PHOENIX (April 11, 2018) ─ Groundwater recharge is a process where water moves downward from the surface to an underground holding place called an aquifer. In the last 22 years, several public agencies have approached the Flood Control District of Maricopa County (FCD or District) for groundwater recharge on District land. Faced with high costs to accommodate both flood facilities plus an annual lease amounting to 10% of property value, the entities decided to pass on the opportunity or look elsewhere. The District Board of Directors has passed a resolution allowing FCD lands to be used for groundwater recharge at no cost to other public agencies. This provision is contingent on Board approval for use of District facilities and the project must not interfere with or degrade FCD structures or incur additional cost to the District.

"We live in a desert environment prone to drought conditions," said Board Chairman Steve Chucri, District 2. "This makes water a precious, vital resource for Arizona families. The Flood Control District is helping to ensure groundwater recharge projects aren’t hindered due to unnecessary cost."
According to the Arizona Municipal Water Users Association, communities prepare for drought in three important ways. They store surplus water for later use, similarly to how reservoirs do behind dams. Aquifers can also store treated wastewater for times of surface water shortage. Aquifers also contain significant amounts of natural groundwater that acts as a buffer against shortages in surface water supplies from the Central Arizona Project or Salt River. While Arizona aquifers are generally in good health, water management laws and policies are still vital to protecting them and reducing subsidence problems.
"Although April is Arizona Water Month and given how important water is to Arizona, it is important that we focus on preserving this resource every day," said Bill Wiley, FCD Chief Engineer and General Manager. "The Flood Control District is committed to groundwater recharge and replenishing aquifers to protect against shortages in Arizona water supplies."
