Project Type: Drinking Water
The Zone 3D and 4A Improvements Program will install both boosters and water mains to interconnect its north and south systems. This will enable the City to move water from wells throughout the southern part of the City to areas at higher elevation that are presently served predominantly with Colorado River water. By connecting the northern part of Phoenix, presently supplied with Colorado River water delivered through the Central Arizona Project, with the southern part served with water from the Salt River Project, the City will be able to ensure reliable service to the northern population if the availability of Colorado River water is reduced.You may need a PDF reader to view some of the files on this page.
