Uncovering Amazon’s Impact on the Colorado River: A Closer Look at Water Usage

Amazon has committed to investing $20 million in water conservation projects along the Colorado River, which serves as a crucial water source for 40 million people in the Western US.

Amid growing concerns about water usage by tech companies, Amazon aims to become water positive by replenishing more water than it uses by the end of the decade. While the company has disclosed some information about its water consumption, there is still a need for a comprehensive understanding of its overall impact.

Amazon has launched the Colorado River Basin Collaborative, with a goal to establish one of the largest corporate water conservation initiatives for a single US watershed. The company plans to raise $100 million over two years, including its own $20 million contribution, for water conservation efforts.

Amazon, with a significant presence in California due to its warehouses, has pledged $2.2 million to detect and repair leaks in Orange County. This initiative is expected to save 189 million gallons of water annually.

As part of the collaborative effort, companies can engage in independent contracts with selected conservation projects vetted by the United Nations-backed Water Resilience Coalition. Amazon has also joined this coalition, which includes other major brands like Microsoft and Meta.

Tech companies are facing backlash over the water usage of their data centers, particularly with the increasing demand for AI technologies. The Colorado River water cuts are projected to impact utility rates in Arizona, raising concerns about the potential exacerbation by data centers.

In 2025, Amazon reported that its data centers globally consumed 2.5 billion gallons of water, showing a 2% reduction in consumption compared to the previous year. The company attributes this improvement to a 52% increase in water efficiency since 2021.

While Amazon discloses water use per unit of power for its data centers, experts emphasize the importance of considering overall water consumption and peak demand requirements. Sustainability reports from Microsoft and Google provide detailed insights into total water usage across their operations.

A 2025 investigation by The Guardian raised concerns about Amazon’s water usage calculations, highlighting the exclusion of water consumption related to electricity generation. Executives defended their approach, emphasizing progress towards sustainability goals.

Despite challenges, Amazon remains committed to its sustainability goals, including the recent Colorado River initiative. The company’s sustainability officer, Kara Hurst, emphasizes the interconnectedness of water and climate issues.

While Amazon aims to become water positive, its carbon footprint increased by 16% in 2025, reflecting broader trends in the tech industry’s pursuit of AI advancements.
