The City of Corona has begun a wastewater infrastructure work on California Avenue. Construction will take place from May 2018 through early 2019 and will require both day and night work.

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).

Latest Construction Updates:

California Avenue Sewer Pipeline Project 12.7.18

Daytime construction along California Avenue north of Old Temescal Road to install the new gravity sewer line

will begin on Monday, December 10 and continue through Friday, December 21. Work in this area will recommence after the winter holiday on Monday, January 7. The sewer construction work is being switched to daytime hours to improve safety for the public and the construction workers where conflicts with existing utilities and deep trenches make construction challenging.

A short section of California Avenue north of Old Temescal Road will be closed during this time with a detour provided on Pico Street, Compton Avenue, and Old Temescal Road. Access to all private driveways and the post office will remain open during construction. Delays may occur along California Avenue and nearby streets due to this construction.




Work on the California Avenue Sewer Pipeline Project continues to move forward. The following schedule is planned for work on California Avenue through November 2018. There are no construction activities planned for the Thanksgiving Holiday or near retail businesses on Black Friday.

Mid-November: Final street paving and striping will begin about the 3rd week of November for the general area from Ontario Avenue to Foothill Parkway.  We anticipate being able to pave near the school during the week school is on vacation provided there are no construction delays or inclement weather. Paving is expected to require a number of days with striping to follow approximately one week later.  Expect traffic detours and delays during paving and striping.

There will be no additional planned construction in these areas once final paving and striping have been completed. 

Night work on California Avenue will commence starting at Pico Street moving south during the second part of November.




  • Jack and bore operation under Ontario Avenue is now complete.
  • The next jack and bore operation will begin today, June 26th at the intersection of Old Temescal Road and take approximately three weeks to complete. 
  • The contractor anticipates starting construction on or about July 9 for installation of pipe in California Avenue from Taber Street to Foothill Parkway.  Sewer line construction work between Ontario Avenue and Taber Drive will resume after construction has been completed to Foothill Parkway.
  • A second jack and bore operation is also scheduled to start on July 5 at the intersection of Chase Drive and take approximately one month to complete. 


What Does the Work Entail?

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.

Why Is This Project Needed?

This project will support the planned decommissioning of the City’s Water Reclamation Facility #3 (WRF3) and provide sewer infrastructure necessary for the Arantine Hills Development, located west of I-15 and south of Cajalco Road/Eagle Glen Parkway.

The WRF3 is being decommissioned to reduce the long-term costs of water reclamation operations. The sewer flows will be re-routed to the City’s Water Reclamation Facility #1, located at Railroad Street near Klug Circle, and to the Western Riverside County Regional Wastewater Authority treatment plant in Eastvale.


What You Can Expect

Please expect lane closures, detours, delays and parking restrictions near the work sites during construction activity. California Avenue will be closed to through traffic during nighttime construction. Permanent traffic control devices including K-rails will remain at key locations while other temporary traffic control will be removed daily prior to morning traffic to minimize congestion. Construction equipment may be parked along the project alignment during non-working hours with traffic control devices provided to guide traffic around the work area. Mail, trash and delivery services are expected to continue unhindered. Local and emergency access will be maintained at all times. Lighting will be required for nighttime work and noise is to be expected from construction activities.
