Singapore’s Public Utilities Board supplied additional treated water to Malaysia at Johor’s request after pollution at Johor’s water plants led to a disruption.
According to recent reports in Malaysian daily The Star, a sand-mining company caused river pollution which disrupted water treatment at the Semangar plant in Johor on Jan 1.
The disruption affected 3,000 houses in Taman Desa Tebrau and surrounding areas.
An additional 6 million gallons per day (mgd) of treated water was supplied between Jan 2 and 4 according to PUB’s response to the Straits Times.
“At Johor’s request, PUB helped to tide Johor residents over the water supply disruption by turning on PUB’s Pasir Gudang offtake and supplying an additional 6 million of gallons per day (mgd) of treated water between 2 and 4 January 2019.
“This was on top of the 16 mgd that we usually supply Johor,” it added.
Singapore is required to supply Johor with 5 mgd of treated water, said PUB, citing the 1962 Water Agreement.
“In practice, we have been supplying 16 mgd of treated water to Johor at their request. On top of this, between 2 and 4 January 2019, we have supplied a further 6 mgd of treated water (above the 16 mgd of treated water) to Johor when it needed more water because its water plants experienced pollution.
“Last year, we similarly supplied additional water in excess of the usual 16 mgd for 20 days at the request of Johor,” said the agency.
“This has been done without prejudice to our rights under the 1962 Water Agreement,” said PUB, noting the “long-standing cooperation between the water agencies of the two countries”.
“PUB has thus far been responsive in assisting Johor residents to reduce the impact of their water disruptions, in the spirit of good neighbourliness,” it added.
