Development of a combined drainage system within the boundaries of the historical settlement of Samara

Summary

The paper dwells upon the development of a combined drainage system within the boundaries of the historical settlement of Samara. The issues of centralized storm sewer systems that discharge their effluents into the Saratov reservoir, are considered. Of particular interest is the historical part of the city where architectural and historical monuments are located including an egg-shaped sewer laid at the beginning of the twentieth century. The effect of water consumption reduction on the fill rate of the pipelines and underloading of the municipal wastewater treatment facilities is shown. The physicochemical composition of surface runoff, as well as maximum permissible concentrations for the Volga River are considered. To correct the situation, using regulating (storage) tanks is proposed to develop a centralized combined drainage system at ten outfalls into the Volga and Samara rivers. A general sequence for the regulation, treatment and discharge of surface runoff has been developed presented in the horizontal diagram of the discharge of surface runoff. Possible development of a combined drainage system with the use of regulating tanks in a public storm sewer for the outfalls located within the boundaries of the historical part of Samara will solve the problem of removing surface runoff and provide for the partial additional workload on the municipal wastewater treatment facilities.
