Water Usage

Summary

Hyperscale data centers are among the most water-intensive industrial facilities in operation. Project Tango's proposed 3.69 million square foot facility is estimated to consume approximately 1.7 million gallons of water per month — primarily for evaporative cooling systems that prevent server overheating. In a region already managing water scarcity, population growth, and environmental pressures, this consumption poses a direct threat to Palm Beach County's water supply.

How Data Centers Use Water

Modern data centers generate enormous amounts of heat. Thousands of high-performance processors running AI workloads produce thermal energy that must be continuously dissipated. The most common cooling method is evaporative cooling, which works by passing water through cooling towers where it evaporates, absorbing heat in the process.

For every megawatt of IT power, a typical data center consumes between 1.8 and 7.0 million gallons of water annually, depending on climate and efficiency. South Florida's hot, humid climate means higher cooling demands for more months of the year, pushing consumption toward the upper end of this range.

Palm Beach County's Water Challenges

Palm Beach County relies primarily on the Surficial Aquifer System and the Biscayne Aquifer for its freshwater supply. These sources are already under stress from:

Population growth: Palm Beach County's population has grown by over 10% in the past decade, increasing residential demand.
Agricultural competition: The region's significant agricultural sector, including sugar cane and vegetable farming, draws heavily from the same aquifers.
Saltwater intrusion: Rising sea levels and over-pumping are causing saltwater to migrate inland into freshwater aquifers, reducing available supply.
Drought cycles: Florida experiences periodic droughts that stress water reserves, particularly during the dry season (November through May).

The South Florida Water Management District has implemented water restrictions during drought periods. Adding an industrial consumer using 1.7 million gallons monthly creates a permanent, inflexible demand that does not adjust during water emergencies.

The Scale of Consumption

To put 1.7 million gallons per month in perspective:

The average Florida household uses approximately 9,000 gallons per month
1.7 million gallons could supply roughly 189 homes every month
Over a year, that is 20.4 million gallons — enough to fill more than 30 Olympic swimming pools
This consumption is continuous, 24/7, 365 days per year — it does not decrease during droughts

As AI workloads intensify and the facility scales to full capacity, water consumption is likely to increase beyond initial estimates. Google reported that its global data center water consumption increased 20% in a single year (2022-2023) due to AI demand growth.

Environmental Impact on Local Waterways

The water discharged from cooling towers contains elevated concentrations of dissolved minerals, treatment chemicals, and thermal energy. This "blowdown" water must be disposed of, typically through wastewater systems or direct discharge. In either case, it can affect local water quality and aquatic ecosystems.

The proposed site is adjacent to canal systems connected to the broader Everglades watershed. Any disruption to local hydrology — through excessive withdrawals or discharge of warm, chemically treated water — could impact this sensitive ecosystem.

No Meaningful Public Review

The original 2016 zoning approval for "data warehouse" use did not contemplate the water demands of a hyperscale data processing facility. The community had no opportunity to evaluate or comment on water consumption projections because the true nature of the facility was not disclosed until 2025.
