Water Use Changes with Tempe's Shift from Agriculture to Urban Development

The ChandlerTalks meeting held on May 12, 2025, focused on the General Plan Update for the City of Chandler, Arizona, with a significant discussion on the relationship between land use and water consumption.

A key point raised during the meeting was the common misconception that population growth directly leads to increased water use. Experts clarified that water consumption is more closely tied to land use patterns rather than just population numbers. For instance, transitioning agricultural land, such as cotton fields, to urban developments can actually result in lower water usage.

An example shared highlighted that growing cotton requires between three to six acre-feet of water per acre, while developing residential subdivisions typically uses only about 1.2 acre-feet per acre. This indicates that urbanization can lead to water savings, although exceptions exist for industries with high water demands, such as data centers and food processing facilities.

The discussion emphasized the importance of considering how land is utilized when planning for future growth. As the city updates its general plan, officials are encouraged to focus on housing, quality of life, and industries that foster career opportunities while being mindful of water use implications.

In conclusion, the meeting underscored the critical connection between land use and water management, suggesting that thoughtful urban planning can contribute to more sustainable water practices in Chandler.
