Assessment of the Possibility of Using Treated Wastewater for Irrigation in the Republic of Crimea

Abstract

The possibility of using wastewater in the Republic of Crimea for irrigation of agricultural crops was considered, the volume of which in 2021 amounted to over 50 % of the total water intake for national economic needs from all sources. It is shown that a significant part of the wastewater after its additional purification and water treatment can be used in irrigated agriculture in the Azov Sea basin, where there are agricultural lands prepared with irrigation. It is concluded that the use of other wastewater will require reconstruction and modernization of treatment facilities, drainage systems and the creation of utilities for the accumulation of wastewater, its post-treatment for irrigation purposes and transportation to irrigation systems.
