How alternative sources, reuse, and flexible infrastructure can help communities protect freshwater resources
The rapid expansion of AI, cloud computing, and digital services is fueling demand for data centers across the United States. While these facilities offer jobs and attract economic investment, they also increase demand for reliable water infrastructure. Communities must balance economic growth with responsible water management by planning for diverse water supplies, resilient infrastructure, and long-term capacity before demand outpaces existing systems.

Why Data Centers Need So Much Water
Data centers house thousands of high-powered servers that generate significant heat. Keeping that equipment within safe operating temperatures requires reliable cooling, making dependable water supplies an important part of many facility designs. Because many facilities operate around the clock, they require water infrastructure that is not only sufficient in volume but also highly reliable.
Cooling technologies vary considerably. Some designs rely heavily on water, while others reduce water consumption through more efficient cooling methods. As AI workloads continue to increase computing density, facility designers are evaluating technologies that balance energy efficiency, water use, and long-term operating costs.
Water demand varies by location, climate, cooling method, and local water resources. As a result, developers increasingly evaluate long-term water availability alongside power, connectivity, workforce, and land when selecting sites.
The Challenge for Fast-Growing Communities
Data centers are often built in regions experiencing rapid population and economic growth as well as increasing demand for housing and utility services. When planning water infrastructure, local municipalities must consider current and future water needs across various sectors.
Data centers become another major water user that communities must plan for alongside residential neighborhoods, manufacturers, schools, hospitals, agriculture, and future development. In many regions, the challenge is ensuring enough treatment and distribution capacity exists for tomorrow’s growth.
In drought-prone regions or those juggling competing water demands, utilities are increasingly looking beyond traditional freshwater sources to support new development without reducing long-term reliability for existing customers.
Expanding Supply Without Stressing Freshwater Resources
Meeting future demand doesn’t always require finding more freshwater supplies. Many communities are expanding supply by making better use of the water resources they already have. By diversifying water sources, they can strengthen water resilience while meeting data center demand without compromising supplies for residential, industrial, and agricultural users.
One of the most effective ways to achieve this is through water reuse. Every community generates wastewater, creating an opportunity to reclaim, treat, and reuse it for non-potable applications such as data center cooling. Reusing treated wastewater reduces demand on freshwater resources while supporting economic growth.
Brackish groundwater can also serve as an alternative resource in many regions. Many aquifers contain large volumes of brackish groundwater that is unsuitable for drinking because of the saline content. Advanced desalination technologies such as brackish water reverse osmosis enable communities to convert this underused resource into potable water, expanding available water supplies without withdrawals from traditional freshwater sources.
When combined with more efficient cooling technologies that reduce water consumption, alternative sources such as reclaimed water and brackish groundwater can support sustainable development. Rather than depending on a single source, many communities are building diversified water portfolios that combine traditional supplies with reuse, brackish groundwater, conservation, and other alternative sources.
Investments made to support data center growth can also strengthen long-term water resilience for residents, businesses, and future development, creating benefits that extend well beyond a single project.
Building Flexible Infrastructure for Future Growth
Predicting exactly when new demand will arrive is difficult. Communities benefit from infrastructure strategies that can expand alongside growth rather than requiring massive investments years before they’re needed. Scalable treatment systems allow utilities to add capacity in phases, aligning investment with actual demand while maintaining flexibility if growth projections change.
Decentralized treatment systems can also provide flexibility by placing treatment capacity closer to where it’s needed. Their prefabricated design allows additional treatment capacity to scale incrementally while helping reduce construction timelines compared to many conventional projects.
How communities deliver new infrastructure is evolving as well. Alternative delivery models, such as Water-as-a-Service® (WaaS®), can help utilities bring new treatment capacity online without waiting for lengthy funding and construction cycles, while maintaining the flexibility to expand as demand grows.
Economic Growth and Water Stewardship Can Go Hand in Hand
As AI and digital infrastructure continue expanding, water planning will become an increasingly important part of economic development. Communities that diversify water supplies, invest in flexible infrastructure, and plan for long-term resilience will be better positioned to attract new investment while protecting reliable service for residents and existing businesses.
