Aquifer Storage and Recovery Feast or famine. This is typical for many water utilities.
Water is plentiful during certain seasons, and drought conditions occur in other seasons.
Water demand is also cyclical, with the highest demand often occurring when the least amount of water is available. Utilities face a constant challenge of how to store water during times of plenty so that adequate resources are available when needed. ASR is also being applied in Australia, Israel, Netherlands, South Africa, and England. ASR usually involves the recharge of treated drinking water into an aquifer during wet periods or when the raw water quality is the best, with recovery during dry periods or when the raw water quality is poor. A bubble of high quality water is formed in the aquifer, which can be recovered and used with minimal treatment requirements.
