In a significant move reflecting growing environmental concerns, Wyoming officials have tightened wastewater regulations following an alarming incident involving a contractor for Meta, the tech giant founded by Mark Zuckerberg. During the construction of a new artificial intelligence datacentre, contaminated water containing bacteria was improperly discharged into public sewers, prompting immediate action from local authorities.
Incident Sparks Regulatory Changes
The situation unfolded in February during routine tests of wastewater from the cooling systems associated with the expansive datacentre known as Project Cosmo, located in Cheyenne’s High Plains Business Park. Authorities discovered the presence of Cupriavidus gilardii, a bacterium that, while naturally occurring, can pose health risks to individuals with compromised immune systems. The Wyoming Tribune Eagle first reported on the contamination, which has since led to the Cheyenne Board of Public Utilities (BOPU) implementing stringent new rules regarding wastewater management for similar projects.
The contractor responsible for the contamination, Goat Systems LLC, based in Delaware, has faced scrutiny as a result. In response to the incident, Cheyenne officials have permanently revoked Meta’s permission to discharge wastewater into the city’s treatment facilities, which play a crucial role in recycling water for public irrigation.
Meta’s Commitment to the Community
In a statement, Meta expressed its commitment to being a responsible community member. The company has instructed its general contractor, Fortis, to work closely with the BOPU to prevent any future occurrences. While Meta confirmed that the contaminated water did not impact drinking supplies, they acknowledged the seriousness of the situation. An independent environmental assessment commissioned by Fortis found no traces of the bacteria, highlighting the complexities surrounding such construction projects.
Erin Lamb, BOPU’s administrative and public affairs coordinator, indicated that a press conference would be held soon to address the issue further, although details remained sparse as public sentiment continued to grow against Project Cosmo.
Growing Opposition to Datacentre Projects
This incident has heightened existing tensions regarding the construction of large-scale datacentres, which many critics argue place excessive demands on local water and energy resources. Data Center Map estimates that the United States is home to nearly 4,500 datacentres, some of which consume upwards of 300,000 gallons of water daily—equivalent to the needs of approximately 1,000 households.
Public opposition to Project Cosmo had already been mounting prior to the contamination incident. Local activists and residents have raised concerns about the environmental impact of closed-loop cooling systems, which are often employed by major tech companies, including Meta. These systems, while designed to reduce water usage, have come under fire for potential safety and integrity issues.
New Regulations for Wastewater Management
In light of the recent events, the city of Cheyenne has enacted new regulations that require companies using closed-loop cooling systems to establish separate collection systems. This means any water from cooling equipment or related drains must be directed into storage tanks for offsite disposal, rather than being released into the city’s sanitary sewer system. Frank Strong, BOPU’s engineering and water resources division manager, remarked on the increased risks associated with aerosolising water during irrigation, underscoring the importance of stringent oversight.
Cupriavidus gilardii, while not frequently associated with severe health issues, has been linked to rare but serious infections. A study published in March 2026 detailed a case of septic shock following a patient contracting this bacterium during a medical procedure, drawing attention to the potential dangers posed by such contaminants in community water supplies.
Why it Matters
The contamination incident at Meta’s construction site serves as a critical reminder of the environmental responsibilities that accompany the expansion of technology infrastructure. As the demand for datacentres continues to rise, it is imperative that both companies and regulatory bodies prioritise the protection of local resources and public health. The actions taken by Wyoming officials not only reflect a commitment to environmental stewardship but also highlight the need for ongoing scrutiny of the tech industry’s impact on communities. The outcome of these new regulations could set a precedent for how similar projects are managed across the nation, influencing the balance between technological advancement and ecological sustainability.
