15th St. Waterline Repair
A major waterline located beneath 15th St., just south of Main St. (CO 392), is a critical component of the town’s core water infrastructure and has served the community reliably for decades. As with many legacy systems, aging materials and increased demand over time can impact performance and long-term durability.
Proactively replacing this waterline is an important step in strengthening the overall water system. The project will improve reliability, support consistent water pressure and enhance fire protection capabilities in the area. It will also help reduce the likelihood of unexpected breaks, minimize service disruptions and lower ongoing maintenance costs associated with aging infrastructure.
By investing in this upgrade now, the town is taking a forward-looking approach to ensure safe, efficient and dependable water service for residents, businesses and visitors; both today and as the community continues to grow.
On Thursday, May 21, the Town of Windsor held a virtual public information session for those who will be impacted by this road work, with another held on Wednesday, May 19 that can be viewed below:
