Opis:
The aim of the study was to determine the structure of tap water consumption in rural households. The structure was analyzed based on direct measurements of water consumption carried out in the years 2011–2014 in 70 households in Rybna (Czernichów commune, Małopolska region). Thanks to two metering points (water supply connection and water supply point outside a residential building), it was possible to determine water consumption for the household and other purposes. The collected data indicated significant discrepancies between actual water consumption and those recommended in various guidelines. The analysis of water consumption structure showed that these discrepancies were also found for the amount of domestic sewage discharged from the rural households. This fact has significant practical implications, as the calculated metrics of unit water consumption are used during design and technical renovation of individual elements of water supply systems and for billing the inhabitants for water consumption in the households without a water meter (lump sum). The study also demonstrated inadequacy of the rule assuming that sewage amount is equal to the amount of water consumed in rural households, which is commonly used in design of sewerage networks and for calculating charges for sewage discharge.

Opis:
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 in fact, only 83.1% of the volume of waste water was discharged in the form of waste water to the sewage system. The remainder was called. non-returnable water consumption for additional purposes.
