Support for the Data Centre Industry
These projects prove that Johor is not only ready to meet domestic and industrial needs, but is also able to accommodate the rapid development of new sectors including the data centre industry.
“Johor is the only state in Malaysia to have a two-tier data centre approval committee to ensure a balance between economic development and resource sustainability:
Technical Committee – chaired by Ir. Ts. Mohd Fazli bin Mohamad Salleh.
Main Committee – chaired by Datuk Mohd Jafni bin Md Shukor.
This approach ensures that each data centre approval is scrutinised technically and strategically, without affecting the people’s water supply.
System Improvement & NRW
The State Government together with Ranhill SAJ (RSAJ) continues to strengthen water management. Last May, experts from Wessex Water, UK conducted a technical assessment to improve system efficiency. Among the main achievements:
*NRW (Non-Revenue Water) was successfully reduced to 24.1% as of July 2025 –the lowest in Malaysia.
* Proposed improvements include increasing water storage capacity, upgrading old assets, automating plants through SCADA, and introducing a Water Charter to ensure the sustainability of water supply.
State Government Commitment
“The Johor State Government is committed to ensuring that water supply remains stable, sufficient, and sustainable for all levels of the people and industry.”
“Through the implementation of new water resource projects, modern technology, and sustainability initiatives, Johor will continue to be a model state in water management and emerge as a major hub for the development of regional data centers without compromising the people’s right to enjoy a quality water supply,” the statement concludes.
