WATER POSITIVITY
Scaling wastewater reuse strategy The Hong Kong project functions as a pilot within AWS’ wider plan to expand the use of recycled water across its global data centre portfolio. The company has stated its intention to increase the number of facilities using recycled water by four times by 2030.
This scaling effort depends on regulatory alignment, infrastructure availability and economic feasibility. Not all regions have access to reclamation facilities capable of supplying treated water at required volumes. In such cases, operators may need to invest in dedicated treatment systems or pursue alternative strategies.
Bryan Ha, Head of Public Policy, Hong Kong, AWS Greater China Region, positions the project within a longer-term framework. He says“ I am grateful for the opportunity to work with my multidisciplinary colleagues at Amazon and former colleagues in the HKSARG to incubate this pilot project over the past year, which could potentially be scaled up across the territory and bring long-term impact on preserving our precious freshwater resources. This is a classic example of creating synergy to advance our common agenda.”
As data centre demand grows in Asia Pacific, operators face increasing scrutiny over resource use. Wastewater reuse offers a pathway to reduce freshwater dependency while maintaining service delivery. The AWS Hong Kong case study shows how this approach can be implemented through coordination between operators and public authorities, supported by treatment technology and upstream investment.
