Why Inject Drinking Water Underground?

An earlier post had to do with a comment period for proposed changes in a permit to inject drinking water into an underground aquifer.  A visitor to this blog asked why would anybody want to inject drinking water into an underground aquifer in an area with abundant drinking water supplies?

I found this at the web site of the Joint Powers Water Board of Albertville - Hanover - St. Michael, MN:

Current & Upcoming Construction Projects

The Joint Powers Water Utility is a Pioneer in Minnesota

The Joint Powers Water Board recently constructed what is referred to as aquifer storage and recovery (ASR), and it is the first such system in Minnesota. The primary purpose for us is to provide adequate storage capacity of treated water without the need to build additional treatment plants and water towers. We will take already treated/filtered water from the distribution system during the slower winter months, pump it into the ground to be pumped back out during the summer peak water demands. This results in a tremendous cost savings to you, the customer.
