Today, we have three desalination plants. By 2020, we will have two more facilities in Marina East and Jurong Island. This year, we began work on Phase 2 of the Deep Tunnel Sewerage System (DTSS), which will improve our used water management and boost NEWater production once completed in 2025. Malaysia had previously acknowledged that it had decided not to review the agreement in 1987 because it had benefited from the price regime. Malaysia cannot unilaterally revise the price of water.

Our legal situation remains unchanged. The two sides must also discuss the performance and water quality of the Johor River to ensure that Singapore can continue to promote our 250 million gallons of raw water per day under the 1962 water agreement for the remaining 41 years of the water agreement. Growth in our local watersheds is limited, with two-thirds of our island already a watershed. This means that any additional water supply must be provided by NEWater or desalted water. While NEWater and desalies are weather resistant, they are more expensive to produce. Water must be taken into account to reflect the long-term marginal cost (LRMC) of producing and promoting our next drop of water, probably from NEWater and desalies. On August 31, 2011, the 2011 water contract expired and the hydropower plants and facilities were handed over to the Johor State Government. The shed included the skudai and Gunung Pulai water treatment facilities, built by the Public Utilities Board and managed by them for 50 years, as well as two pump houses in Pontian and Tebrau.

The benefits can certainly be used to help Malaysia develop a sustainable water supply in Johor,” he said.

In 1927, in order to ensure an adequate supply of water in the rapidly modernizing colonial city of Singapore in the 1920s, the singapore tour and Sultan Ibrahim of the state and territories of Johor, in the nearby city of Malaya, signed an agreement allowing Singapore to lease land in Johor and use its water for free.
