The irregularity of water consumption in settlements with varying numbers of inhabitants

Abstract

The article presents an analysis of water consumption in selected settlement units of Lower Silesia and Lubuskie Provinces, with the number of inhabitants varying from less than 200 to more than 8000. Based on data over several years, values characterizing water consumption in individual systems were calculated, i.e., the indicator of water consumption per capita as well as hourly and daily irregularity coefficients. Consumption during various time frames – in individual months of the year, days of the week and hours of the day - was also compiled. The obtained results were the bases for comparison with values provided by Guidelines, which are the basis for calculating for water demand; and Regulation, which is the basis for billing water consumption, as well as with the results of other authors. Tendencies characterizing water consumption in the subsequent years were also indicated. A typical weekly and daily (24-hour) course of consumption was observed, with the course being characteristic of small settlements with varying numbers of inhabitants.

Research on the Hourly Water Consumption Structure in Rural and Suburban Household

“…The hourly water consumption in the suburban household differed from the hourly water consumption in the rural household, showing at the same time, similar trends in hourly and weekly water consumption as in the urban and rural water supply system analyzed by Ogiołda and Nowogoński [2018]. It was noted that in the whole research period, the suburban household (Fig.…”

“…Similar research by Chmielowski et al [2009] concerned the variability of water consumption in residential buildings in one of the cities of the Southern Poland during a six-year period. Despite the structure of water consumption in daily and weekly cycle has already been quite well known (typical peak water consumption in the morning, in the evening and at weekends), in the case of individual users, the structure of water consumption may differ from each other [Ogiołda and Nowogoński 2018]. Update and modification of design guidelines should take into account not only the decrease in water consumption observed in so many cases Pasela 2015, Pawełek 2016], but also other factors affecting the water consumption.…”

Analysis of the Impact of the Air Temperature on Water Consumption for Household Purposes in Rural Households

“…household functions and features along with the outdoor activities, the age and the number of residents and their individual habits, residents earnings, and thus, water use and sewage disposal fee as well as the degree of the households equipping with plumbing fixtures and appliances [Domene and Sauri 2006, Fan et al 2013, Rathnayaka et al 2014, Hussien et al 2016, Bich-Ngoc and Teller 2018, Ogiołda and Nowogoński 2018]. Irregularity of water consumption on an annual basis should be considered in relation to the seasons; similarly to the monthly water consumption irregularity, this is related to the impact of meteorological conditions on water intake.…”
