CSO SOLUTIONS

It is estimated that 1200 cities have nearly 20,000 combined sewer overflow points in areas serving more than 43 million people. Their impact on waterways has become a national problem, yet only 328 cities have abatement plans. The 1972 Clean Water Act which addressed this problem is discussed, as well as the costs of solving the problem. The 1989 National Control Strategy for Combined Sewer Overflows requires states to create a statewide strategy for compliance with technology and water quality-based regulations. The funding for CSO control programs is discussed, as well as specific CSO control programs. These include Chicago's $4 billion Tunnel and Reservoir Plan; New York city programs; and the Washington, D.C. program. The technologies used in the programs are discussed and include 'swirl' technology, and improvements of it.
