Peak Factors for Sewerage System in Upper Egypt Communities

Abstract

The peak factor (PF) is the proportion of the maximum flow to the average daily flow in a wastewater system. Both of the average and the maximum daily flow are evaluated randomly because there is difference in their values, therefore the corresponding peak factor (PF) may be explained based on a probabilistic theory. In this study, Peak factor equations were developed for different studied areas in Upper Egypt region with different populations and water consumption. Ten years of flow data was collected and measured for the study areas and analyzed to improve the P.F equation. The flow values and P.F values acquired from the developed equations of the studied communities were compared to equations from previous studies
