Mission Trunk Sewer Project

Mission Trunk Sewer Project


The Sacramento Area Sewer District (SASD) has completed all major work on the Mission Trunk Sewer Project, which has returned 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.

The project was done in three phases (see Overview Map), with completion in March 2021. Final paving activities are currently underway.

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.
