Officials in Cheyenne, Wyoming, have tightened regulations governing wastewater disposal following a serious incident involving a contractor for Meta, the tech giant led by Mark Zuckerberg. The contractor allegedly discharged water contaminated with bacteria into the city’s sewer system during construction of a new datacentre, igniting concerns over environmental safety and public health.
Contamination Incident Uncovered
The contamination was detected in February during routine testing of wastewater released from the cooling system of the expansive datacentre, part of the controversial Project Cosmo located in the High Plains Business Park. The city’s water authorities identified Goat Systems LLC, a Delaware-based contractor, as responsible for the discharge. Following the incident, the Cheyenne Board of Public Utilities (BOPU) took immediate action, permanently revoking Meta’s permission to release any wastewater into the municipal treatment facilities, which recycle water for irrigation in public parks and spaces.
Frank Strong, manager of BOPU’s engineering and water resource division, revealed that the city has adopted a new policy prohibiting wastewater discharges from datacentres employing closed loop cooling systems. These systems, which circulate purified water to remove construction debris, were deemed insufficiently safe after the contamination incident.
Meta’s Response and Commitment to Local Safety
In response to the findings, Meta has mandated that its general contractor, Fortis, fully cooperate with local authorities to prevent any recurrence. The company expressed its commitment to being a “good neighbour” and reassured residents that the contamination, attributed to the naturally occurring Cupriavidus gilardii bacterium, posed no risk to drinking water supplies. Independent testing conducted by an environmental specialist revealed no traces of the bacteria in the potable water, alleviating immediate fears over public health.
Despite these assurances, the incident has heightened scrutiny over the environmental impact of datacentres, particularly in light of an escalating national debate regarding their resource consumption. In the United States, approximately 4,500 datacentres operate, some requiring up to 300,000 gallons of water daily—an amount comparable to the needs of about 1,000 households.
Growing Public Opposition to Datacentre Expansion
The bacteria incident has intensified existing public opposition to the Project Cosmo datacentre. Prior to this event, concerns had already been raised regarding the environmental integrity of the closed loop cooling systems employed by Meta and similar tech companies. Recent reports from outlets like the Cowboy State Daily highlight widespread apprehension among residents about the sustainability of such projects, particularly in a state like Wyoming, where water resources are finite.
In light of the incident, BOPU has implemented new regulations requiring datacentre operators to establish separate collection systems for water used in cooling processes. This water must now be directed to storage tanks for offsite disposal, rather than being released into the city’s sanitary sewer system.
Health Risks of Cupriavidus gilardii
While Cupriavidus gilardii is generally considered an “opportunistic pathogen,” it is primarily harmful to individuals with weakened immune systems. A study published in the International Journal of Infectious Diseases documented rare cases of severe infections linked to this bacterium, with only seven known instances of human infections. The bacterium was notably associated with a tragic incident involving a patient who succumbed to septic shock following a medical procedure.
Frank Strong voiced concerns regarding the potential health risks associated with aerosolising water that may contain pathogens. “The concern we have with our reuse system is we put it into aerosol, where we spray it on to the grass, and that increases the potential for health issues,” he remarked. However, he assured that the city’s irrigation programme has resumed now that the datacentre’s wastewater discharge has ceased.
Why it Matters
This incident serves as a stark reminder of the complex interplay between technological advancement and environmental stewardship. As communities grapple with the growing demand for datacentres, the need for stringent regulations and responsible practices becomes increasingly crucial. The actions taken in Cheyenne may set a precedent for other municipalities facing similar challenges, highlighting the importance of safeguarding public health while navigating the fast-paced evolution of artificial intelligence and technology. The outcome of this situation will likely influence future discussions about the balance between innovation and environmental responsibility, and the role of major corporations in local ecosystems.
