Optimization of the building process of ground water intakes under the conditions of natural water resources deficits

The article discusses the problems of optimizing and exploiting ground water intakes during times of natural water resource deficits, which are critical sources for the operational resources needed. A deposit of underground water in Rudno in the Lviv region of Ukraine is used for the investigation. To optimize the withdrawal of water for the population in the given district, given the limited natural water resources, and on the bases of a detailed geological, hydrogeological and the hydrological analysis of the area and a review of the literature, a permanent mathematical model for filtration of the chosen deposit was created to evaluate the operational groundwater resources for a long-term period. The model allows for the simulation of water intake exploitation in different operating regimes in order to solve the problems of regulating and optimizing water withdrawal under different conditions of change in the water intakes, expanding productivity depending on the economic needs in the region, and solving problems related to the quality of the drinking water by predicting the possible pollution and depletion of major aquifers during their operation. The model of the Rudno water deposit can be used as a reference when selecting promising sites for new water intakes to reduce material and energy resources during construction.
