Prevention and control of sewer system overflows

"The purpose of this Manual of Practice is to provide the information necessary to help managers and engineers understand and analyze an overflow problem (dry weather, CSO [combined sewer overflows], or SSO [sewer system overflows]) and provide guidance in finding the best strategies to reduce or eliminate it. It is also intended to serve as a planning guide in developing long-term control plans for CSOs and SSOs." -- p. xxxi.
