Contents Notes
A bold concept in the design of urban drainage systems was developed to help solve combined sewer overflow problems. A deep tunnel in bed rock 61 to 76 m (200 to 250 ft) below the surface was designed and constructed for the Lawrence Avenue drainage basin in Chicago. The tunnel also serves as a reservoir for capturing small storms and trapping a significant portion of the first flush of pollutants from large storms. The entrapped, combined sewage is pumped to the treatment plant at the end of each storm. Flows and pollutants to the Chicago River and treatment plant from selected outfalls in the Lawrence Avenue drainage basin were monitored, and the U.S. Environmental Protection Agency Storm Water Management Model was calibrated with the measured data. Performance of the tunnel system in capturing flows and pollution was evaluated with the help of the calibrated model. Groundwater monitoring was conducted for preproject and postproject conditions, and results were analyzed to assess the influence (if any) of the deep tunnel system on the underground aquifer. The results of the study show that the use of deep rock tunnels in conjunction with a pumping station is a very effective means of reducing the spillage of combined sewer flows and pollutants to the waterway. Use of modern tunnel-boring machines has improved the economics of this design and installation is also less disruptive to traffic and to the general public.
