What We're Doing

The City of Stillwater and Stillwater Utilities Authority is replacing and upsizing aging sewer lines and rehabilitating approximately 85 manholes throughout the City.

The 9,700 feet of sewer line replacement will be in the West College Addition neighborhood, located west of Jefferson Street and south of University Avenue. In addition, the sewer crossing near Eyler Ln will be replaced. The aging sewer lines have been subject to frequent repairs and surcharges. Phase 1 of the replacement project in the West College area was completed in 2013.

Anticipated Milestones

  • Anticipated Date (Design): Design began December 2018
  • Anticipated Date (Construction): Late 2021
  • Anticipated Date (Completion): FY2022
