| What is the CAGRD? The Central Arizona Groundwater Replenishment District (CAGRD) was established in 1993 by the state legislature to serve as a groundwater replenishment entity for its members. It provides a method for property owners and water providers to demonstrate a 100-year assured water supply under Arizona law by agreeing to have the CAGRD recharge amounts of groundwater that are over the usage limits established by the assured water supply rules. |
