This $18 million project provided relief for increased sanitary sewer flows from planned development in the Railyards Project area and the River District Specific Plan area. The project constructed approximately 5,700 feet of 42-inch diameter and 410 feet of 48-inch diameter (CSS) pipelines within 3rd Street from I Street to U Street, and within T Street from 3rd Street to 5th Street. The pipelines connect to an existing 84-inch diameter CSS at 3rd Street and U Street and to a 60-inch diameter CSS at 5th Street and T Street. Portions of the project were within State right of way and were constructed under a Caltrans Encroachment Permit. UNICO provided construction management and inspection services that included project management, resident engineering services, and public outreach, as well as civil inspection, and office engineering.
