Johor First State To Adopt Tier 4 Data Centre Technology - Onn Hafiz

JOHOR BAHRU, 11 Aug (Bernama) -- Johor has become the first state in Malaysia to adopt Tier 4 data centre technology, integrating advanced air cooling and wastewater recycling systems as part of its commitment to sustainable development in the sector.

As of June 30, 2025, Johor Special Water (JSW) has received requests for alternative water supply totalling 136 million litres per day from data centres in the state, underscoring rapid industry growth and increasing demand for sustainable water solutions.

Johor Menteri Besar Datuk Onn Hafiz Ghazi said several important agreements were signed today to support Johor’s water sustainability initiatives and green technology advancement.

“First, the Treated Effluent Supply Agreement between Indah Water Konsortium (IWK) and JSW marks a strategic collaboration to supply treated effluent from IWK sewage treatment plants across Johor for the production of reclaimed water to be used in data centre cooling systems.

“This makes Johor the first state in Malaysia to adopt Tier 4 data centre technology, which includes air cooling systems and wastewater recycling technology,” he said in his opening speech at a ceremony to recognise the use of alternative water in Johor's data centre industry here today.

Onn Hafiz said that the second agreement, between JSW, Bridge Data Centres (BDC) and Computility Technology (Malaysia) Sdn Bhd, involves supplying treated effluent for reclaimed water production.

“Since June 9, 2025, BDC has begun producing reclaimed water at its data centre located in the Ulu Tiram Industrial Area -- making it the first investor to directly apply this technology from an IWK treatment plant.

For Computility, the development of its reclaimed water production system is progressing intensively and is now in the final phase of implementation.

Located at Setia Eco Garden, Iskandar Puteri, the project is expected to be fully completed and operational by December, further strengthening Johor’s sustainable data centre ecosystem,” he explained.

He also highlighted that the third agreement, a Raw Water Supply Agreement between JSW and DayOne Data Centres Sdn Bhd, under which JSW will supply raw water from Sungai Tebrau for treatment and use in the cooling system of a data centre in the Kempas Tech Park.

“Construction works for the reclaimed water supply system are actively ongoing and are expected to be completed and operational by November,” Onn Hafiz said.

The Johor government hopes these agreements will further strengthen water sustainability efforts while accelerating the development of resilient, energy-efficient, and environmentally friendly data centre infrastructure in the state.
