Site work for a water / sewer project in Bozeman, Montana. Conceptual plans call for site work for a water / sewer project.

This project will either replace and upsize, or parallel certain portions of the sanitary sewer along the 11,500 feet length of the existing North Frontage Road Interceptor. The North Frontage Road Interceptor supports large portions of the City's southeast and eastern sewersheds. The extents of the project is generally located between Springhill Road and Bridger Drive. Portions of the interceptor have been shown to have an increased risk of failure due to the age and condition of the asset while other segments have been identified in the City's hydraulic model to be near hydraulic capcaity during wet weather modeling scenarios. The project consists of two main components: first, the replacement of existing parallel trunk sewer, which includes the replacement and upsizing of the worst condition parallel interceptor main; second, the installation of a new parallel interceptor main along portions of the existing interceptor that currently only have a single segment of main. Overall, the project will provide the necessary improvements needed to increase system capacity to meet future buildout conditions while decreasing overall risk along the interceptor corridor. Lastly, the existing interceptor main that is not mitigated as part of the project will be inspected for current condition and either replaced or rehabilitated at a later date, thus utilizing the City's existing assets to their full expected life-cycle extent. The project will conform to the City's Wastewater Collection Facility Master plan. Engineering is scheduled in FY27 and construction in FY29. This project is included in the city's fy 2025-2029 Capital Improvement Program. As of January 22, 2025, further details regarding design and construction timelines have not been identified. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
