Distribution report: Country Club Drive 12-inch main break isolated and repaired; staff detail lessons for CIP prioritization
Summary
Distribution staff described a 12-inch cast-iron main failure on Country Club Drive that affected about 80 homes; crews isolated water within 30–40 minutes and completed repairs and repaving work within roughly 28 hours, and staff said the event will inform CIP and monitoring priorities.
Del Wirtz, reporting on the FY25–26 water distribution update, described recent leak history and detailed two large main breaks that occurred during the quarter. The most significant was a 12-inch cast iron main that failed April 27; crews isolated flow within 30–40 minutes, repaired the pipe and restored water service after approximately 13 hours from start of repair through recharging the line, and completed full restoration including temporary pavement within about 28 hours of the event.
Wirtz said the failed pipe dated from 1967 and showed exterior corrosion and a circumferential crack. He described repair techniques and temporary patching and said the city will monitor the patched pavement and return for permanent grinding and cap in several months. Commissioners asked whether any West Hollywood–style catastrophic risk exists in Glendora; staff said the water master plan and enhanced monitoring (GIS, leak prediction, added pressure monitoring) guide CIP prioritization and that the city participates in an insurance pool (Prism) that could help cover large incidents. The commission voted 5–0 to receive and file the distribution update.
