DRAINAGE PROBLEMS OF THE CHICAGOLAND AREA

THE METROPOLITAN CHICAGO AREA IS FACED WITH A SERIOUS COMBINED SEWER OVERFLOW, DRAINAGE AND POLLUTION PROBLEM, WHICH ACCOUNTS FOR ALMOST 40 PERCENT OF THE POLLUTIONAL LOAD ON ITS WATERWAY SYSTEM. IN AN ATTEMPT TO FIND THE MOST ECONOMICAL SOLUTION TO THE PROBLEM, A STUDY WAS INITIATED WHICH INCLUDED EXTENSIVE INVESTIGATIONS OF THE GEOLOGICAL STRATA, THE QUANTITY AND QUALITY OF STORM RUNOFF TO BE DEALT WITH, AND THE VARIOUS METHODS OF STORAGE AND TREATMENT AVAILABLE. ONE OF THE SOLUTIONS CONSIDERED WAS THE CONCEPT INVOLVING A SERIES OF TUNNELS, ROCK TUNNELS, SHAFTS AND STORAGE AREAS, WHICH WILL COLLECT, RETAIN AND SUBSEQUENTLY TREAT THAT PORTION OF THE COMBINED SEWER OVERFLOW WHICH CAN BE HANDLED IN THE MOST COST-EFFECTIVE AND ECONOMICAL WAY AND IN COMPLIANCE WITH FEDERAL AND STATE REQUIREMENTS. THE SYSTEM OF TUNNELS WILL EXTEND FOR 125 MILES. A STUDY TEAM HAS CONCLUDED THAT TUNNELING IS ONE OF THE MOST COST- EFFECTIVE ALTERNATIVES AVAILABLE. THE HISTORICAL CONTEXT OF THE DRAINAGE PROBLEM IS ELABORATED. FINANCIAL AND RESOURCE PROBLEMS ARE ALSO DISCUSSED.
