Main Renewal and Seismic Improvement Program (MRSIP)

As part of its commitment to delivering a reliable drinking water supply to homes and businesses in Fremont, Newark, and Union City, the District implemented a District-wide Main Renewal and Seismic Improvement Program (MRSIP). MRSIP projects include upgrading and seismically retrofitting water delivery pipelines and facilities. Intensive infrastructure upgrades will help improve water supply reliability for District customers in the event of a major earthquake and will reduce service interruptions due to aging pipelines.
