Pennsylvania’s Data Center Strategy: Strong Progress on Energy—But Water Can’t Be an Afterthought

Pennsylvania is taking meaningful steps to prepare for the next wave of digital infrastructure.

With the passage of House Bill 1834 in the Pennsylvania House of Representatives, lawmakers have shown a clear commitment to protecting ratepayers from the rising electricity demands driven by data centers and artificial intelligence. By tasking the Pennsylvania Public Utility Commission with developing regulations, the state is proactively addressing one of the most pressing challenges tied to this growth: energy cost allocation.

This is thoughtful, forward-looking policy—and it deserves recognition.

But as Pennsylvania positions itself to compete in the AI and data center economy, there is another critical resource that must be part of the conversation: water.

The Missing Piece: Water Usage and Community Impact

Modern data centers, particularly those supporting AI workloads, rely heavily on water for cooling. While energy consumption often dominates headlines, water usage is equally consequential—especially for local communities.

Unlike electricity, which is distributed across regional grids, water impacts are deeply local.

Communities that host data centers may face:

• Increased demand on municipal water systems

• Rising water and wastewater treatment costs

• Potential rate increases for residents and small businesses

• Strain on agricultural water access in rural areas

• 
  

In a state like Pennsylvania—largely land-locked and reliant on rivers, aquifers, and local water systems—these pressures are not theoretical. They are immediate and community-specific.

Economic and Environmental Risks

There are two major areas of concern that deserve greater attention:

1. Economic Impact on ResidentsIf water infrastructure must be expanded or upgraded to support large-scale data centers, who pays? Without clear policy guardrails, there is a risk that local ratepayers could shoulder increased costs—similar to the concerns HB 1834 seeks to address on the energy side.

2. Environmental and Agricultural ImpactWastewater discharge and runoff present another layer of risk. If not carefully managed and transparently reported, contaminants could affect:

• Local drinking water supplies

• Soil quality

• Agricultural productivity

• 
  

For a state with a strong agricultural base, this is not a peripheral issue—it is central to long-term economic and environmental stability.

Why Transparency Matters

As Pennsylvania continues to attract data center investment, transparency around water sourcing and usage is essential.

Key questions policymakers and communities should be asking:

• Where is the water coming from—municipal systems, rivers, or groundwater?

• How much water will be used annually and at peak demand?

• How will wastewater be treated, discharged, and monitored?

• What protections are in place for surrounding ecosystems and farmland?

  
  

Clear, standardized reporting—and public accessibility of that information—will be critical to building trust.

A Path Forward

The good news is that Pennsylvania has already demonstrated leadership by addressing energy impacts early.

The next step is to extend that same level of rigor to water policy. That could include:

• Mandatory water usage disclosures

• Local impact assessments before project approval

• Protections to ensure communities are not burdened with higher costs

• Strong environmental safeguards for wastewater management

  
  

And finally...

Pennsylvania has an opportunity to lead—not just in attracting data centers, but in defining what responsible infrastructure development looks like. HB 1834 is a strong foundation. Now the challenge is to build on it. Because in the race to power the future, the question isn’t just how much energy we use—but how responsibly we manage every resource communities depend on.
