Boulder City Council Imposes 2-Year Gray Water Ban, Urgent Update

UPDATE: The Boulder City Council has just passed an ordinance imposing a two-year ban on the use of gray water through the city’s water utility, disrupting plans for residents hoping to utilize this eco-friendly resource. Gray water, which is recycled water from appliances like sinks and showers, can be repurposed for irrigation, providing significant water conservation benefits.

This urgent decision aligns with a 2024 Colorado state law that will take effect next year, permitting gray water systems in new constructions while allowing municipalities the option to opt out. While city officials recognize the importance of gray water in promoting sustainability, they believe this temporary ban is necessary to comply with upcoming regulations.

City staffers have outlined that implementing a robust gray water system involves comprehensive planning, including adopting new regulations, creating a permitting process, and ensuring rigorous inspections to prevent contamination of drinking water. They estimate that establishing a city-wide gray water system will require a minimum of two years and the allocation of two full-time equivalent positions.

The significance of this ban is underscored by the findings from a project conducted by CU Boulder, which reused gray water from the Williams Village dorm between 2013 and 2023. Surprisingly, the project conserved less water than anticipated, raising questions about the effectiveness of gray water systems in certain contexts.

In terms of public engagement, city staff have referenced efforts made for the 2023 water efficiency plan. However, this engagement has been criticized. Planning Board Chair Mark McIntyre expressed concerns in a memo, stating that the current ordinance is “too broad and blunt” and could criminalize behaviors that actually support sustainability goals. He urged for a more nuanced approach, advocating for broader stakeholder engagement before finalizing the ordinance.

As the city grapples with this critical issue, residents and stakeholders alike are encouraged to stay informed about the implications of this ban and the potential for future gray water systems. The Boulder City Council is expected to continue discussions on this topic in the coming months, with significant attention on how to balance regulatory compliance with environmental sustainability.
