Site work for a water / sewer project in Corona, California. Conceptual plans call for site work for a water / sewer project.

The Department of Water and Power (DWP) maintains nearly 650 miles of water main throughout the city. On Friday, April 23, 2021, DWP staff responded to a water main break on Liberty Avenue and Jolora Avenue. The water main is a 10" steel pipe constructed in 1958 with 63 years of service that runs along the south side of Liberty Avenue, adjacent to the public right-of-way. Cement mortar lines steel pipes have been estimated to have a typical useful life of 80-100 years, but the actual useful life can vary greatly depending on soil conditions and the quality of construction. Leaks experienced on a steel waterline are often precursors to additional leaks because the leaks are commonly a result of corrosion.When the water main broke, water ran down both sides of the line to the new development currently under construction, through the business at 19930 Rosita Street and flooded the house at 19933 Temescal Canyon Road. DWP immediately contacted a contractor, Builders Choice, to initiate the water damage containment process. There have also been several other leaks on this water main over the last 10 years. The location of this water line has become a concern due to the new commercial development that is being builtsouth of and lower in elevation than the water main. Considerable damages to the development if future leaks occur and it is not replaced. To proactively prevent further flooding ncidences, the DWP Infrastructure division along with Public Works and Engineering staff have agreed that this waterline is a high priority for replacement. This project is in included in the City of Corona 2022-2026 Capital Improvement Plan (CIP).
