Over one-third of Portland’s more than 2,500 miles of sewer pipes are more than 80 years old. Projects to replace or repair aging infrastructure and restore Portland’s watersheds protect public health and the environment. These projects reduce the possibility of sewage releases into buildings, streets, and greenspaces.
Environmental Services has sewer, stormwater, and watershed restoration projects throughout Portland. These projects could be in either planning, design, or construction. Locate projects using the map below.
