Olive Ave waterline project

Skanska USA Building and Granite Construction will be managing the installation of a waterline from N Dysart Rd and W Olive Ave in El Mirage eastward to the Parshall Flume Station, located at W Olive Ave and N 99th Ave. This project will be constructed in two phases.

Phase I will be the horizontal directional drilling to occur under the Agua Fria River. Phase I work is expected to begin April 2026 and consists of drilling boreholes for the waterline under the Agua Fria River and pulling casing and carrier pipe through the boreholes. This work will occur south of W Olive Ave. The Agua Fria crossing is planned to be completed near the end of 2026.

Phase II is the waterline work south of W Olive Ave beginning in April 2026. The work will start at the east and west connection points south of W Olive Ave (El Mirage to 114th Lane) and meet in the middle at the Agua Fria Bridge. Completion of the waterline work is expected to continue through December 2026.

Work is scheduled for Monday through Friday between 6 AM and 4 PM, with occasional work on Saturdays and Sundays if the severe summer heat and monsoon weather creates project delays.
