The work analyses the eight-year (1997–2004) period of research on water consumption by a selected household in a housing estate in Krakow. Water consumption was referred to the number of persons using water in the investigated household, a unit consumption was determined and daily irregularities in the uptake of water. The household numbered four permanent dwellers. The basis for analysis were daily indications of water meter registered in the observation journal, temporary changes of the number of inhabitants and water use outside the flat, e.g. for garden watering or car washing, etc. The investigated building is fully furnished with running water and sewer system, i.e. running water is supplied to the flat furnished with kitchen sink, flushed toilets and two fully equipped bathrooms. In the initial period of investigations, wastewater from the building was directed into a cesspool but since November 1997 it has been drained by common sewer system. Obtained research results revealed that daily unit water use in 1997–2004 ranged between 5.9 and 693.3 dm3∙M-1∙d-1, whereas average unit daily water consumption fell within the 135.5 and 177.5 dm3∙M-1∙d-1 depending on year. The biggest difference between average daily unit water uptakes in individual months was registered in 2000 and ...
The article presents the results of water consumption analysis by two groups of users connected to the waterworks in Jordanów. The first group included 33 one-family constructions (detached houses) consisted of families with 1–8 persons, the second included 20 households of multifamily constructions (blocks of flats), that consisted of 1-7 persons. Water consumption was measured on the basis of the water meters readings, in two to four months intervals (53 to 125 days) in detached houses and in months’ intervals (28 to 33 days) in blocks of flats. The testing cycle lasted over three years (from 08.03.2002 to 30.06.2006) in the case of the one-family constructions and over two years (from 24.01.2004 to 26.06.2006) in the case of the multifamily constructions. The highest converted average daily water consumption for the detached house (containing 5 people) in the analyzed period was 597,70 dm3·d-1. It showed the 97,5% difference from the average value, which in this type of buildings amounts amounted 302,69 dm3·d-1. In the blocks of flats (multifamily constructions) the maximum converted average daily water consumption was 484,67 dm3·d-1 (with 7 people in the building). It varied a lot from the average value for this type of buildings, which amounted 245,97 ...
