Chicago leaders on Tuesday unveiled new equipment that they hope can prevent flooding on the city's West Side.

Chicago is quietly tucking massive stormwater tanks under West Side streets, betting that a pair of buried concrete boxes can keep the next big downpour from ending up in residents' basements.

The City of Chicago Department of Water Management and the Metropolitan Water District of Greater Chicago Tuesday are set to unveil two giant underground stormwater storage units meant to help reduce flooding in parts of the city.

Construction is underway on a new underground stormwater storage facility in Chicago's Austin neighborhood. It's part of a broader effort to increase stormwater storage capacity on the city's West Side. While the project will not be completed until the fall, officials say its long-term significance is critical.
