Above is a rendering of the proposed project at Highway 179 and West Mallard Drive in Sedona.

East Sedona Water Storage Facility Project

Arizona Water Company (“Arizona Water”) has started constructing its East Sedona Water Storage Facility Project in summer (2023). Arizona Water is dedicated to providing and maintaining quality service to all of our Sedona-area customers and is constructing this underground water storage facility to meet drinking water and fire flow demands in the surrounding community.
The project will include the following facilities:

  • Underground 1.5 million gallon water storage tank
  • Booster Pump Station with a firm capacity of 3,000 gallons per minute.

The storage tank will be built completely underground and not be visible to the surrounding community. The booster pump station will be constructed on top of the underground storage tank and will be closed off by an architectural style enclosure that closely resembles surrounding homes in the area.

This is an important project that has taken years of planning, design which includes the selection of the site, a nearly one-acre lot located at the intersection of West Mallard Drive and Highway 179.

Arizona Water looks to working with our neighbors and other community stakeholders throughout the construction process. This web page is the place to find the latest documents and updates regarding this project, so please check it often.

07.17.2023 Letter to neighbors which was mailed out

Dear Neighbor:
Arizona Water Company ("Arizona Water") will soon begin construction on an underground 1.5 million gallon water storage tank and booster pump station, located at the intersection of Arizona State Highway 179 and West Mallard Road. Once complete, the new underground storage tank and booster pump station will provide the necessary storage to meet drinking water and fire flow demands in the southern end of the Sedona water system.

As your neighbor, Arizona Water wants to keep you informed about the status of the project. To that end, we will send regular updates to our neighbors by U.S. Mail and place updates and relevant information about the project on our website, www.azwater.com.

Various site preparation activities will commence in August 2023, beginning with a temporary entrance to the property at the intersection of Arizona State Highway 179 and West Mallard Road to minimize construction equipment and traffic in the neighborhood.

Excavation of the site by blasting is scheduled to commence at the end of summer 2023 and completed by the end of 2023.

Construction of the tank itself is expected to take approximately 18 months and will commence upon completion of site excavation.

Our goal is to complete this project safely and on-time while minimizing the overall impact to our neighbors during construction.

If you have any questions, please call our local Sedona office at 928-282-7092. We look forward to hearing your questions.

Very truly yours,
John Snickers
Division Manager
