Description:
The options for pollution abatement in WWF can be implemented at the source by land management and pollution prevention techniques, in the collection system, offline by storage, or in a treatment plant. An integrated system that combines prevention, control, and treatment has often been found more effective than the use of treatment alone. Many conventional treatment processes cannot efficiently handle the high-volume short-duration flows associated with wet weather. In addition, more information is needed on the use of nonstructural source controls, such as: public education, substitution of materials that are less toxic, recycling, prevention of illicit discharges, and catchbasin cleaning. Many municipalities are focusing on these controls over the more costly structural approaches; however, nonstructural controls require a higher level of commitment to be effective on a continual basis. Existing technologies to reduce and/or eliminate pollution from CSOs can be grouped into the following main categories: 1) Source control incorporates land management and pollution prevention techniques to reduce the quantity and pollution potential of SW before it enters the sewerage system; 2) Collection system control ensures that O&M of CSSs is as efficient as possible and that maximum advantage is taken of opportunities to increase seer- flow carrying capacities and use the number and volume of overflows; 3) Storage utilizes inline regulators and controls to store flow in the sewerage system and/or in earthen or concrete basins to retain WWF until it can be treated at the WWTP; 4) Treatment and Disinfection emphasizes high-rate processes. This chapter presents a summary of WWF control and storage technologies that have been developed by the US EPA, Office of Research and Development over the past forty years. CSO treatment and disinfection technologies, are discussed in Chapters 3 and 4, respectively.
