This paper presents an empirical verification of the demand price elasticity for piped water in major cities in Poland – it was the main goal of the research. The information concerning the demand reaction to price changes is substantial for sustainable urban water demand. Any prediction of possible adaptation to global climate change also requires detailed information about consumer behaviour related to water consumption. This study was conducted on panel data consisting of approx. 100 largest Polish cities over the period of 5 years: 2010-2014. It was the second analysis in Poland and the first conducted on individual data from Polish agglomerations, instead of aggregated data for the whole country. Such detailed level of disaggregation has also some disadvantages – due to the lack of income data for each city – the income elasticity was skipped in the model. Finally the results were in the same range as figures obtained in other EU countries.

Artykuł prezentuje próbę empirycznej weryfikacji wskaźnika elastyczności cenowej popytu na wodę na bazie danych z dużych miast w Polsce. Informacje związane z reakcjami popytowymi odgrywają istotną rolę w procesie zrównoważonego zarządzania zaopatrzeniem w wodę. Metody dostosowania się do globalnych zmian klimatycznych również wymagają znajomości zachowąń konsumentów w zakresie popytu na wodę. Badania wykorzystywały bazę złożoną z danych opisujących 100 największych miast w Polsce w okresie 2010-2014. Było to drugie badanie elastyczności cenowej popytu na wodę w Polsce a pierwsze oparte o dane z pojedynczych aglomeracji – zamiast danych zagregowanych dla całego kraju. Tak duży poziom szczegółowości kreował również pewne trudności – w skali poszczególnych miast brak jest danych o dochodach – stąd też pominięto zjawisko elastyczności dochodowej popytu na wodę. Otrzymane wyniki nie odbiegały znacząco od wcześniejszych badań realizowanych w krajach UE.

The article presents the conceptual research on the management of rainwater in the Straconka stream catchment, most of which is located within the territory of the city Bielsko-Biała (Poland). The study was focused on the possibility of using rainwater for flushing toilets in order to reduce the consumption of treated tap water (intended for consumption). Sanitary use of rainwater requires its collection in a tank of appropriate capacity. The selection of the tank depends on the roof area, the number of residents generating water consumption and the technical possibilities of the installation. To conduct the simulation, all buildings were inventoried, the roof area was determined. Data on the number of residents were also included. In turn, data on the amount of atmospheric precipitation in the study area enabled determining the degree of coverage of the demand for rainwater for flushing toilets. The analyses were conducted for single-family housing, multi-family multi-level housing (blocks), terraced multi-family housing as well. In the first and third cases, it was proposed to implement individual closed tanks, while in the case of blocks of flats, open tanks were used. It was demonstrated that the use of rainwater tanks allows for a significant reduction in the consumption of treated water. In the case of single-family housing, the use of a domestic tank with a capacity of 250 dm3·person-1 would reduce the consumption of treated water in the toilet by 95.8%. For multi-family multi-level housing, the construction of one open retention tank with a capacity of 300 m3 would reduce the consumption of water in toilets by 51.6%. In the case of terraced multi-family housing, the use of a domestic tank with a capacity of 350 dm3·person-1 would reduce the consumption of water in toilets by 90.8%. For the purpose of selecting the individual tank capacity, a nomogram was formed that takes into account the roof area per resident.
