Mission Trunk Sewer Project

Mission Trunk Sewer Project


The Sacramento Area Sewer District (SASD) is working on the Mission Trunk Sewer Project to return a critical stretch of sewer pipe to optimal operating performance, thereby ensuring continued reliable sewer service for the community.

The Mission Trunk sewer generally follows the Mission Avenue corridor, beginning upstream near American River College and ending downstream near the American River.

Now nearly complete, the project has been done in three phases (see Overview Map), with completion anticipated by March 2021. 

During the work, SASD has maintained uninterrupted sewer service and has taken measures to minimize construction impacts, including traffic slowdowns, parking restrictions, and lane or road closures. 

During this time of the COVID-19 pandemic, please be assured construction crews are taking all necessary precautions to keep themselves and the community safe. We appreciate your patience and cooperation as we work to complete this essential project for the Sacramento region.
