TransMiT

Studies show that stormwater in urban areas is heavily contaminated with pollutants. It cannot simply be discharged untreated into the receiving water bodies. The TransMiT project will develop adaptation strategies for resource-efficient urban district planning. Using a holistic stormwater management approach, various decentralized measures as well as existing infrastructures such as combined sewer systems and sewage treatment plants are combined in order to gradually transform urban drainage into a resilient and economical system. TransMiT provides recommendations for the transformation of existing districts, taking particular account of conflict and risk management.

The first two years of the project will be used to investigate and evaluate nine pilot plant variations in real life applications. The last year of the project will be dedicated to  potential analyses which will be carried out in two model neighborhoods using the tools and processes developed.

In the work package WP7 of the research project, the Institute of Sanitary and Environmental Engineering, in close cooperation with the Stadtentwässerung Braunschweig GmbH, will investigate the advanced treatment of time-variable micro-pollutants in stormwater using retention soil filters. For this purpose, stormwater is sampled, a real retention soil filter is monitored and a mobile retention soil filter is operated for optimization. The results of the investigations from UP 7 are intended to provide practical water management with recommendations and planning aids for the future construction and operation of retention soil filters for the pre-treatment of stormater.
