SUSTAINABLE USE OF GROUNDWATER RESOURCES IN TERMS OF INCREASING THE CAPACITY OF TWO INTERCONNECTED GROUNDWATER SOURCES: A CASE STUDY BECEJ (SERBIA).

The existing groundwater source for the public water supply of Becej city in Serbia tapping groundwater from three water-bearing horizons over 15 wells with summary capacity of 100 l/s. Near the public water source of Becej exists groundwater source for industry with capacity of 12 l/s which tapped same horizons. In the coming period is planned to increase summary capacity of this groundwater source up to 57 l/s. Also, the increase of summary city's source capacity is planned for 50 % in the next few years, that is means an increase of groundwater abstraction for an additional 84 % from the same water-bearing horizons. This paper presents both the effects increasing of the capacity of industry water source to public water source and interaction of increasing the capacity of both the source with the assessment of possibilities for future sustainable use of groundwater a period of 10 years of such exploitation. The impacts of increasing the capacity of both sources are simulated on a hydrodynamic model in seven variants and quantitatively shown through the development of further depression in the exploitation wells.
