Town Council Meeting
Experts walked the council through Colorado River cuts, groundwater law, and local well data. Sahuarita's aquifer lost about 26.5 feet over 20 years while the Tucson AMA overall gained — a gap partly tied to recharge happening up north. The Hudbay mine's 6,000 acre-foot permit with 105% recharge commitments and possible data center demand were key concerns.

Town Council Meeting
With all domestic water provided by private companies, residents pressed the council on falling aquifer levels, cutbacks in CAP water, and how large industrial users would be evaluated. A water forum with all providers and state officials is set for late September.

Global Water's annual report turned into a deep dive on the aquifer, assured water supply designations, and what a giant copper mine might mean for future supply — and whether costs shift from tax bills to water bills.
Town Council Meeting
A resident warned that Project Renews can't mathematically replace the water the community needs, citing Lake Mead declines and shrinking CAP allocations, and asked what the town's Plan B is.
