Box Springs Feeder Repairs - Phase I Design and Construction
Document Type
NOE - Notice of Exemption
Document Description
The Metropolitan recently conducted electromagnetic inspections, which revealed sixteen 20-foot long pipe sections with anomalous readings as to the integrity of the prestressing wires. The extend of the damage, if any, at these locations could not be interpreted by the electromagnetic inspections due to the presence of internal steel bands within the pipeline. The internal bands were installed in 1989 in an attempt to repair "broken back" cracks, which were discovered during a routine inspection. The internal bands are no longer considered to be an effective means of permanent repair. In order to maintain reliable deliveries of source water to the Henry J. Mills Water Treatment Plant, all sixteen pipe sections should be removed and replaced with welded steel pipe sections. The recommended repairs will occur in phases in order to minimize the duration of pipeline shutdowns. Metropolitan is proposing the preparation of final design and construction of the Phase I repair of one segment of the pipeline located in the City of Riverside.
