NW Flanders Sewer Capacity Project

COVID-19 webbanner Sign up for email updates

Updated November 18, 2020

Environmental Services has finished construction to replace and upsize 540 feet of 130-year-old public sewer pipes in NW Flanders Street between NW 12th and 14th avenues. The sewer improvements will increase sewer capacity, alleviate basement sewer backups and street flooding, and help protect public health and the environment.

The sewer pipes were constructed as part of the Flanders Crossing pedestrian bridge project being designed and built by the Portland Bureau of Transportation (PBOT).
