Thursday marked the completion of a 14-year project to clean up our rivers. The DigIndy Tunnel System is one of the largest civil infrastructure projects in the history of Indianapolis. The tunnel is more than 250 feet below the Earth's surface and is designed to capture and treat sewer overflow to keep it from going into local waterways. https://www.wthr.com/article/news/local/digindy-tunnel-system-wastewater-rain-indianapolis-rivers-environment/531-c43472a7-bb5f-4355-b31a-c5c64ed317a8
