"We are many travelers in a land that has limited water resources, and the distance and direction to the next oasis are not well known. However, the camel knows the way and will guide us. By storing water when and where it is available, the camel is an appropriate symbol for a world in which the incessant increase in demand for water is challenging our ability to meet this demand."
... for many communities and nations which are increasingly challenged by population growth, declining groundwater levels, contaminated aquifers, concerns regarding water supply security, declining streamflows, increasing saltwater intrusion, ground subsidence, global climate change, and unacceptable impacts upon aquatic and terrestrial ecosystems.
... for water resources management and environmental protection, enabling storage deep underground when water is available, for recovery when needed to meet urban, agricultural, ecosystem, industrial, recreational, emergency and other water uses.

The same wells are used for both recharge and recovery. Water is stored in suitable aquifers, or water-bearing formations, forming large subsurface reservoirs that are safe from losses due to evaporation, transpiration, seepage or contamination.
