The metro Atlanta area “has made incremental progress in reducing water use” since a 2011 report that states the region could save as much as 160 million gallons of water per day through certain conservation measures. That’s according to Atlanta-based advocacy group Chattahoochee Riverkeeper, which has released a 40-page update to its 2011 report, “Filling the Water Gap: Conservation Successes and Missed Opportunities in Metro Atlanta.” “However, we can and should do more,” states the update, which was released earlier this month.
