TransMiT - Resource Optimisation of Mixed and Separating Drainage in Existing Urban Districts with Intensive Settlement Pressure

Project duration: 04/2019 to 08/2022

The scientific objective of this project is to illustrate and assess, how aspects of urban development can be combined with aspects of water development in consideration of resource efficiency. Therefore, three typical urban districts will be analysed by using different research approaches. Its focus is on the transforming aspects of the technical and organisational transformation of separating and mixed drainage.

The increased number of sealed surfaces and the more frequent heavy rain events occurring due to climate change can be a burden on existing sewage systems due to higher peaks when water runs off. In the course of that regulatory requirements have been exacerbated in the last few years. The scientific objective of the subproject at the Technical University of Dortmund is the scientific study of retention capacity of (flat) roofs. The analysis of the suitability and eligibility of (flat) roofs contain discharge measurements, the scientific monitoring and the evaluation of the results. In the final step this knowledge should be transferred to other urban districts.

Location & approach

The TU Dort­mund campus is located near the Dort­mund West interchange, where the A45 Sauerland line crosses the B1/A40 Ruhr expressway. The Dort­mund-Eichlinghofen exit on the A45 leads to the South Campus, the Dort­mund-Dorstfeld exit on the A40 leads to the North Campus. Coming from the A45, you can turn onto Stockumer Straße via Universitätsstraße. This in turn is connected to Baroper Straße, along which Campus South extends. If you take the exit of the A-40, the route via Emil-Figge Straße, Marie-Curie Allee to Baroper Straße makes sense. If you turn from Baroper Straße into August-Schmidt Straße, you have the possibility to reach the parking lot directly behind the GB III.

The South Campus is connected via Stockumerstraße by bus lines 440 and 449, which run every 10 minutes. Campus South can be reached on foot from the Am Gardenkamp stop, and the Eichlinghofen H-Bahn station is also located near the Eichlinghofen stop. The bus lines connect to the U42 light rail line at the Barop Parkhaus stop, which provides connections to the Dort­mund-Hombruch district and Dort­mund downtown. 

From Dort­mund-Eichlinghofen, the South Campus is connected to the H-Bahn network via the Eichlinghofen H-Bahn station. Line 1 runs here every 10 minutes, and the South Campus is served by the Campus Süd stop. 
A connection to Campus North is also provided via the H-Bahn. Line 2 shuttles between Campus North and Campus South every 5 minutes.

The AirportExpress is a fast and convenient means of transport from Dort­mund Airport (DTM) to Dort­mund Central Station, taking you there in little more than 20 minutes. From Dort­mund Central Station, you can continue to the uni­ver­si­ty campus by interurban railway (S-Bahn). A larger range of in­ter­na­tio­nal flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the uni­ver­si­ty station.

The facilities of TU Dort­mund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the uni­ver­si­ty are located in the adjacent “Technologiepark”.
