Bend’s sewer collection system is near capacity. This project will provide much needed relief in the north area of town.

OB Riley/Third Street

Repaving efforts are now complete within these sections of the project, expect minor delays as the finishing pieces are completed

Butler Market Railroad Coordination Work

The North Area Sewer project is completing sewer work between Third Street and Second Street on Butler Market Road. Two-way traffic will be maintained during this construction. Detours for closed sidewalks and bike lanes are currently in place.

Nels Anderson Gravity Main

No traffic impacts anticipated in this section. A boring under US97 is underway.


In some areas of Bend, existing sewer pipes routinely approach overflow levels. In parts of the city it is difficult for Bend to add any major new employer or residential development.

In addition to providing much needed relief in the north area of town, this project will increase capacity for additional development. By rerouting force main discharge from the south, this will help reduce the amount of sewer flow sent to the far north end of the collection system.

This project is funded by the Clean Water State Revolving Fund (CWSRF).

Project includes design and construction of the following sewer collection system features:

  • Force main construction south from Sawyer Park Lift Station on O.B. Riley/3rd Street and east on Butler Market Road connecting to the existing gravity main near 4th Street.
  • Gravity system upgrades between Nels Anderson Rd. and N. HWY 97.
  • Reconfigure diversion at Mervin Samples Road to balance flows and provide additional north end capacity.


  • Preliminary Design: Complete
  • Final Design: Completed Summer 2015
  • Construction: Spring 2017 through year end


The Collection System Master Plan Team developed several alternative solutions to address existing capacity challenged portions of the collection system. The solution sets were presented to the Sewer Infrastructure Advisory Group (SIAG) for consideration. SIAG recommended that the design for the North Sewer Force Mains be implemented as soon as possible.
