Designing the project of surface runoff treatment facilities in Samara

Summary

The results of developing design and engineering documentation of the main intercepting sewer and treatment facilities for surface runoff from the drainage area of the Volga downhill of Samara are presented. The runoff produces a negative impact on the river intake of the two main municipal pumping-filtration stations. Designing and constructing these projects are implemented within the frames of the high-priority activities envisaged by the Master Plan of Samara approved in 2008. The route of the main rainwater sewer approved in the project provides for the possible connection of eleven outfalls discharge untreated surface runoff into gulleys of the Volga downhill. The process of surface runoff treatment envisages four stage water treatment with flow rate and pollutant concentration equalization in accumulating tanks: the first stage – mechanical treatment (screening, sedimentation in grit chambers and accumulating tanks); the second stage – physical and chemical treatment (coagulation of pollutants, sedimentation in laminar settling tanks); the third stage – enhanced treatment (filtration in contact clarifiers, two-stage filtration in sorption filters with MIU-S media); the fourth stage – UV water disinfection.
