The Main Renewal and Seismic Upgrade Program is part of the Alameda County Water District’s (District) commitment to delivering reliable drinking water supplies to more than 356,000 people living and working in Fremont, Newark and Union City. The Main Renewal and Seismic Upgrade Program will help improve water supply reliability for ACWD customers in the event of a major earthquake and will reduce service interruptions due to aging pipelines. Generally, pipelines have a lifespan of about 75 years, but the risk of a pipeline’s failure increases in proportion with its age. With twenty percent of the District’s pipelines installed before 1960, and the oldest pipelines placed underground in the 1940s, this project represents a major infrastructure improvement for more than 84,000 customers who depend upon reliable water supplies. Proactive pipeline upgrades protect the District and its customers from expensive fixes caused by leaks in the system.
