Johor seeks assessment of DayOne water plant surplus for public supply
Sungai Tebrau’s flow is about 80 million litres per day, compared with DayOne’s maximum consumption of around 10 MLD, the Menteri Besar said.

Johor wants an urgent technical assessment of whether residents could receive surplus treated water from DayOne’s treatment plant. Menteri Besar Datuk Onn Hafiz Ghazi asked the company, Perbadanan Darul Ta'zim (PDT) and Ranhill SAJ to examine the proposal together.
At a Nov 5 ceremony launching the alternative water source at DayOne Kempas Tech Park, Onn Hafiz described the proposal as feasible. He cited a flow of about 80 million litres per day (MLD) in Sungai Tebrau, compared with the company’s maximum consumption of around 10 MLD.
The Singapore-based operator draws raw water from the polluted river and treats it for its data centre, he said. This arrangement reduces demand on the existing treated-water network. The proposed discussions would examine whether the technology could also help meet residents’ water needs as Johor’s economy expands.
On electricity, Onn Hafiz said DayOne was working with Tenaga Nasional Bhd on renewable energy, solar panels and other measures to provide sufficient power for its artificial intelligence operations.
He also said DayOne had set aside RM3 million to support education and talent development in Johor, with a commitment to contribute that amount annually. A technical committee would continue scrutinising investments involving data centres and AI to protect public and state interests, he added.
