Virginia data center growth prompts call for improved water planning
Virginia's rapid data center expansion necessitates more intentional water planning, particularly regarding rainwater harvesting. State Senate Bill 521, aimed at encouraging rainwater harvesting in large data centers, led to a study by the Virginia DEQ and VDH to inform future policy decisions. The article emphasizes that proactive water infrastructure decisions are critical as development continues.
As Virginia continues to lead the nation in data center development, Leslie Jarvis, founder of the Society for a Secure and Sustainable Water Future, argues that water planning for these facilities can no longer be an afterthought. Jarvis highlights that while considerable effort goes into planning electrical, transportation, and communication systems, water is often treated merely as a utility connection rather than a critical design decision.
Earlier this year, the Virginia General Assembly introduced Senate Bill 521, legislation intended to encourage the consideration of rainwater harvesting in large data center developments. Rather than immediately advancing the bill, lawmakers directed the Virginia Department of Environmental Quality (DEQ) and the Virginia Department of Health (VDH) to conduct a study on the potential impacts of large-scale rainwater harvesting. Jarvis supports this decision, emphasizing the need for good policy to be informed by sound science, but also stresses the urgency required given the ongoing pace of development.
The article points out that rainwater harvesting, when properly designed, can reduce stormwater runoff, supplement water uses, lessen demand on potable water, and provide resilience during water stresses. While not a replacement for municipal systems, it offers a practical tool for sustainable infrastructure. Jarvis concludes by noting that Virginia's approach to water infrastructure decisions will shape communities for generations, urging for thoughtful planning and timely action as new infrastructure continues to be built today.
