Charlotte's Water Use Strategies Signal New Challenges for Data Centers

Executive Summary

Charlotte's city council is actively updating water use policies that carry direct operational implications for data center developers in the region. Deputy City Manager Alyson Craig presented the latest measures to the council's Transportation, Planning & Development Committee on August 3, signaling that sustainability concerns are moving from background policy debate into front-line regulatory action. Developers who treat water consumption as an afterthought in site planning will face growing friction — on permitting timelines, community approval, and long-term operational feasibility. Sustainable infrastructure providers stand to gain as demand for water-efficient cooling solutions increases. The InfraSale takeaway: if you are sourcing or developing data center sites in the Charlotte metro, water use strategy is no longer optional due diligence — it is a project viability question.

What Happened

On August 3, Deputy City Manager Alyson Craig delivered an update to Charlotte City Council's Transportation, Planning & Development Committee covering the city's evolving water use strategies. The briefing addressed how large electricity and water consumers — including data centers — fit into the city's broader sustainability and resource planning framework.

The presentation covered measures under consideration or already in motion, though specific policy thresholds, gallon-per-day limits, or named regulatory instruments were not detailed in the available reporting. What is clear is that city leadership is treating data centers as a distinct category of infrastructure with outsized resource demands that require dedicated policy attention.

The timing is not coincidental. Charlotte has seen growing interest from hyperscale and colocation operators drawn by its fiber connectivity, labor market, and relative land affordability compared to Northern Virginia. That growth trajectory is now intersecting with a municipal government increasingly focused on resource sustainability.

Why This Matters

Water is the unspoken variable in data center site selection. Most public conversation focuses on power capacity and interconnection — but a hyperscale facility can consume millions of gallons of water per day through evaporative cooling towers. When a municipality starts tracking and regulating that consumption, the operational calculus for every project in its pipeline changes.

Charlotte's action fits a national pattern. Industry context: cities including Phoenix, Mesa (Arizona), and several Pacific Northwest municipalities have already moved to restrict or surcharge water-intensive data center operations, forcing operators toward closed-loop cooling, air-side economizers, or more expensive water recycling systems. Charlotte appearing on that list raises the stakes for the Southeast corridor as a whole.

For developers, the second-order effect is timeline risk. Regulatory uncertainty — even at the discussion stage — can stall permitting, trigger additional environmental review, and complicate PPA negotiations with utilities that may face their own resource planning constraints. Investors pricing deals on 18-to-24-month development timelines need to factor in regulatory lag now, not at close.

The broader signal is that local governments are no longer passive participants in the data center boom. They are increasingly using permitting leverage and utility coordination to extract sustainability commitments — or simply to slow development until those commitments are on paper.

Power & Interconnection Impact

Water and power are functionally linked inside a data center. Cooling systems — which account for a significant share of total facility power draw — are often the primary water consumers. If Charlotte moves to cap or penalize water use above certain thresholds, operators will need to shift toward air-cooled or liquid-cooled server architectures, both of which carry different power demand profiles.

Industry context: transitioning from evaporative cooling to air-side economization or direct liquid cooling can increase peak electrical demand per rack by 10–20%, depending on facility design and climate conditions. That increase flows directly into interconnection queue calculations and substation capacity planning at Duke Energy Carolinas, the primary utility serving the Charlotte market.

Developers evaluating sites in Mecklenburg County and adjacent counties should engage Duke Energy early on both water and power resource planning. A facility redesigned around alternative cooling to satisfy city water policy may need more MW from the grid than the original design assumed — a fact that needs to be in front of the interconnection team before queue position is established.

Land, Zoning & Permitting Impact

Zoning and permitting are the immediate pressure points. Charlotte's council review process signals that data center projects may face additional layers of scrutiny — specifically around water use documentation, sustainability plans, and community impact assessments — before receiving development approvals.

Assumption: projects already in the permitting pipeline but not yet approved could be subject to revised conditions if new water use ordinances are adopted before their approval dates. Developers with sites in early-stage entitlement should consult with local land use counsel now to assess exposure.

