Deep Tunnel 50th Birthday and Virtual Tour
October 26, 10 a.m.
Join us at 10 a.m. on Wednesday, Oct. 26 for a live virtual tour to celebrate the 50th birthday of the Tunnel and Reservoir Plan (TARP), aka the Deep Tunnel, the vast project designed to protect our rivers and Lake Michigan from sewer overflows and provide an outlet for floodwaters to reduce street and basement backup flooding.
Descend hundreds of feet underground to see tunnels being excavated. Watch as thousands of tons of rock are blasted out during reservoir construction. See billions of gallons of combined sewage captured and pumped to treatment plants to be cleaned. Join our biologists to survey the effects of the project on water quality and fish population.
Special guests will share their first-hand knowledge of planning, building, and operating this one-of-a-kind system. The tour will feature never before seen views of the project, drone video, archival film, and 425-million-year-old fossils.
