Project Background
The City of Boulder owns and operates two potable water treatment facilities that supply water to customers. These are the Betasso Water Treatment Facility (BWTF) rated at 40 million gallons per day (mgd) and the 63rd Water Treatment Facility (63rd WTF) rated at 16 mgd.
Initial construction of the 63rd WTF took place in 1969 to provide critical backup supply during times when BWTF is offline for repairs or emergencies. In addition, the facility is required for use of critical water rights from the western slope of the Colorado Continental Divide. Since the 63rd WTF construction, various expansion and improvement projects have been constructed to maintain service and the ability to meet more stringent regulations.
Overall, the facility has provided high-level service to city water customers but is aging and needs repairs. The focus of this project is twofold:
- Replacing major power supply and electrical components on the campus and to improve their reliability and redundancy, and;
- Repair and replacement (R&R) of the existing treatment process on campus called the high service pump station (HSPS).
The HSPS was built in 1969 and is the sole source of supply to the distribution system from the 63rd WTF. Minor repairs have been implemented over time, but the station is now at its end of useful life. The project also contemplates converting the existing power supply of the station to a lower voltage that is less hazardous and more easily maintained.
Latest Updates
January, 2024 - Progress is on-track and work is 80% complete. Upcoming work will focus on preparations and planning for an extended 12-week plant outage from February through April. The outage is necessary to safely construct high-voltage electrical gear and to modify major campus pipelines. Community members will see no service interruptions.
The projected project finish remains summer 2025.
Impacts
The public will see no service interruptions. This project was planned, designed, and contracted with a project-specific schedule to prevent impacts to city customers. The vast majority of work will be done in ways that permit the facility to remain in operation. The project schedule includes two primary outage periods of the 63rd facility both of which are off-season, winter-only shutdowns. During these periods and throughout construction all facility outages will be offset by increasing potable water production and delivery through the City’s Betasso Water Treatment Facility.
