At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.

Cheboksary reservoir impact to the coast is manifested in the geophysical impact associated with abrasion activities. Geomorphological area of influence at the moment reaches a width of about 40 m, where are the coasts reformation (erosion, collapse, slumping, sliding, transfer or accumulation of sediments, waterlogged processes). Hydrogeological impact is effect on the level of groundwater. We have proposed the conceptual foundations of functional zoning of the reservoir banks that will help to optimize its operation. Selection zones came in accordance with the principles of landscape planning: 1. The zone of strict water protection: the main purpose – preservation of needing special protection areas. 2. The zone of moderate restrictions: preservation extensively used landscapes. 3. The zone of partial restrictions: improving the pre-emptive particularly vulnerable areas and changing intensity or type of use. 4. The zone of conservation of natural components in agricultural landscapes: ensuring health of the natural environment in the habitats used in agricultural economy. 5. The zone of preservation of vacant space and the natural environment in the settlements: to maintain the required quantity and quality of available green space in the large towns. 6. The zone of improving heavily used areas: elimination of harmful stress and environmental sanitation in the countryside where economic activities and the lack of measures to reduce their risks lead to degradation natural system.
