• GIIC’s reclaimed water plant can treat 8,000 cubic metres daily and reuse about 60% of the estate’s treated wastewater.
• AWS is the first GIIC tenant to use reclaimed water for data center cooling, reducing demand for potable freshwater.
• The program supports Indonesian water regulations while offering a model for more resilient industrial and digital infrastructure.

Greenland International Industrial Center has expanded its water reclamation program, with Amazon Web Services becoming the first tenant to use reclaimed water for data center cooling.

The initiative aims to reduce freshwater consumption across the industrial estate in Kota Deltamas. It also addresses growing concerns about water availability as industrial activity and digital infrastructure expand across Indonesia.

The United Nations estimates that global water demand could exceed available clean water supplies by up to 40% by 2030 if current consumption trends continue. Industry accounts for about 19% of global freshwater withdrawals, placing water efficiency higher on corporate and government agendas.

Reclaimed Water Supports Industrial Growth

GIIC began developing its water reclamation program in 2025. The industrial estate is managed by PT Puradelta Lestari Tbk, a subsidiary of Sinar Mas Land and Japan’s Sojitz Corporation.

AWS collaborated with GIIC to implement the project and became the first tenant to draw reclaimed water from the facility. The water will support cooling operations at its data center.

Hongky J. Nantung, President Director of PT Puradelta Lestari Tbk, said: “Sustainability is at the core of GIIC’s development strategy. Since the launch of our water reclamation program in January 2025, we are pleased to see tenants embracing this initiative. Amazon Web Services is the first tenant to adopt reclaimed water from our facility for its data center cooling operations. This demonstrates how sustainable infrastructure can reduce freshwater consumption while supporting the long-term growth of industries at GIIC.”

The GIIC Recycled Water Treatment Plant has a treatment capacity of 8,000 cubic metres per day. It allows the estate to reuse about 60% of the treated effluent produced by its wastewater treatment plant.

The reclaimed supply can be used for industrial utility applications, reducing reliance on clean water sources. It also provides tenants with a more resilient water supply during periods of rising demand or local scarcity.

Regulation Shapes Water Reuse

GIIC said the reclaimed water complies with Indonesian regulatory requirements. These include Ministry of Health Regulation No. 02 of 2023 and Government Regulation No. 66 of 2014.

Regulatory compliance will be central to expanding reclaimed water across industrial parks. Operators must demonstrate that treated water meets safety and quality standards for its intended use.

For governments, such systems can reduce pressure on municipal water supplies without restricting industrial development. For companies, they can lower water-related operational risks and support environmental reporting commitments.

AWS has set a global goal to return more water to communities than it uses in its operations by 2030. The company said it is 75% of the way toward that target.

Saji PK, Director for Data Center Operations, AWS APJC, added, “At Amazon, we are committed to contributing to solutions that address the growing challenge of water availability in the communities where we operate. This is why we have taken a global goal to return more water than we use in our operations back to communities by 2030, and are 75% of the way there. Other than reducing the water we use and replenishing water back to communities, using recycled water where possible is a key strategy for our data centre operations because we believe potable water should be reserved for people and communities who need it most. It also supports local water security, promotes circular water management practices, and demonstrate a scalable model for sustainable industrial development that other organizations can follow. We are proud to be part of GIIC’s water reclamation initiative, which demonstrates how collaboration between infrastructure developers and technology companies can create meaningful environmental and social outcomes.”

Data Centers Face Rising Water Scrutiny

Water use is becoming a material ESG issue for data center operators. Cooling systems can place pressure on local supplies, especially in regions experiencing rapid urban and industrial growth.

Using reclaimed water gives operators an alternative to potable supplies. It can also improve relationships with communities concerned about competition for essential resources.

Investors are likely to pay closer attention to whether new data centers have credible water strategies. Site selection, cooling technology, water availability and regulatory exposure are becoming linked investment considerations.

GIIC spans about 2,200 hectares in Cikarang. Its infrastructure includes wastewater treatment, centralized clean water production, solar power, access to green electricity and extensive open space.

The estate also has direct access to the Jakarta-Cikampek Toll Road and two dedicated toll interchanges. That connectivity supports industrial expansion, but it also increases the need for utilities that can grow without placing excessive strain on local resources.

GIIC’s program offers a practical example of how industrial estates can connect tenant growth with circular water systems. Its wider significance will depend on whether more tenants adopt reclaimed water and whether similar projects can be replicated across Indonesia’s industrial corridors.
