The Small Diameter Pipeline Renewal Program is part of the larger District’s Water Main Renewal Program to replace and upgrade critical, aging water infrastructure and improve water service reliability. The smaller and less complex pipeline renewal projects support the large diameter transmission main renewal projects currently in progress. With planned construction on an as-needed basis, the Small Diameter Pipeline Renewal Program will provide more consistent year-to-year progress and expenditures within the District’s Main Renewal Program.

The Small Diameter Pipeline Renewal Program includes nine project sites. Each site is comprised of multiple water mains and was chosen based on material type, age and maintenance history. The water mains are generally older pipelines located in residential areas throughout Fremont, Newark, and Union City.


The Main Renewal – Souza Avenue and Concord Street Project is the first project to be awarded for construction.  Design of the remaining project sites is currently in progress.

The Lindsay Tract Roadway and Drainage Improvements Project is being led by the City of Newark, and ACWD is partnering to replace aging water mains for cost efficiency and to minimize impacts on customers. The water main replacement will be entirely funded through ACWD’s Capital Improvements Program budget.

Multiple project sites throughout Fremont, Newark, and Union City.
