Boulder Utilities outlines multi-year pipeline and water treatment improvement plan

The Boulder City Water Resources Advisory Board meeting on May 19, 2025, highlighted significant ongoing projects aimed at improving the city’s water infrastructure, which is crucial for ensuring reliable water supply and quality for residents.

One of the key discussions centered on the Barker gravity pipeline rehabilitation project, which is expected to take four more years to complete. This project is essential for maintaining the integrity of the water supply system, as the pipeline is aging but still functional. The board emphasized the importance of conducting thorough analyses on various facilities to prioritize upgrades effectively.

Another major topic was the Boulder Canyon and Penn stock pipeline, which will follow the Barker project. The board noted that the rehabilitation efforts are strategically scheduled during winter months to minimize disruption during peak water demand seasons. This careful planning reflects the city’s commitment to maintaining a reliable water supply while addressing aging infrastructure.

The meeting also touched on the city’s water treatment facilities, including the Boulder Reservoir Water Treatment Plant and the Potassa Water Treatment Plant. Upgrades to these facilities are underway, focusing on essential components like the chemical feed system and backwash tanks, which are nearing the end of their useful life. These improvements are vital for ensuring that the water remains safe and potable for the community.

In addition to water supply and treatment, the board discussed the wastewater system, particularly the ongoing sanitary sewer lining program initiated after the 2013 floods. This program aims to reduce inflow and infiltration issues, with a goal to complete the lining of remaining pipes by 2035. The board is also prioritizing equity in project planning, ensuring that underserved neighborhoods receive necessary upgrades.

The meeting concluded with a focus on stormwater management and flood prevention efforts. The city is working on enhancing its stormwater conveyance systems to better handle local storms and reduce flooding risks. A notable project mentioned was the rain garden at Fifteenth and Palm, which serves dual purposes of improving drainage and water quality.

Overall, the discussions at the meeting underscored Boulder’s proactive approach to managing its water resources, ensuring that infrastructure improvements align with community needs and environmental considerations. As these projects progress, residents can expect enhanced water quality and reliability, contributing to the city’s long-term sustainability goals.
