SE 2nd and SE 3rd Avenue Sewer Replacement and SE 6th Avenue and Alder Relief Structure

map of SE 2nd and 3rd sewer projectEnvironmental Services has finished two inner southeast Portland sewer projects (see maps):

  1. Replace 100-year old public sewer pipes that are in poor condition on SE 2nd and 3rd avenues between Alder and Stark and restore the intersection of SE 3rd and Alder.
  2. Install an underground vault on SE Alder between SE 6th and Grand to divert combined sewage during heavy rain storms.

This project makes the sewer in the area function better, reduces basement backups and improved the intersection of SE 3rd and Alder for vehicles, bicycles and pedestrians.

Maintaining Portland's Sewer System

Over one-third of Portland’s 2,500 miles of sewer pipes are more than 80 years old. Projects to replace or repair aging sewers are important for protecting water quality, public health, and the environment.
