![]() Thus preparations have been made to prevent ingress of water from all possible entry-points.Īn action timeline (disaster response plan) to deal with major flooding has also been instituted. Flood gates are also being installed in the entrances of tunnels, where train tracks on the surface descend underground. In addition to increasing the number of flood barriers, the entrances of stations are being rebuilt according to a completely flood-proof design, which can be sealed by closing water-tight doors. The conventional method could withstand the equivalent of a 2-meter depth of water pressure, but a new model, able to withstand pressures of 6 meters of water, has been installed in areas with high risk of flooding. Various flood control measures have been designed to keep them operating even during torrential rains and typhoons.Īs an example, consider the antiflooding mechanism for sealing the ventilation ducts drawing air from street level.

Since 1915, we have helped our clients improve the lives of people in over 100 countries through consulting, engineering, construction, operations and program management. Solar powered mixers will be deployed to keep reservoir surface layer aerated to minimize potential odor concerns.ĬHRISTOPHER CLARK | +1 91 P | +1 81 24-HOUR MEDIA HOTLINE | +1 86 About Black & Veatchīlack & Veatch is an employee-owned, global leader in building critical human infrastructure in Energy, Water, Telecommunications and Government Services.Grouting included drilling of over 150 miles of 4-inch diameter boreholes - some over 500 feet deep - followed by controlled injection of cement mixes into surrounding rock to seal off potential leaks in the reservoir.Mike Orth, Executive Managing Director for the Americas in Black & Veatch’s water business Editor’s Notes: We are proud to take part in helping the MWRD provide this vital water quality and flood protection to and for the people in and around Chicago.” “Other cities beset by chronic combined sewer overflows and flooding will look to this system as a model. McCook will ultimately provide 10 billion gallons of additional CSO and floodwater storage when commissioned in two stages in 20. “Because of TARP, combined sewer overflows have been drastically reduced, and the addition of Thornton will again lead to more water quality improvements upstream.”Īs part of the TARP initiative, Black & Veatch is also providing engineering and construction services for the McCook Reservoir. “In past years, that polluted, untreated water would enter our waterways or worse, our basements,” said MWRD President Mariyana Spyropoulos. Thornton Reservoir will provide an additional 7.9 billion gallons of storage for capture and treatment of CSOs and floodwaters. Additionally, moving that water to the reservoir will lessen the need to release sewage into Lake Michigan when rains overwhelm the area’s storm sewers. Previously, sewage-laced floodwater often inundated residential properties after heavy rains. TARP has significantly improved the quality of life for people living and working in the City and Cook County. The company contributed innovations in grouting practices in the design and construction of the reservoir. It will also protect against combined sewer overflows (CSOs) as well as overland and basement flooding.īlack & Veatch performed heavy infrastructure tunneling and engineering at Thornton. TARP is designed to protect Lake Michigan, the region’s primary source of drinking water. It is one of the largest water infrastructure projects in the world. Thornton Reservoir is a key component of the MWRD’s Tunnel and Reservoir Plan known as TARP. Army Corps of Engineers and other stakeholders joined the Metropolitan Water Reclamation District (MWRD) of Greater Chicago to cut the ribbon on Septemfor the nearly $450 million facility. Environmental Protection Agency, the U.S. Black & Veatch led planning, design and construction of significant components of the reservoir, which comes online by the end of the year. The Thornton Composite Reservoir, known to Chicago residents as the “Grand Canyon of the South Suburbs,” will benefit the city’s south side and 13 nearby suburbs through improved storm water protection and water quality.
