Eight years ago, concerns about heavy industrial activity’s pressure on local water supplies in Weld County were met with dismissive backlash. Suggestions that raising such issues equated to opposing vital industries ignored the long-term risks to water security. Today, those warnings are starkly relevant as Weld County grapples with severe groundwater and surface water depletion, particularly in areas like Firestone, where the St. Vrain Water Treatment Plant faces an impossible task: meeting less than half of the town’s projected 2030 demand. The plant, currently operating at just 1.5 million gallons per day, struggles to sustain even that output, casting doubt on its planned expansion to 5 MGD. The Colorado River Basin’s loss of 28 million acre-feet of groundwater—equivalent to the volume of Lake Mead—is a regional crisis, yet local officials continue to celebrate awards like “Best of the Best” for tap water taste without addressing the underlying scarcity.
Now, a new industrial pressure point has emerged: AI data centers, which demand millions of gallons of water daily for evaporative cooling systems. These systems don’t operate in closed loops; the water they consume evaporates into the atmosphere, often dispersing beyond local watersheds. While some facilities tout partial closed-loop designs, the reality is that heat dissipation still requires external water use, ensuring that local supplies bear the brunt. This is happening in Weld County, where the industrial water burden is already unsustainable. The county ranks fourth in U.S. oil and gas production, a sector notorious for its water intensity. Adding AI data centers, which promise 20 years of sales tax exemptions under Colorado’s HB26-1030, risks pushing the county past a critical threshold. The bill’s language—framing these facilities as “renewable-powered”—obscures the water and energy realities, leaving residents to navigate deceptive legislative framing.
The human cost of this oversight becomes clearer with wildfire season approaching. Water scarcity doesn’t just mean shorter showers or browning lawns; it means ecosystems under strain, fire risks escalating, and communities left vulnerable. Residents are being urged to look beyond partisan divides and recognize that an AI data center proposal in Weld is a statewide issue. Opposition is already forming in local Facebook groups, and the Weld County Commissioners have extended the review period for the proposed regulatory ordinance to April 6. This isn’t about rejecting technological progress—it’s about ensuring that progress doesn’t come at the expense of the essentials. As one environmental health specialist noted, “Technology can be a wonderful tool, but AI is quickly crossing red lines on many fronts: environmental, security and social.” The question now is whether Weld County will act before the trickle becomes nothing at all.
