01 What Happened

Greenland International Industrial Center said its recycled-water treatment plant in West Java has operated with a capacity of 8,000 m³/d since the reclamation program began in 2025. The facility enables reuse of approximately 60% of treated effluent from the estate WWTP. AWS is the first tenant reported to use the reclaimed water for data-center cooling. GIIC states that the reclaimed water complies with cited Indonesian regulations for industrial utility applications.

02 Key Takeaways

  • 01 Plant capacity is 8,000 m³/d; this is not a disclosed AWS demand figure.
  • 02 Approximately 60% of the estate WWTP’s treated effluent can be reused through the facility.
  • 03 Cooling-water acceptance should be based on scaling, corrosion, biofouling, blowdown and backup-supply criteria.

03 Why It Matters

An 8,000 m³/d reclaimed-water plant is a meaningful industrial utility asset, but capacity alone does not establish suitability for cooling towers.

The treatment objective must be tied to the cooling-water mass balance and target cycles of concentration. Conductivity, calcium hardness, alkalinity, silica, chloride, sulfate, ammonia, orthophosphate, TOC/COD, turbidity, suspended solids and microbiological activity determine scaling, corrosion, deposition and biological growth. Depending on the feed and operating target, the treatment train may require tertiary filtration or UF, softening, RO, activated carbon or biological polishing, and controlled disinfection.

04 ATLAS Engineering View

For a data-center user, the commercial question is not only water price per cubic metre. It is assured availability under peak thermal load, storage and dual-feed arrangements, compatibility with cooling equipment and chemical programs, blowdown disposal capacity, and the consequences of an off-spec event. The reported 8,000 m³/d is the plant’s treatment capacity; it should not be interpreted as AWS consumption. A bankable reuse contract needs metering boundaries, quality limits, response times, curtailment rules and a verified potable-water or alternative backup strategy.
