One of the main problems facing big industrial cities is wastewater with hazardous substances, including petroleum products.A study of methods for optimizing spillways of city flume networks in Shymkent in South Kazakhstan region is presented in this paper.The influxes of flume networks and drainage (ground) water into existing rivers allow determining the aggregate intermediate volume (over a certain period) of surface runoff that enters the watercourses after rains.The estimations were based on data, collected at points of accumulation of surface water and rainwater, discharged into the Badam, Koshkar-Ata, and Karasu Rivers via optimal routes, in accordance with the methods of estimating the discharge of storm runoffs from the territory of settlements and enterprises.The paper characterized water discharges in the city by pollution categories and their nature, presented the main operating parameters of city treatment facilities, provided methods of estimating rainfall floods, a hydrological characteristic of estimated watercourses in the city, and determined the zoning of watercourses for rainwater and meltwater in the city territory.
