On the regulation of surface runoff handling

Summary

An analysis of a number of amendments included in the current version of CP 32.13330.2018 «SNiP 2.04.03-85 Sewerage. Pipelines and wastewater treatment plants», in terms of designing systems for the surface runoff disposal and treatment, as well as possible options for regulating surface runoff discharges into public wastewater disposal systems and water bodies, taking into account the requirements of the current environmental legislation is presented. An assessment of the effect of the negative environmental impact category of the enterprise on the regulatory requirements to discharged wastewater is given. It is shown under what conditions and under what category it is advisable for an enterprise to operate its own surface runoff outfall to a water body or discharge wastewater into a public sewer.

Issues of classifying surface runoff, treatment technologies and methods (for the discussion)

Summary

An analysis of the qualitative composition of surface runoff and treatment requirements depending on the characteristics of the effluent receiving water are presented. A comprehensive approach is proposed while choosing process solutions and the basic composition of the treatment facilities to achieve the required treatment efficiency. For the implementation a classification of surface runoff and the main treatment processes with differentiation depending on the regulatory requirements to the effluent has been developed. The proposed classification provides for unifying the procedure for choosing the main process solutions.
