The project just completed work on one of the major reservoirs used by the system. The Thornton Reservoir is a limestone quarry that can hold 8 billion US gallons (30,280,000 m^2) Here's a video of the reservoir taking in 400 million gallons after a heavy rainfall last week: http://www.dnainfo.com/chicago/20151203/south-chicago/watch-400-million-gallons-of-stormwater-rush-into-chicagos-grand-canyon http://www.dnainfo.com/chicago/20151203/south-chicago/watch-...
