City could store three Lake Austins’ worth of water underground by 2040

Austin gets all of its water from the Highland Lakes, but that might not always be the case. The city recently took a first step towards storing massive amounts of water underground. If the plan works, it could help Austin survive as climate change threatens traditional water supplies.

Aquifer storage and recovery is touted as a good way to take advantage of weather extremes, capturing excess water in times of flooding to then use in times of drought.
