DigIndy Tunnel Prevents 74 Million Gallons of Sewage from Entering Area Waterways

 Benefits of First Tunnel Segment Especially Noticeable During Last Week’s Heavy Rain

INDIANAPOLIS – Since its opening on December 29, 2017, the first 10 miles of the DigIndy Tunnel System has prevented more than 74 million gallons of sewage from entering the White River and Eagle Creek. Last week alone when the area experienced exceptionally heavy rain, the tunnel prevented nearly 55 million gallons of sewage from entering those waterways.

The Deep Rock Tunnel Connector and the Eagle Creek Deep Tunnel, which comprise the open segment, will work in tandem with the previously expanded Southport Advanced Wastewater Treatment Plant to prevent more than 1 billion gallons of sewage from entering White River and Eagle Creek annually across the southern half of Marion County.

Citizens Vice President of Water Operations Jeff Willman said, “We couldn’t be more pleased with how the newly opened portion of the DigIndy Tunnel System performed over the past week, capturing nearly 55 million gallons of sewage that previously would have entered our waterways. However, it’s not just during abnormally heavy rain events that this segment of the system will make a great impact. Even during rain events of as little as one quarter of an inch, which are much more common, thousands of gallons of sewage will be prevented from entering the White River and Eagle Creek.”

When the full 28-mile DigIndy Tunnel system is complete in 2025, about 99 percent of sewage will be prevented from entering all streams and the White River in Marion County, thus enhancing recreational opportunities while helping drive neighborhood revitalization and economic development across the city. DigIndy will also keep Citizens and the City of Indianapolis in compliance with a federal Consent Decree with the U.S. Environmental Protection Agency, the U.S. Department of Justice and the Indiana Department of Environmental Management.
