Summary:

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 dm³·d^-1. The converted unit daily water consumption per capita was 86,85 dm³·d^-1·M^-1 in detached houses and 85,1 dm³·d^-1·M^-1 in the block of flats. All analyzed places in the tested period used totally 19817,0 m3 of water, of which 15493,0 m³ was used by 33 detached houses and 4324,0 m³ was used by the rest of the buildings – the 20 blocks of flats.
