Water plays an important role in the processes present in ecosystems, and constitutes the essential abiotical part of the environment. As a resource which is renewable and changeable in time, the water performs numerous management functions. The nature of those particular functions requires that water is not only protected from contamination, but also economically managed as well. The qualitative and quantitative protection of water resources constitutes and integral part of environmental protection. The present paper describes water-sewage management in Drwinia Commune in Krakow Region (Bochnia Powiat). Particular emphasis is laid on correct management of the water resources available, the quality of surface and underground water resources and the sewage management. The assessment of water management is preceded by the description of the commune itself, in terms of its local development, demography, usage and climate. By analysing the data, it has become possible to state that, although Drwinia Commune possesses sufficient water resources (except for drought periods), the quality of such resources allows them neither to be used for drinking purposes - without prior treatment - nor for farm use. The water resources available include in first row flowing surface waters and underground quaternary waters. The lack of sufficiently developed water ...
Organic sewage of the potato industry is being purified in soil filters – in the form of filter fields established on permeable soils. In seventies of the 20th century they were making an attempt at adopting the conception of agricultural using organic sewage for forest conditions. The forest sewage treatment plant for the Potato Industry Plant in Iława was started up in 1984. For distributing sewers a rain gun was put on with rotational sprinklers. Area of irrigated object covers 216 hectares of pine tree stands in the Iława Forest District (from 2001 the sewage treatment plant was limited to 175 ha). In 1984 a net of 30 piezometers was put on, from what 16 they located on the area of the sewage treatment plant, and 14 outside its borders. These piezometers served mainly for observation of the level of groundwater. A few times a year from some piezometers testers of water were being taken for quality examinations. The aim of the following paper was an assessment of changes of the groundwater quality near the forest sewage treatment plant in Iława, occurring under distribute sewers from the potato industry in 2006–2007 years. A physicochemical composition of testers of water was ...
