The Tunnel and Reservoir Plan (TARP), commonly referred to as the Deep Tunnel Project, has a rich history that dates back to the late 1970s. The project was initiated in response to the growing concerns over flooding and water pollution in the Chicago metropolitan area. As urban development surged, the existing sewer systems became increasingly inadequate, leading to frequent overflows and environmental degradation.
In 1972, the U.S. Environmental Protection Agency (EPA) mandated that cities across the nation improve their wastewater management systems, prompting Chicago to take decisive action. The TARP was conceived as a comprehensive solution to these pressing issues, aiming to mitigate flooding and enhance water quality.
By the early 1980s, the project had gained momentum, with the Metropolitan Water Reclamation District of Greater Chicago (MWRD) taking the lead in its implementation. The first phase of construction began in 1985, marking a significant milestone in the project’s timeline.
Over the years, TARP has evolved into one of the largest and most ambitious civil engineering projects in the United States, with a network of deep tunnels and reservoirs designed to capture and store excess stormwater and sewage. This historical backdrop sets the stage for understanding the project’s significance in addressing urban water management challenges.
