Pasadena Water and Power is installing a new 8-inch water mainline in Fillmore Street between Fair Oaks Avenue and Raymond Avenue. The pipeline will reinforce the reliability of water service to the area.

Construction will occur overnight from 10 p.m. to 6 a.m. beginning Monday, July 20 through Friday, July 24. The intersection of Fair Oaks Avenue and Fillmore Street will be closed, with detours routed through Bellefontaine Street and Raymond Avenue. Please see the map below for reference.

Drivers headed northbound on Fair Oaks are re-routed to make a left on Bellefontaine, then head north on Pasadena Avenue to reach California Boulevard. Drivers headed south on Fair Oaks are re-routed to make a left on California and a right on Raymond Avenue until they reach Glen Arm.

The water main replacement project will continue with daytime work from July 27 through mid-September. For questions or concerns, please contact Norman Lara at NLara@CityOfPasadena.net or (626) 744-7607. For complete details about the project, please visit Fillmore Water Main Replacement Project.
