Review article

The article discusses the features of the formation of surface runoff (rainfall runoff and melt water runoff) disposed from the territories of enterprises of the fuel and energy complex. There are presented some data of natural studies of pollution of rainfall and melt water runoff from the territory of boiler houses operating on gas fuel and located in various districts of St. Petersburg. The requirements for the quality of water used in circulating water supply systems of boiler houses are considered. Based on the data of the conducted research, there is proposed a rational scheme for surface runoff disposal, taking into account the possibility of using treated wastewater in the technical (circulating) water supply systems of boiler houses. The proposed scheme for surface runoff disposal will allow reducing the amount of wastewater discharged into public sewerage systems, cutting the consumption of drinking-quality water from public water supply systems, reducing costs and optimizing the industrial water supply scheme of the enterprise.