The land development market in Charlotte's surrounding counties — Cabarrus, Gaston, Union — may see increased interest from operators seeking to site projects outside Mecklenburg County's direct regulatory reach. That dynamic can compress available land inventory and push prices in those submarkets, particularly for parcels with existing utility infrastructure.

Zoning law evolution is also likely. Industry context: municipalities that begin with water use reporting requirements frequently follow with zoning overlays that restrict water-intensive uses in certain districts or require on-site water recycling as a condition of special use permits.

Investment Takeaway

Sustainability-compliant facilities command a premium. Data centers built with closed-loop or low-water cooling systems are increasingly attractive to tenants, lenders, and offtakers with ESG mandates. That premium will widen as regulatory pressure increases.
Timeline risk is repricing deals in Charlotte. Investors underwriting projects on near-term completion assumptions should build regulatory buffer into their models. A 6–12 month permitting delay caused by water use review is a realistic downside scenario.
Adjacent-county land is worth another look. Sites in Cabarrus, Gaston, and Union counties may offer near-term regulatory arbitrage — but that window closes quickly once the Charlotte policy direction becomes clear and neighboring municipalities follow.
Water-efficient cooling technology providers benefit directly. Companies offering air-side economization, direct liquid cooling, or on-site water recycling systems are well positioned to capture demand from operators forced to redesign facilities.
Operators with established sustainability reporting have a structural advantage. Hyperscalers and large colos with existing water use disclosure frameworks will move through Charlotte's approval process faster than smaller operators building that infrastructure from scratch.

InfraSale Market Angle

For developers sourcing sites in the Charlotte market, the message from city hall is clear: water use is now a project-level underwriting variable, not a facilities management afterthought. Site feasibility analysis must now include water availability, local utility supply capacity, and a credible plan for meeting whatever sustainability thresholds the city ultimately codifies.

Investors evaluating Charlotte-area data center projects should ask developers specifically how water use policy risk is accounted for in the project pro forma. Deals that don't address this are carrying unpriced regulatory risk.

Landowners with sites in the Charlotte metro that include water access rights, reclaimed water connections, or proximity to industrial water infrastructure have a differentiating asset. That attribute should be surfaced explicitly in any site marketing materials.

FAQ

What are the new water use regulations in Charlotte for data centers?

As of the August 3 council committee update, Charlotte has not yet finalized specific numeric thresholds or ordinance language. Deputy City Manager Alyson Craig presented the city's evolving water use strategies to the Transportation, Planning & Development Committee, signaling active policy development. Developers should monitor Charlotte City Council proceedings closely for formal rulemaking announcements in the coming months.

How will these regulations affect data center operations in Charlotte?

If the city moves toward water use caps, surcharges, or mandatory reporting requirements, operators relying on evaporative cooling towers will face the most direct impact. Facilities may need to retrofit or redesign cooling infrastructure — potentially increasing capital costs and peak power demand. Projects still in the design phase have the most flexibility to adapt.

What should developers consider regarding water sustainability when siting a data center in Charlotte?

Developers should evaluate cooling system architecture early — specifically whether evaporative, air-cooled, or liquid-cooled designs align with likely regulatory requirements. Securing water rights, assessing reclaimed water availability, and engaging with Duke Energy Carolinas on combined power-and-water resource planning are all steps that should happen before permitting applications are submitted.

Will Charlotte's water policies affect data center investment returns?

Assumption: projects that require cooling system redesigns or face permitting delays will see increased development costs and extended timelines, both of which compress returns. However, assets delivered with credible water sustainability profiles may command higher valuations from institutional buyers and tenants with ESG requirements, partially offsetting those costs.

Are other Southeast cities likely to follow Charlotte's lead?

Industry context: once a major metro in a growth market moves toward formalizing data center resource policies, neighboring cities and counties often respond with their own frameworks within 12–24 months. Developers active across the Southeast Carolinas, Georgia, and Tennessee submarkets should treat Charlotte's process as an early indicator of regional regulatory direction.
