Bridge deck runoff control trough drainage, treatment and irrigation system: The case study of the bridge Ostruznica over the Sava river

Abstract

The paper presents main design project of the bridge Ostruznica deck drainage and runoff treatment. An integral solution of drainage and irrigation and/or discharge water into the Sava river of pre - treated runoff from the portion of highway Dobanovci – Bubanj Potok and the bridge The treated water is taken for irrigation into the groundwater as a recharge, along the series of wells for potable water within sanitary protection zone of the Belgrade Water supply system. The first flush of the criteria rainfall runoff volume is to be pre - treated using a StormwaterR barrels. Such a solution is considered as an additional water source at the aquifer by the rivers’ banks. Also, it is a measure of water cycle improvement. The project is completed by a SwermR preventing system for accidental situation, such as leakage or accidents of vehicles and potential pollution and risks of vulnerability for the potablewater wells.
