The Broomfield City Council convened on July 16, 2025, to discuss several key infrastructure projects and updates, primarily focusing on water management and quality in the region.

The meeting began with an update on the Chimney Hollow Reservoir, which is set to store approximately 90,000 acre-feet of Windy Gap water, with Broomfield holding a significant 29.4% share. The first fill of the reservoir is scheduled to commence later this summer and will continue through 2027. However, concerns were raised regarding the detection of naturally occurring uranium in water samples collected behind the cofferdam during construction. This uranium is attributed to granite mining in the area, and ongoing monitoring of water quality is being conducted by Northern Water and engineering firms. It was emphasized that no water will be delivered from the reservoir until thorough assessments are completed to ensure safety.

The council also discussed the Northern Area water storage tanks, with plans to present a Guaranteed Maximum Price (GMP) to the council in December, following the adoption of the 2026 budget. Construction is expected to take 24 to 30 months. Additionally, the Mesa Booster Station project has been completed and is now operational, enhancing water pressure and supply in key areas.

A water meter replacement program is underway, transitioning from 12-year life meters to new ultrasonic technology expected to last up to 20 years. The program is projected to cost approximately $13.5 million, with 65 meters already installed.

Updates on waterline replacement projects revealed that the Westlake Community Waterline Replacement is 67% complete, with additional projects scheduled for completion by September 2025. The sewer collection and lift stations were also addressed, with ongoing rehabilitation projects and discussions regarding easements with local homeowners associations.

The council reviewed stormwater system programs, with rehabilitation efforts planned for various areas, including Maramonte Park and Broomfield Plaza. The water recovery facility is progressing, with phase one receiving construction approval from the Colorado Department of Public Health.

Lastly, the Great Western Reservoir was discussed, highlighting structural issues that need addressing by 2030. Preliminary risk assessments indicate that any construction alternatives would not pose a significant health threat to the community.

The meeting concluded with a commitment to continue monitoring and improving water quality and infrastructure, with follow-up meetings scheduled for August and further updates expected by October.
