Mosacat turned a water complaint into a Google data-center suspension

Mosacat, a Santiago organization opposing resource exploitation, discovered that official documents authorized Google's second data center to extract more than 7 billion liters of water annually. The scale was especially consequential in one of Chile's most water-stressed regions.

Rather than leave the issue inside the permitting record, Tania Rodríguez and the group held demonstrations after uncovering the planned diversion. The decision converted a technical water-use finding into a visible community campaign against the project's environmental impact.

In 2024, Santiago's environmental tribunal suspended construction until Google reassessed its environmental impact. The campaign also brought Mosacat international attention and connected it with activists challenging data centers elsewhere.

Santiago's environmental tribunal suspended construction until Google reassessed its environmental impact, while Mosacat gained international attention.

The water risk was hidden in public documents, so document review supplied a concrete fact around which residents could organize.

Demonstrations made a specialized permitting issue visible to the public and decision-makers.

A formal tribunal process turned community pressure into a binding pause and required reassessment.

The campaign framed the dispute around water and accountability rather than opposition to technology in general.

When a project's hidden externality is buried in technical filings, quantify the local risk, mobilize affected residents, and force a formal review.

The suspension was a pause, not a permanent veto. Mosacat continued monitoring AI companies, sought no more data centers in Santiago and environmental compensation, and connected with activists worldwide. The group later ended its dialogue with the government after concluding that the National Data Center Plan was being built for technology companies.
