A Sewer Infrastructure Improvement Project

Project Update


 Sewer installation on Neff Road between Medical Center Drive and 27th Street is nearly complete.  Beginning April 11th, work crews will return to night work (7:30 pm to 6:30 am) to install pipe in the Neff Road – 27th Street intersection.  This phase of the work is anticipated to last about 6 weeks.  Flaggers will be present during the night operations to guide travelers around the work area safely.  The intersection will open up at 6:30 each morning to normal signal operations, except for the continued closure of westbound Neff between Medical Center Drive and 27th Street. (See Daytime Detour Map)  Access to the hospital from the east remains via Medical Center Drive or Conners Avenue.  Big blue hospital signs direct travelers to both access points.

See Detour Map

Work continues throughout the 27th Street corridor including isolated areas of paving!  While there remains a lot of work still to come, approximately 5,000 feet of the pipe has been installed in this construction phase.  There will be several traffic shifts as the work continues.  Please travel slowly in these areas for your safety and for the safety of the workers.

SEI Project Purpose

The City of Bend protects drinking water sources, public health, and the environment by conveying and treating wastewater from throughout the City. The Southeast Interceptor (SEI) is a multi-purpose infrastructure addition to the City’s sewer collection system and 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.

SEI provides much needed enhancements to the city’s sewer collection system. Benefits include:

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