ABOUT THE TARP MCCOOK RESERVOIR PROJECT
Chicago’s Tunnel and Reservoir Plan (TARP) is a nearly $4.0 billion and over 30 years long program and
arguably the largest and longest combined sewer tunnel and reservoir system in the world. A massive tunnel construction is underway for connection of the McCook Reservoir to the existing TARP tunnel system. Once completed in two stages in 2017 and 2029, the reservoir will hold 38 billion‐liters (10 billion‐gallons) of combined sewer overflows (CSO) and flood waters from the city of Chicago and over 20 communities in Cook County, Illinois.
Field Trip attendees will be able to access the 33-ft dia McCook Tunnel and the 10-ft dia inflow/outflow tunnel daylighting into the reservoir. The McCook Main Tunnel system consists of a 10 m (33 ft) finished diameter and 490 m (1,600 ft) long hard rock tunnel constructed from a 27.5 m (90 ft) diameter and 92 m (300 ft) deep main gate and tunnel construction access shaft.
