Abstract
The article considers the issue of streamlining of groundwater operational reserves in the State Balance of Minerals of Ukraine, taking into account their development. It was proposed to create within the State balance of mineral deposits of Ukraine a separate reserve of groundwater deposits that had not been developed for 10 years after they were approved. This reserve should also include groundwater reserves, which were tested by decisions of the Scientific and Technical Councils of industrial geological enterprises of the Ministry of Geology of the Ukrainian SSR and its successors, as well as those reserves, the use of which is not planned as a result of revaluations due to a decrease in water users’ needs.
The proposed changes in the approaches to the removal from the inventory of groundwater reserves of deposits that have not been commissioned for a long time and their further use is impossible as a result of the construction of buildings jf the territory of deposits, their destruction or pollution of groundwater.
