Environmental and economic assessment of surface runoff
discharge from railway stations

Summary

Non-point and controlled discharges of raw and insufficiently treated surface runoff from railway stations, bridges and bridge crossings produce a negative impact on the natural state of intersecting or nearby water bodies. The environmental damage of the surface runoff from the railway stations and bridge crossings of the Kuibyshev Railway was assessed for non-point discharge (without treatment); for controlled discharge through the tank; for 70% treatment efficiency; for the treatment to the quality standards for fishery waters. The calculations show that for bridge crossings and small stations surface runoff treatment with 70% efficiency is rational; for medium and big railway stations surface runoff treatment to the quality standards for fishery waters is recommended; for railway terminals only individual design should be applied, possibly with zoning of the territory, due to the large length of up to 5km and the complex layout of railways and availability of enterprises that provide services to the terminal. Preservation and restoration of natural water bodies is possible with certain investments in the protection of the environment provided the water bodies return or approach their original state. For environmental protection measures the economic result is expressed in: prevented damage and an increase in the income of the owner of the facility that affects the water resources region.
