demand calculator; rules; conservation code

SB 1115 requires Arizona's water department to update its project demand calculator every five years through formal rulemaking. The rules must clearly list all inputs used in the calculator and incorporate the most current conservation codes. This bill directly affects the department's water planning processes but does not change water usage rules for residents or businesses. The bill failed to pass in the Arizona legislature on April 28, 2025, so these requirements were never implemented.
