Water Resource Usage and Aquifer Sustainability
Summary
Water use is running 2-3% below last year, and Countryside groundwater pumping has collapsed from 200 to 38 acre-feet thanks to the upgraded CAP wheeling station. But commissioners noted the aquifer is still drawn down by neighbors like SaddleBrooke, Catalina and the Oro Valley Country Club, and safe-yield remains a work in progress.

Impact analysis
Reducing groundwater reliance is driving major capital spending on recharge and delivery infrastructure.
Everyone on the aquifer benefits as the utility pumps less groundwater and imports more renewable supply.
Neighboring upstream pumpers and the country club's in-town groundwater irrigation continue to stress the shared aquifer.
