27th Street Sewer Line Project

Crews continue to work throughout the 27th Street corridor.

  • All traffic signals north of Hwy 20 are fully functional.  ODOT is scheduled to reset and optimize the timing cycles.
  • Nearly all of the new paving is complete north of Hwy 20.  Minor intersection paving at side street locations is expected in the coming weeks as well removal and repaving at the Neff /27th Street intersection (night work).
  • Landscaping work north of Forum Drive is anticipated in the coming weeks.  This will require closure of the “fast lanes”.  Please watch for lane shifts.
  • Work at the Bear Creek Road / 27th Street intersection including a pipe connection, signal work, and paving is anticipated in September.
  • Work continues on the last section of sewer pipe which is in Reed Market Road.  Northbound traffic is detoured at Ferguson Road to 15th Street and north to Hwy 20. 

Reopening Reed Market Road and the intersection with 27th is anticipated in late September.  Stay tuned for further updates.



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


Primary contact will be through DOWL, a local engineering and construction management firm. The City has contracted with DOWL to provide construction management and public outreach services for the SEI construction projects.
