The impact of temperature anomalies on sudden increase in water production and consumption

Cieżak Wojciech, Kutyłowska Małgorzata

Environment Protection Engineering

2024

Vol. 50, nr 4

115--126

The paper presents the influence of weather conditions on water consumption in two selected water-pipe networks. The analyzed problem seems to be significant because even several days with extremely high temperatures cause exploitation difficulties in the distribution system due to water consumption exceeding the average. Water companies should be prepared for complications in exploitation when even whole water from reservoirs is supplied to the network. The obtained results show that a high correlation between anomalies in temperatures and water consumption exists, especially during weekends. The Pearson coefficient varied between 0.76 and 0.88 which means that the temperature has a significant influence on water demand. The aim of the work was also to note that reasonable usage of tap water by individual consumers can influence the security of water distribution. On days when extremely high external air temperatures are forecasted, water consumption for nonessential purposes, such as watering gardens or filling backyard pools, should be limited.
