An effective technology to control urban flooding and combined sewer overflow (CSO) is inlet control. The inlet control technology is usually combined with other technologies such as storage and relief sewers to become a control plan. This combination is developed in such a way that use of the existing system is maximized and construction of new facilities is minimized, using site-specific conditions of the sewer systems including topography, time of concentration, conveyance capacities, land development, available depth and public preference. Such site-specific combinations are a key to the successful development of an inlet control alternative (ICA) which is highly implementable and cost effective. Two real world projects are illustrated and compared for discussion on the adaptability and cost-effectiveness of ICA. In summary, general guidelines for development of ICA are developed.
