The City of Phoenix Water Services Department is designing new infrastructure to continue providing a reliable water supply to 1.7 million customers.

The additional improvements will include 12 miles of new pipelines, four water booster pump stations, and pressure-reducing valve stations.

Project 1 will be located in the Phoenix Mountain Preserves and nearby neighborhoods and includes adding 48-inch and 66-inch pipelines at different segments.

Project 2 will run along 32nd Street from Shea Boulevard to Bell Road and will include adding a 66-inch pipeline. Construction will be completed in segments, as to not impact the entire area for the duration of the project. A median project was also previously planned for 32nd Street. Our Water Services Department will coordinate with our Street Transportation Department so that the pipeline is laid down before the medians are installed.

Project 3 will run along 35th Avenue from Thunderbird Road to Grovers Avenue and includes a 42-inch pipeline.

As part of the City’s preparation for resiliency in a hotter and drier future, the improvements will provide more flexibility to move Salt and Verde River water supplies to areas of the city that are currently entirely dependent on already over-allocated Colorado River water and are at risk for shortage.

Major upgrades to the water system are needed to allow water to be moved from the 24th Street and Deer Valley Water Treatment Plants to the Union Hill and Lake Pleasant Water Treatment Plants to supplement and provide reliable water deliveries.

Engineering design for the improvements began in early 2019, and construction is anticipated to occur from early 2020 through the end of 2022, although construction will happen in segments to minimize impact to the areas.

In the coming weeks, the Water Services Department will conduct outreach by sending a letter and placing a door hanger for residents, along with sharing information on social media, presenting to community groups, placing signage on streets and trailheads, etc.
