When Singapore imposed restrictions on new data center construction to protect its own limited water and energy resources, the environmental costs did not disappear - they relocated. According to an analysis published in The Diplomat, the Malaysian state of Johor has absorbed much of the resulting infrastructure growth, raising concerns about whether local communities there retain meaningful access to water resources.
The cross-border shift
Singapore, a city-state with significant constraints on land and fresh water, moved to limit data center expansion within its own borders. The policy was designed to preserve national resources and reduce strain on local utilities. However, the demand for digital infrastructure in the region did not diminish. Instead, international technology companies shifted planned developments to Johor, which borders Singapore to the north and offers cheaper land, proximity to Singapore's fiber networks, and access to water sources.
Data centers are among the most water-intensive facilities in the modern built environment. They consume large volumes of water for cooling systems that prevent servers from overheating. A single large-scale facility can use millions of liters of water per day, drawing on local supplies that communities, farms, and ecosystems also depend on.
Questions of equity and governance
The Diplomat report frames the situation as a question of environmental justice and the human right to water. Critics argue that by exporting the problem to a neighboring jurisdiction with different regulatory standards and less political leverage over multinational corporations, Singapore has effectively transferred an environmental burden onto communities that had no voice in the original decision.
Johor's rapid transformation into a regional data center hub has attracted significant foreign investment and created employment, but local residents and advocacy groups have raised questions about whether water allocation priorities adequately account for agricultural needs and household consumption in surrounding areas.
A regional governance gap
The situation highlights a broader challenge in regulating transboundary environmental impacts. Water rights and land-use decisions in Johor fall under Malaysian jurisdiction, while the demand driving development originates largely from Singaporean policy and global technology firms headquartered in the United States, Europe, and East Asia.
Analysts quoted in the report suggest that without coordinated regional frameworks addressing water use in the digital economy, similar dynamics are likely to repeat across Southeast Asia, where data infrastructure investment is expanding rapidly and regulatory capacity varies significantly between jurisdictions.
Neither Singaporean nor Malaysian government officials were directly quoted in the source material, and the precise volume of water currently consumed by data centers in Johor was not specified in the summary available. The full analysis appears in The Diplomat's April 2026 edition.
