The Central Arizona Groundwater Replenishment District (CAGRD) was created in the mid-1990s to help water providers and landowners comply with Arizona’s groundwater laws. CAGRD plays an important role in Arizona’s groundwater management by replenishing groundwater pumped by its members. CAGRD is not a separate entity, but rather a special function of Central Arizona Project.


CAGRD is a special function of Central Arizona Project, replenishing water to foster and enhance responsible groundwater management.
