Chicago River Tunnel and Reservoir Plan (TARP)
The Chicago River Tunnel and Reservoir Plan (TARP) is a long-term project designed to reduce pollution and manage stormwater in Chicago. It involves constructing tunnels, reservoirs, and infrastructure to improve water quality by capturing and storing excess rainwater and sewage before they reach the river and Lake Michigan. This helps prevent flooding, reduces pollution, and enhances environmental health and public safety. TARP aims to modernize Chicago’s water management system, ensuring cleaner water, better flood control, and a more sustainable urban environment.
