Present Situation and Prospects of Water Economy in the Luciąża River Basin
Languages of publication
The author presents the present situation and the most urgent tasks concerning the water economy in the area of the river basin (760 km ) threatened with water deficit, the western part of which will be soon encompassed by a depression funnel of Bełchatów lignite mine. The Luciąża river, left tributary of the Pilica river flows into the Sulejów reservoir. The average flow of the river at its mouth reaches 4,7 ms per second. The river water in the Luciąża basin is mainly used for agricultural purposes, and, first of all, for irrigation of ameliorated grassland (ca. 2,000 hectares), and for supplying fish ponds with water (ca. 150 hectares). Water requirements of the population and the industry are supplied by the underground water with about 70 per cent of all farms using shallow topsoil and alluvial waters. Water supply systems in rural, areas are few and far between. The most important tasks facing the water economy in the Luciąża river basin include: - improvement of purity of the Luciąża river and its main tributaries so that they do not impair the sanitary level of the Sulejów reservoir; - ample provision of water for agriculture and forestry, first of all for the area which is directly affected by the Bełchatów lignite mine through construction of central water supply systems based on deep intakes of the underground water and transfer of water from other river basins (the Pilica and the Widawka rivers) as well as storage of it in agricultural storage reservoirs. Bigger reservoirs should be built on the upper course of the Luciąża and the Bogdanówka. Water deficit in the Luciąźa river basin for 1985 is estimated at ca. 40-50 million cubic metres.
