groundwater replenishment; member lands; areas

This bill updates Arizona's groundwater replenishment rules to clarify how water districts must restore water levels in specific management areas. It requires districts to fill groundwater deficits within three years using stored water or non-groundwater sources, while exempting certain lands served by municipalities with assured water supplies from future replenishment duties. The law also establishes a process where cities can gradually take over the responsibility for replenishing water used by member lands over a ten-year period, eventually allowing them to stop reporting those specific usage details. Additionally, the bill clarifies how cities can use existing water credits when they assume these obligations, ensuring a structured transition of responsibility.
