SW Terwilliger Boulevard Sewer Project

Sign up for email updatesConstruction is underway on an Environmental Services project to install 7,600 feet of eight-inch gravity sewer in SW Terwilliger Boulevard from SW Northgate Avenue to Highway 43. SW Terwilliger Boulevard will be closed (see map) for the duration of the project. Construction began in December 2016 and is anticipated to continue until August 2017. The new sewer will connect to the 30-inch Tryon Interceptor sewer, which carries sewage to the Tryon Creek Wastewater Treatment Plant in Lake Oswego. This improvement to Portland’s wastewater collection system will help protect water quality, public health, and the environment.
