Flagstaff City Council's Budget Retreat on April 25, 2025, spotlighted urgent discussions surrounding the city's wastewater treatment infrastructure, emphasizing the need for significant investment to accommodate future growth. Council members expressed concerns about the aging Rio wastewater treatment plant, which is nearing its capacity and could face compliance issues if not upgraded.

During the meeting, officials highlighted that the current plant, designed for a lifespan of 20 years, is now 45 years old. Failure to address these issues could lead to severe sanitary problems, including potential sewage overflow into local waterways. "If we did nothing, you're gonna hit our capacity in the near future as population continues to increase," warned one council member, underscoring the critical nature of the situation.

The council is considering a new facility projected to cost between $300 million and $400 million, with discussions on funding strategies already underway. Officials noted that relying solely on rate revenues would not suffice, indicating a need for creative financing solutions, including grants and low-interest loans. "We're going to need help on it," one member stated, reflecting the consensus that proactive measures are essential.

As the city anticipates continued population growth, the urgency to act is clear. The council is looking at a timeline that could see design work starting in the next 7 to 10 years, with construction potentially beginning shortly thereafter. "We have to have the discussion now," emphasized a council member, reinforcing the importance of planning for the future.

The meeting concluded with a call for further discussions on funding strategies and project timelines, as the council prepares to tackle these pressing infrastructure challenges head-on.
