Rain Precipitation Parameters for the Design of Surface Effluent Treatment Facilities from the Territory of Industrial Enterprises

Abstract

Data on the maximum layer of precipitation for rain, the drain from which is allocated to treatment facilities from the territories of industrial enterprises in the conditions of the Russian Federation, are presented. The results are analysed and summarized. The average layer of precipitation with a period of single excess equal to 1 year according to 195 weather stations is determined. The average precipitation layer for the entire area under consideration was 27.8 mm, with a variation range of 12.3 to 72.0 mm. The obtained parameters are intended and can be used for design of surface runoff treatment facilities.
