27th Street Sewer Line Project

Crews continue to work throughout the 27th Street corridor.

  • Work at the Medical Center Drive – 27th Street intersection has the signal turned off.  Left turns are restricted as is east-west traffic. North-south traffic is open and right turns are available. Pedestrians are detoured north to Neff Road or south to Mary Rose Place.
  • Two crews are working south on 27th Street near Sunburst Court and Capella Place.
  • Concrete and electrical crews at working at various intersection corners constructing new pedestrian ramps and signals.

Looking ahead, beginning in July, Reed Market Road will be closed. Traffic will be detoured around via Ferguson Road. Stayed tuned for further information.

27th St Sewer Line: What Happens During Construction


The City of Bend protects drinking water sources, public health, and the environment by conveying and treating wastewater from throughout the City. The SEI will provide relief to capacity issues in southwest, southeast, northeast, and central areas in Bend. This project is noted by the Sewer Infrastructure Advisory Group (SIAG) as “the linchpin for solving Bend’s sewer problems” and has been approved by City Council. There are several segments of design and construction necessary to complete this sewer infrastructure improvement project.

Benefits include:

  • Increase existing collection system capacity by routing flow away from the downtown core area
  • Provide the opportunity to decommission several sewer pump stations
  • Provide the availability of gravity sewer service to hundreds of homes that are currently on septic systems
