Malaysia has built a dam along the Johor River, near Kota Tinggi, to prevent seawater from entering upstream and affecting the catchment of water from the Johor River. Members may not see how shallow the Johor River is and the seawater comes from the strait to Kota Tinggi. That lock helped. The ministry`s comments are a response to Johor Menteri Besar Osman Sapian`s statement that the state plans to source treated water instead of Singapore. We have already reported this to Malaysia in 2002, when Singapore last negotiated on water as part of a package agreement with Malaysia. Measures must now be taken and taken to protect the Johor River from pollution and increase river performance and manage the total amount of water taken from the river. Singapore and Malaysia could otherwise find themselves in a very difficult situation on the road, especially in dry weather, and if you think that climate change will make the situation worse. This agreement, the 1990 water agreement, led to the construction of the Linggiu Reservoir, completed in 1993, to ensure the sustainable withdrawal of 250 million gallons of raw water per day from our claims in the Johor River. On June 25, 2018, Malaysian Prime Minister Mahathir Mohamed announced his intention to renegotiate the agreement with Singapore, as the low price at which water is exported to Singapore has caused Malaysia to lose considerable revenue.
 PUB and its counterpart in Johor, Badan Kawalselia Air Johor (BAKAJ), have a close relationship. PUB and BAKAJ meet regularly and conduct useful discussions on current weather trends, water levels at various dams and dams in Johor and plans for the development of water resources. PUB and BAKAJ are also working closely together on the Johor River Dam project. The Johor River Dam, in operation since August 2016, helps prevent the use of saline and improves the reliability of the Johor River water supply, benefiting Singapore and Johor. At the end of the day, water is only one issue in many bilateral areas of cooperation and we must not allow a single subject to tint the overall positive and complex relations. We should move forward to see how we can work together and resolve issues for mutual benefit and for the benefit of future generations. Malaysia cannot unilaterally revise the price of water. Our legal situation remains unchanged.
Osman`s statements came a day after Prime Minister Mahathir Mohamad called on Johoreans to speak out on the “morally wrong” water deal between Malaysia and Singapore. If Malaysia had exercised the right to check the price of water in 1987, as stipulated in the 1962 water agreement, Singapore could have made various investment decisions to develop the Johor River, including the Linggiu Dam. The first water agreement was signed between Sultan Ibrahim II of Johor and the city of Singapore`s municipal commissioners on December 5, 1927, under the Legislative Council of the Straits Settlements.
