Abstract [en]

The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.

The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.

The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.

The work also includes calculation for three different areas for stormwater treatment. Here the areas with different opportunities have been studied. One of them is a low trafficated road, where a vegetated swale has been the solution. For a parking ground, which also includes a road area has a bio filter been calculated. For the third area, a denser trafficated area compared to the first road is studied for the possibility for stormwater drain to areas with soil mixed macadam. All of the solutions have its objective to reduce the pollutants in the stormwater runoff to the recipient. An approximate value for the possibility to collect the pollutions has also been calculated.
