Project Overview

Boulder strives to provide customers with safe and high-quality drinking water. We use waterlines, also known as water service lines or main water lines, to supply drinking water to our community.

To continue providing safe, clean water, we must replace older waterlines once they reach the end of their functional lifespan. The previous waterlines along 63rd Street were outdated, difficult to maintain and vulnerable to failure. Replacement before they broke down was essential to provide water for Boulder.

Both phases of the project replaced aging infrastructure with newer, more easily maintained waterlines to improve water distribution resilience. One of the new waterlines is also twice as large as the previous waterline, helping provide improved drinking water service for the Gunbarrel community.

Construction Impacts

63rd Street is open. The multi-use path is also open.

Late Spring Travel Impacts

Resurfacing will be finalized in the spring. View travel impacts and suggested detours on the city’s Cone Zones map. Scheduling is weather-dependent and may change.

Nearby Projects

Community members in the area may also experience nearby travel impacts from state and county transportation projects, unrelated to this project. Funding and maintenance lifecycles affect the timing of major infrastructure projects, which often take years to complete and can then overlap with other construction projects.

We are working to coordinate traffic impacts and construction wherever possible with local and regional agencies, as well as affected residents and businesses, to reduce impacts. While impactful, the project timeline has been accelerated to reduce the length of construction by several months.

We know these impacts can be very frustrating and we take project impacts seriously. Thank you for your patience as the city works to replace vital drinking water infrastructure in the Gunbarrel neighborhood.

The first project phase replaced a 12-inch and 30-inch waterline. The second phase of the project replaced an aging 24-inch pipeline with a new, larger 30-inch pipeline for better water flow and resilience. This project is funded by the city's Utilities Fund.
