Inner Basin Waterline damage after the Pipeline Fire

Periodic Updates

  • August 2023
    • On the afternoon of August 1, spring water from the Inner Basin began to flow into the City of Flagstaff water distribution system for the first time since the Pipeline Fire and following monsoon season flooding events compromised the infrastructure. 
    • The repair and restoration of the waterline was the first repair priority for this project and was accomplished ahead of schedule. The repairs and construction work will continue through late fall 2024. Waterline Road remains impassable and is closed to motorized travel, recreationalists, and the public due to active construction and heavy equipment traffic.
  • January 2023
    • City Council approved the Design-Build Services Agreement with Hunter Contracting Co. and a Design Phase Services GMP1 contract (Guaranteed Maximum Price) in the amount of $189,694. GMP2, which will provide funding to complete the design portion of the project, is anticipated to come before Council for consideration in spring of 2023.
