Brown and Caldwell to Lead Improvements to Water Treatment Facility

BOULDER, CO — The City of Boulder, Colorado, has engaged Brown and Caldwell to provide professional engineering and design services at the city’s Betaasso Water Treatment Facility (BWTF) to address aging infrastructure and improve disinfection and corrosion control systems.

Built in 1964 and extensively renovated in 2018, the BWTF is Boulder’s primary drinking water treatment facility, with a capacity of 40 million gallons per day (MGD). The conventional surface water treatment plant is located in the foothills west of Boulder. It treats water from North Boulder Creek and Barker Reservoir.

The findings of the city’s 2019 Asset Inventory & Maintenance project consistently provide high-quality service to water customers and point to several obsolescence and critical components at the BWTF that require capital repair and replacement, regular maintenance and improvements to meet the city’s service levels. comply.

“The City is committed to maintaining and improving the quality of life in Boulder by planning for future needs, promoting environmental quality, building and maintaining municipal infrastructure, managing public investment, and protecting of health and safety,” said City of Boulder Public Works Engineering Services Manager Stephen Grooters. “This important project will play a key role in achieving service levels, maintaining a reliable water supply and avoiding infrastructure constraints related to citywide development, redevelopment, sustainability and resilience goals.”

The improvements will increase resiliency and improve redundancy for pH and corrosion control systems, disinfection, backwash and primary water supply lines of the facility.

Upon completion, the facility will be equipped with dual 20 MGD treatment trains, allowing large infrastructure to be decommissioned for future maintenance or emergencies without service interruptions while continuing to meet increasingly stringent regulations.

“We look forward to working with the city and its stakeholders to provide solutions to maintain a resilient, safe and reliable water supply that follows industry best practices,” said Brown and Caldwell Project Manager Laurie Sullivan.

Construction is scheduled to be completed in the spring of 2024.
