Project Details

The City's Water Resources Department regularly inspects water deliver infrastructure to monitor its condition and facilitate prioritization of maintenance and improvement projects. Recent surveys of the condition of the 42-inch diameter pre-stressed concrete cylinder pipe (PCCP) waterline for the Pasadena Reservoir (which fills the reservoir from the Val Vista Treatment Plant) revealed evidence of deterioration in the segment that passes through the Park Centre Casitas development. Because the existing pipe line passes through a developed area with limited clearance from existing homes, the City determined that removal and replacement of the pipe using open excavation methods is not feasible. It was determined to rehabilitate this line by installing a new high density polyethylene (HDPE) pipe, as a liner, inside the existing deteriorated pipe. The liner pipe will support imposed loads should the existing pipe further deteriorate over time.
