The Three Rivers Protection & Overflow Reduction Tunnel (3RPORT) is a combined sewer overflow (CSO) tunnel project located in Fort Wayne, Indiana.
It includes a deep rock tunnel, drop shafts and consolidation sewers to collect and convey CSO from eight locations along the St. Mary and Maumee Rivers. Once completed, the CSO tunnel system will reduce 90% of combined sewage overflows into the rivers, which occur during large rain storms.
