About the California Avenue Sewer Pipeline Project

The California Avenue Sewer Pipeline Project will provide additional flow capacity to carry sewage from new development and the planned decommissioning of the City's Water Reclamation Facility #3 (WRF3).

The project will construct approximately 8,600 linear feet of new sewer pipeline and associated manholes along California Avenue. The majority of the sewer will be installed using traditional open cut methods. Sewer construction at major street crossings will be constructed using trenchless technology, such as bore and jack methods which installs the pipe between two installation pits. Trenchless construction will minimize traffic disruption at high volume intersections at Old Temescal Road, Ontario Avenue and Chase Drive.

Please be advised that traffic delays are to be expected. Plan accordingly by taking alternate routes and allowing more travel time for known traffic delays. The City of Corona appreciates your patience and support while we make these important infrastructure improvements.  We apologize for the temporary inconvenience.
