The Alvarado-Niles Pipeline Seismic Improvement Project is part of the District’s $10 million per year Main Renewal and Seismic Upgrade Program (MRSUP). This vital project will improve the seismic reliability of the water distribution systems in the northern portion of the Alameda County Water District’s service area. The project will include the installation of over 3.5 miles of 14-inch and 16-inch steel pipe along Smith Street and Alvarado Niles Road, between Union City Boulevard and Decoto Road. This pipeline will be designed and installed to sustain a major seismic event along the Hayward Fault, and provide a critical water lifeline to our customers in the District’s northern service area. Construction of the first phase was completed in July, 2021; construction of the second phase is planned for early 2024.
Phase 2 - Smith Street at Union Pacific Railroad tracks, Alvarado Niles Road, between Santa Maria Drive and Almaden Boulevard, and between Central Avenue and Decoto Road. Map (PDF)
