The article raises the issue of the ecological state of storm wastewater, their technical condition. The issues of assessing the functioning of storm sewers are included in the list of municipal environmental control, which is carried out by the executive authorities in the field of ecology and nature management. The research paper outlines the key problems associated with underfunding of the current work to ensure the efficient operation of storm water. The main categories in the system “treatment facilities – storm drains – collectors” are considered. The traditional stormwater runoff system involves the diversion of surface runoff through open water bodies (e.g. river systems). The main environmental indicators to be achieved during the construction and commissioning of a complex of sewage storm treatment facilities have been analyzed. The analysis of the design indicators showed that a total of 18.9 million m3 of storm water, rainwater runoff and drainage waters are subject to treatment. The measures for the installation of sewage treatment plants, storm sewers will prevent the river Volga from entering of more than 22 thousand tons of suspended solids, including heavy metals and 1.2 thousand tons of oil products. According to the project documentation, the construction of more than 50 facilities will allow upgrading the stormwater drainage system of the city of Volgograd within the framework of the National Project “Ecology”. The conclusions reflected in the article reveal the main reasons for the current situation: inconsistency of repair and restoration work to replace parts, assemblies; insufficient amount of technical re-equipment; inconsistency of the chemical composition of wastewater with the established regulatory environmental indicators; insufficient municipal control of the services responsible for this object; insufficient financial support.
