Problems of water supply to seaside localities of Poland

Problems of water supply to seaside/resort localities are considered in the paper. The main task is to supply water of proper quality and amount at seasonal fluctuations in the demand. The paper focuses on the operation of water supply systems in the following localities of Central Pomerania: Mielno, Unieście, Mielenko, Sarbinowo, and Chłopy. They are main summer resorts of the region with typical fluctuation in population during the annual cycles affecting the amount of water supply. The atmospheric conditions, mainly temperature, generally affect the magnitude of water demand. The water-pipe system under consideration forms a very interesting technical solution for supplying both administration-industrial agglomeration, that is the municipal system, and localities lying in the seaside strip characteristic. The water intake is located in Mostowo which lies 19 km away from the main city centre of Koszalin.
