About the sound
Sounds recorded as the water goes through carbon filters. Filtration on a bed with active carbon improves the colour and taste of water, and also removes metals and other impurities.
The recording was made at the Rudawa Water Treatment Plant, which is part of Krakow waterworks. The water intake is located on the Rudawa River, the left tributary of the Vistula. The raw water from the intake is subjected to a treatment process which consists of oxidation, coagulation, sedimentation, filtration and disinfection. ZUW Rudawa is one of four treatment plants that provide drinking water for Krakow. Tap water in Krakow is of high quality and good for drinking. Its parameters are monitored on an ongoing basis by the Central Laboratory of Miejskie Przedsiębiorstwo Wodociągów i Kanalizacji in Krakow. ZUW Rudawa produces an average of 22,000 - 28,000 m3 of water per day and supplies about 200,000 inhabitants.
