WP 5.1 - In situ measurement of road drains

Project partners
Sieker (Dr. Harald Sommer)

Short description
The goal is to prepare and carry out pollution load simulations with the hydrological pollution load model STORM-SEWSYS. The model takes into account the accumulation of the emissions and the influence of rain events on the erosion for the calculation of particles entering into the sewer system. STORM-SEWSYS will be extended and adapted for use as part of the project. In addition to freight generation on the basis of DTV (Daily Traffic), approaches for freight generation at load points and road sections with different section characteristics, which are simulated during tire tests, are being developed. The load values correlate with the tire abrasion at the respective load points. This is integrated into SEWSYS via a load factor to be developed and parameterised for practical use. The further developed model will be tested using a sample area. The findings from BSR‘s street cleaning services are also going to be incorporated here. For the transfer to the investigated catchment areas, the hydrological pollution load models utilise an adapted model.



WP 5.2 - Potential estimation of de-/central rainwater treatment plants

Short description
The aim is the integration and parametrization of decentralised treatment plants, such as filter inserts in road drainage shafts, rain clarifiers and retention soil filters in SEWSYS. The existing data for reducing the AFS/AFS63 content of technical treatment systems (decentralised/centralised) are used to estimate the retention potential for tire particles. For this purpose, the systems are integrated into the created models by IPS with STORM for specific catchment areas. An estimate of the cleaning performance of decentralised treatment plants should be made mainly with regard to AFS63 as a sum parameter. Conclusions on the retention of tire abrasion can then be drawn from the proportions of the corresponding fractions determined in the project. The model created in WP 5.1 is used to simulate the catchment areas. The estimation of the potential of the plants is based on the results of existing research projects and the measurements within the framework of the RAU research project.
