Singapore and Malaysia signed a renewed water agreement on November 4, 2023, updating the terms of the 1962 Johor River Water Agreement that supplies up to 250 million gallons of raw water per day to Singapore. The new pact, announced jointly by Singapore’s Ministry of Sustainability and the Environment and Malaysia’s Ministry of Energy and Natural Resources, adjusts pricing and operational conditions while maintaining the original 99-year lease structure that expires in 2061.
Renewed terms and pricing adjustments
The revised agreement increases the price Singapore pays for raw water from Johor. Under the 1962 terms, Singapore paid 3 sen per 1,000 gallons. The new rate has not been publicly disclosed in full, but officials confirmed it reflects current operational and infrastructure costs. Malaysia’s Minister of Energy and Natural Resources, Nik Nazmi Nik Ahmad, stated that the updated pricing “ensures a fairer arrangement that better reflects the value of water resources and the costs of maintaining the supply system.” Singapore’s Minister for Sustainability and the Environment, Grace Fu, said the revised terms “recognize the long-standing partnership between our two countries and the need for sustainable water management.”
The agreement also includes provisions for joint investment in water treatment facilities and pipeline upgrades. Both governments will share costs for a new water treatment plant in Johor, expected to be operational by 2028. The plant will increase raw water capacity by 20 percent, supporting growing demand in both Johor and Singapore.
Historical context of the water pact
The 1962 Johor River Water Agreement was signed between the Federation of Malaya and the state of Singapore, two years before Singapore’s independence. It grants Singapore the right to extract up to 250 million gallons of raw water daily from the Johor River. In return, Singapore supplies treated water back to Johor at a rate of 50 sen per 1,000 gallons. The agreement runs for 99 years, expiring in 2061.
Water has been a sensitive issue in bilateral relations. Malaysia has periodically sought to renegotiate terms, arguing the original price was too low. In 2018, then-Malaysian Prime Minister Mahathir Mohamad called the 3 sen rate “ridiculous” and threatened to raise the price. Singapore has consistently maintained that the 1962 agreement is a binding international treaty. The November 2023 renewal avoids a protracted dispute by introducing mutual concessions.
Operational and environmental commitments
Beyond pricing, the renewed pact includes environmental safeguards. Both countries agreed to monitor water quality in the Johor River catchment area. Singapore will provide technical assistance for pollution control and watershed management in Johor. The Malaysian government will enforce stricter regulations on industrial discharge and agricultural runoff upstream.
Grace Fu said the environmental provisions “protect the long-term viability of the water source for both communities.” Nik Nazmi added that “sustainable management of the Johor River basin is a shared responsibility that benefits Malaysians and Singaporeans alike.” The agreement also establishes a joint committee to review water quality data and address emerging issues.
Implications for bilateral relations
The renewal signals a pragmatic approach to a historically contentious issue. Water has been a flashpoint in Singapore-Malaysia relations for decades, with disputes over pricing, supply, and sovereignty. The 2023 agreement was negotiated over 18 months, involving multiple rounds of talks between senior officials from both countries.
Reports note that the deal reflects broader cooperation on resource management. Singapore relies on imported water for about 30 percent of its supply, with the rest coming from local catchment, desalination, and NEWater recycling. Johor, in turn, depends on treated water from Singapore for its southern districts. The agreement ensures continuity of supply for both sides.
The renewed water pact comes amid other bilateral cooperation efforts, including the Johor Bahru-Singapore Rapid Transit System link, set to open in 2026, and joint economic zones in Iskandar Malaysia. Both governments have framed the water agreement as part of a broader partnership.
The November 4 signing ceremony took place in Putrajaya, with both ministers present. The agreement is effective immediately, with the new pricing and operational terms phased in over two years. Future reviews are scheduled every five years to adjust for inflation and changing conditions.
The renewed pact does not alter the 2061 expiration date. Both governments have indicated they will begin discussions on a post-2061 arrangement within the next decade. For now, the agreement provides stability for one of the world’s most water-stressed regions, ensuring that Singapore and Johor can continue to share a critical resource on terms both sides consider fair.
