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 ofcombined sewer overflows (CSOs), and for the rehabilitation and improvement of thesanitary sewer system (SSS) to prevent sanitary sewer overflows (SSOs) and basementbackups.The study area for this project includes the sanitary sewer system within the LineCreek, Rock Creek, Buckeye Creek, and Searcy Creek watersheds. The drainage areaof these watersheds is approximately 25 square miles north of the Missouri River andcontain 8-in to 72-in diameter sanitary sewers.A hydraulic model was developed using XP-SWMM based on data collected from theCity’s Geographical Information System. Recommended improvements wereevaluated to prevent SSOs, and preliminary cost estimates were developed.
