A new planning procedure for sewer flushing
TL;DRAbstract
Based on results of extensive field studies and mathematical simulations a new practical method to plan flushing measures for sewer cleaning has been developed. Objective of the new planning procedure is to improve the current practice of cleaning sewer networks. In focus of the procedure stands the composition of a problemspecific flushing program consisting of three parts: the determination of start (basic) values of the dimensioning parameters dam-height (H0) and flushing volume (V0), the adaptation of the basic values if structural boundary conditions demand it and the configuration of flushing waves by empirical knowledge. The use of the new method is primarily restricted to the operation of storage-volume-activating-devices in manentry-sewers with circular cross-sections.
