The paper presents results of direct investigations of water consumption conducted for the period of one year in two rural households in the villages of Włostowice and Stanisławice in the malopolskie province. The first analyzed household had a typically farmer character, whereas the second one was a typical urban household. Both household used exclusively tap water, discharged their domestic sewage into the combined sewer system and were characterized by similar standard furnishing in water supply and sewage disposal appliances. The conducted analysis of water consumption rate revealed lower water consumption by a rural household in comparison with the other of urban character, despite the fact that the first consisted of a higher number of inhabitants and was running plant and animal production. Mean water consumption per convertible inhabitant over the whole period of investigations in this household was 86.1dm3· PM-1·d-1, whereas at Stanisławice household it amounted to 129.91dm3· PM-1·d-1. Irregularity of water intake confirmed so called weakly cycle. The largest water consumption by both households was registered on Saturday and the lowest on Tuesday. On all days of the week, except Tuesday, water consumption by the household in Stanisławice was the higher than by the Włostowice household. Two peaks in ...
The aim of the paper was an analysis of the structure of tap water consumption by rural households considering the use of its results for designing the elements of water supply and sewer systems. The analysis of this structure was based on direct measurements of water consumption conducted in 2011-2014 in 30 households located in Przeginia Duchowna village (Czernichów commune, Malopolskie province). Double measurement of water consumption (water supply connection or water draw off point outside a residential building) enabled the separation water consumption for household and additional purposes from the total water consumption per household. Analysis of the collected data revealed considerable disproportions between the real water consumption and stated in the design guidelines. Calculated on the basis of the study, averaging 85.6 dm3·I-1·d-1, accounted for only 57% of the value of 150 dm3·I-1·d-1 most commonly used in design. Because of the possible determining the water consumption structure it was demonstrated, that the divergences concerned also the volume of domestic sewage discharged from rural households. Obtained results revealed also that application of the principle, where the volume of sewage equals the volume of water consumption by rural households, for designing sewer systems is usually incorrect. In the analyzed household ...
