Prescott Valley officials have authorized building a concrete 3 million-gallon water storage tank on Glassford Hill. MGC Corporation is the builder.
That decision was prompted by a growing population and improving water levels.
The $4.2 million cost for the tank is being split between the Town of Prescott Valley and Jasper Subdivision developer AZ Eco-Development. The development company will pay the cost for slightly more than half — $1.7 million — of the 3 million-gallon capacity. The Town will pay the balance using fees collected from new home construction.
When complete, the new tank will increase the Town’s cumulative water storage capacity to 18 million gallons.
The tank is near an existing 1 million-gallon tank adjacent to the Glassford Hill Summit Trail at the west edge of town. The hiking trail will remain open except during periods of heavy construction activity.
Additional storage capacity gives the Town more flexibility in meeting peak water demands and in providing additional water resources in event of emergencies.
Even during a slowing economy, residential construction continues to be stable as the Town’s population increases. In 2018, the population was approaching 46,000. Prescott Valley is the largest incorporated community in Yavapai County.
Town Manager Larry Tarkowski said the aquifer over which the Town is built has been rebounding in water levels. Since summer 2018, the Town has not pumped from the Central Well Field near the center of town. Instead, the Town pumped from a well field north of Highway 89A, said Town Utilities Director Neil Wadsworth.
He said the Town will continue pumping from other locations to allow wells to rest to prevent major declines at any one well site. Part of the aquifer runs from Dewey west to Williamson Valley and then north to Chino Valley.
The Town must comply with managing its water resources by following state regulations and the management plan for the Prescott Active Management Area. That plan adheres to Arizona Department of Water Resources requirements.
