A comparative analysis of the formation of the nutrient load caused by the formation of communal discharges from the urban population and the dispersed load from the rural population for the period 2002-2015 yrs was carried out on the catchment of the Kuibyshev reservoir within the boundaries of the Republic of Tatarstan. It was revealed that the average value of the mass of nitrogen and phosphorus compounds formed in the catchment from municipal wastewaters of the urban population over the period is N tot 5343 tons, P tot 1790 tons; from the dispersed load of the rural population N tot . 515 tons and P tot 207 tons. It is shown that the contribution of the nutrient load from municipal wastewaters of the urban and rural population is N tot . 96,3% and 3,7%, and according to P tot . 96,9% and 3,1%, respectively.
