Possibilities of usability of sediments flowing into a combined sewer network

Primarily there are gravel and sand particles contained, which are, together with the surface runoff, discharged through the rainwater inlets into the sewer system. The concentration of such sediments varies depending on the urbanization density and built infrastructure in the site. In the part of cities with increased occurrence of trees and greenery are the sediments mostly of organic origin (leaves, grass, branches, etc.). With fully functional urban stormwater drainage are these sediments collected directly in the drain inlets and during the dry weather conditions discharged by the authorized persons into the maintain truck. In our research, we focus on the quantity of the rainwater runoff sediments in general view while analysing the possibility and methods of utilization of these sediments.
