The paper presents an analysis of daily water consumption for household purposes carried out within one year in a selected rural household. The study was undertaken because so far the guidelines for designing rural water supply systems have not been updated for a very long time and needed verification. It involved a comprehensive system for measuring water consumption equipped with automatic readers and data recorders. The research clearly showed that actual water consumption was much lower than that provided in the current guidelines, and confirmed significant variability in water consumption for household purposes depending on the day of the week. Moreover, variability of water consumption within a year, determined by daily variation coefficient, was found to be much higher than that provided in the guidelines.
This article presents the results of a study on hourly and daily variations in water demand patterns, depending on a season. The study was conducted in the years 2014-2015 on a selected rural water supply line. The analysis was based on values of hourly water demand as measured by a water meter coupled with a recording device. The research showed that both the volume and fluctuations in daily water demand were higher in the spring and the summer, versus the autumn and the winter. This was most probably caused by water consumption for additional purposes, specific for rural areas. Individual water demand was the highest in the summer, and the lowest in the winter. Two peaks for hourly water demand were determined for the analyzed seasons. The morning peak always occurred at 7 a.m. on working days, while on days off work it fell at 9 a.m. or 10 a.m., depending on the season. The evening peak always fell at 8 p.m., regardless of a season or a day of a week. On working days, the evening peak was always higher than the morning one, while on days off work the morning peak was higher than the evening one in the autumn and in the winter, and both peaks were the same in the spring and in the summer.
