Document Description: The proposed program would rehabilitate the Prestressed Concrete Cylinder Pipe (PCCP) portions of five subsurface water distribution pipelines which are nearing the end of their service life. The program would reduce the risk of unplanned outages, extend the service life of the pipelines, and improve operational and emergency flexibility. Rehabilitation methods include steel cylinder relining with collapsed pipe, steel pipe slip-lining with non-collapsed pipe, and replacement or new pipe construction. Maintenance and replacement of worn or outdates appurtenant structures (e.g. above-ground air release valves, vacuum valves, manholes, and buried vault structures) would also be completed as part of this program. Individual projects will occur in Metropolitan owned rights-of-way, public roads and open space; however, construction may result in temporary impacts to general commercial, residential, business, recreation and open space areas. Work may include acquisition of additional temporary right of way to facilitate construction.
