The paper estimates the anticipated changes in the seepage conditions towards the karstic aquifer, the recharge of the aquifer from the combined rainfall, seepage and exploitation as well as the potential alteration in the quality of the aquifer due to the creation of a nearby reservoir. It is shown that despite the somewhat increased seepage of polluted river water towards the aquifer, the quality of the groundwater in the karstic aquifer is not expected to degrade appreciably. However, since the water of the aquifer is used for the supply of neighbouring communities, it is proposed that in the areas where the thickness of the intervening semi-permeable alluvia is small, artificial sealing is installed using either compacted clay or plastic membranes.
