City of Concord, California

Downtown Sewer Upgrade Project


Construction Manager Rod McHale
(925) 768-8057


The City of Concord plans to replace the main sewer lines in the downtown area. Many of the lines are clay pipe from the 40s and 50s and are undersized or failing. In order to ensure adequate service and capacity in one of the City's busiest areas, the lines need to be replaced. To offset the construction impact that a project of this magnitude will have on residents and businesses, the project will be divided into three separate phases over the next three years.

In addition to replacing the sewer lines, the City is coordinating with the Contra Costa Water District to make improvements to their lines at the same time. When all of the improvements are complete, the streets will be repaved and ADA upgrades made to adjacent sidewalks.

The contractor will provide written notification of work activities to all residents and businesses within the project area. Daytime operations are limited to the hours of 8 a.m. to 6 p.m. Evening work, mostly on main thoroughfares, will take place between the hours of 8 p.m. and 5 a.m.

The project is being funded through the City’s Sewer Enterprise Funds. No additional tax revenue will be required to complete the project.

Phase 1

The first phase of the project includes streets to the north of Todos Santos Plaza including sections of Concord Avenue, Bonifacio Street, Almond Avenue, Bacon Street, East Street and some of the adjoining cross streets. The project will begin in November. The contractor has 160 working days to complete Phase 1.

Phase 2

Phase 2 is scheduled to begin in the summer of 2013. This project will address the sewer lines near Todos Santos Plaza, including sections of Colfax Street, Grant Street and Galindo Street.

Phase 3

In the summer of 2015, work will begin on the final phase of the project and will include sections of Salvio Street, Sutter Street, Broadway Street, Concord Boulevard and some cross streets.
