Kansas City, MO Overflow Control Program: Line Creek/Rock Creek Sanitary Sewer Study

摘要

Kansas City’s Water Services Department (WSD) prepared a Long Term Control Plan (LTCP) to provide a roadmap to reduce the magnitude, frequency, and duration of combined sewer overflows (CSOs), and for the rehabilitation and improvement of the sanitary sewer system (SSS) to prevent sanitary sewer overflows (SSOs) and basement backups. The study area for this project includes the sanitary sewer system within the Line Creek, Rock Creek, Buckeye Creek, and Searcy Creek watersheds. The drainage area of these watersheds is approximately 25 square miles north of the Missouri River and contain 8-in to 72-in diameter sanitary sewers. A hydraulic model was developed using XP-SWMM based on data collected from the City’s Geographical Information System. Recommended improvements were evaluated to prevent SSOs, and preliminary cost estimates were developed.
