The dynamics of water intake for different purposes from the Ararat artesian basin has been studied in connection with the overuse of water by fish farms in Ararat Valley. It has been shown that as a result of those negative processes the surface area of groundwater with positive pressure has decreased by 3 times, 31 communities are partially or completely deprived of water obtained from fountain boreholes for various purposes. As a consequence of the decline in groundwater level irrigation norms of agricultural crops have increased by 25% or about 14 million m 3 , the physical properties of soils have deteriorated on the area of 7 thousand hectares. It has been proposed to reuse discharge waters from fish-farms for irrigation. Through technical and economic calculations, it has been shown that in case of solar station-pump station-irrigation pipeline construction the cost price of irrigation water per 1 m 3 is 8-10 times cheaper than in case of reservoir construction and irrigation water supply systems.
