Method for estimating the incoming flow of surface runoff in the urban storm sewer

Summary

According to the provisions of the Water Code of the Russian Federation No. 74-FZ and Federal Law No. 416-FZ «On Water Supply and Wastewater Disposal», all enterprises operating public wastewater disposal systems, including surface runoff drainage systems, shall, in accordance with the established procedure, keep a commercial record of the volume of wastewater received by the operated systems, as well as of the volume of wastewater discharged into water bodies. The method for accounting for the volume of surface runoff discharged into public systems of communities and into urban water bodies, as well as the specific features of applying the method with the use of calculations. It is shown that the implementation of justified methods for accounting for the volume of surface runoff discharged from urban territories into water bodies will ensure the reliability and legitimacy of the calculations of the volumes of received (removed) surface runoff in the process of the state monitoring of water bodies, determining the basis of charging for the negative environmental impact and setting tariffs for the customers using sewer network.
