SE Lambert and 19th Main Replacement

Engineering And Design
The Water Bureau is investing in Sellwood to replace 4,800 feet—just under a mile—of an aging water main (pipe) along SE Lambert and 19th Ave. The existing main was installed in 1927, and has had multiple breaks. This new pipe will make your water service more reliable and improve water quality.

Project Overview

As part of our ongoing investment in southeast Portland’s water supply, the Water Bureau plans to replace 4,800 feet—just under a mile—of an aging water main (pipe) along SE Lambert Street and SE 19th Avenue.

This map shows the construction area on SE 19th Avenue between SE Marion and SE Lambert Streets, on SE Lambert between SE 19th and SE Milwaukie Avenues, and a short stretch of pipe in SE Milwaukie where SE Lambert jogs a few feet to the north.


The existing main was installed in 1927 and has had six breaks in the last ten years. The new pipe will reduce the frequency of breaks and improve water quality.


  • SE 19th Avenue from SE Marion Street to SE Lambert Street
  • SE Lambert Street from SE 19th to SE Milwaukie Avenue
  • SE Milwaukie Avenue from SE Lambert Street to SE Lambert Street (Lambert Street jogs a half block north/south at SE Milwaukie Avenue)


The project is currently being designed. The design process will continue through 2021. Construction is expected to begin in late fall 2021 or early winter 2022.

What to Expect

In 2021, you may see Water Bureau employees in the street inspecting the project area to improve the initial design and plan for construction work.
