Non-Uniformity of Water Demands in a Rural Water Supply System

Joanna Gwoździej-Mazur , Kamil Świętochowski

Abstract

The increasingly frequent use of computer simulations for the calculations concerning the water supply systems requires accounting for the demand patterns. Determining the coefficients of daily and hourly non-uniformity is indispensable for the correct designing or modernization of pipes in the water supply network. The first goal of article was to obtain the non-uniformity index for the preparation of hydraulic models in rural water systems called “N” system and “CWK” system. In this article, the authors present the results of the water consumption analysis in two rural water supply systems. The article presents the water consumption non-uniformity factors calculated over the course of a year, a month and a day. The article also included the calculated water demand curves over the course of a day, showing the variability of water demand with characteristic morning and evening water consumption peaks and changes of the consumption curve in the prospective development of the water supply network, where industrial consumers would become the main water consumers. The research material consisted of the water consumption measurements in two rural water supply networks situated in northeastern Poland, taken over the years 2010–2017. The article also shows the water demand curves in the studied rural water supply networks for every day of the week. The values of minimum and maximum hourly non-uniformity coefficients were compared to the mean value of these coefficients. The changes in the values of minimum and maximum hourly coefficients with respect to the mean value for the given hour may differ from -89% to +85% for hours of minimum demand. The changes in the values of minimum and maximum hourly coefficients with respect to the mean value for the given hour may differ from -16% to +30% for hours of maximum demand.
