Who we are

RPTU Kaiserslautern-Landau , Department of Urban Water Management

The Department of Urban Water Management at the RPTU Kaiserslautern-Landau, Department of Urban Water Management deals with conceptual issues relating to the planning and operation of the entire (waste) water infrastructure in settlements. Here, the activities of an engineer merge with the requirements and tasks of environmental protection. The solutions to scientific problems combine different engineering and natural science disciplines, also taking into account economic, social and urban planning aspects.

In particular, the department has many years of research experience in the field of urban drainage and the handling of stormwater in urban areas. Important, ongoing fields of work and research are municipal heavy rainfall risk management, the hydraulic performance of municipal drainage systems, and the modelling, simulation, and optimization of wastewater systems.

Amt für Landschaftspflege und Grünflächen

With almost 900 employees, the Office for Landscape Management and Green Spaces is one of the largest offices in the City of Cologne and is responsible for the green cityscape in all its facets. In addition to the care and maintenance of green spaces and parks, it also includes landscaping measures such as the planning of new resilient green spaces and the implementation of ecological concepts.
The focus is always on creating and preserving local recreation for the urban population and sufficient habitats for animals and plants at the same time.

Berliner Wasserbetriebe AöR (BWB)

Berliner Wasserbetriebe (BWB), as a public utility is responsible for drinking water supply and wastewater disposal for the 3.6 million inhabitants of Berlin and id therefore Europe’s largest integrated water utility. BWB and its predecessor organisations have been responsible for urban water supply and sanitation in Berlin for 160 years. BWB has a department of R&D with an annual budget of 2.5 Mio € on research. BWB is currently involved as partner or coordinator in 35 projects funded by national and international programmes.

Ecologic Institut (EI)

Ecologic Institute is an independent, academic think tank for environmental research and policy analysis. Since its founding in 1995, Ecologic Institute has been dedicated to improving environmental policy, sustainable development and policy practice. We are committed to mainstreaming environmental issues into other relevant policy areas. We research, support and evaluate political processes on the local, national, European and international levels, bringing together actors from academia, policy making and practice. The results are in-depth analyses and innovative recommendations.

Helix Pflanzensysteme GmbH

Helix Plant Systems GmbH offers greenery for a wide variety of projects and requirements. All products and product forms are characterized by the fact that vegetation is established on the most difficult vertical surfaces and can grow and thrive sustainably. These are almost exclusively intensively greened areas that have a high water requirement, especially in the summer months. The Helix plant systems are always part of the urban green infrastructure and thus make a lasting contribution to reducing the heat island effect in urban areas and, with their extensive ecological services, ensure an improvement in the living environment. In order to create a dense network of green infrastructure, functional expansion of rainwater management systems to prevent heat and drought is essential. With its economic activities, Helix can be seen almost directly at the interface as a buyer of recyclable water. The use of drinking water for the systems mentioned should only be necessary in exceptional cases in the event of an accident and is prohibited from an ecological and ethical point of view, especially since drinking water will presumably become scarcer and more expensive in the coming years as a result of climate change.

ISWA der Universität Stuttgart

The Institute for Sanitary Engineering, Water Quality and Solid Waste Management (ISWA) at the University of Stuttgart has been dealing with engineering and management tasks in the areas of drinking water, wastewater, water recycling, waste and exhaust air since the 1950s. With a total of over 100 employees, test facilities, workshops, laboratories and its own large-scale teaching and research sewage treatment plant, it is equipped for research, university teaching and professional training.

In addition to improving the cleaning performance of wastewater systems and optimizing water treatment processes, the Department of Multiscale Environmental Process Engineering - until 2021 Chair of Urban Water Management and Water Recycling - develops concepts and technologies for the integrated handling of drinking water, rainwater and wastewater flows in settlement areas with the aim of progressive urban water management , i.e. high supply and disposal convenience with the best possible water protection and sustainable resource and energy management at the same time.

Senate Department for Urban Development, Building and Housing

The Berlin Senate Department for Urban Development, Building and Housing forms part of the Berlin State government. It is one of ten specialised departments of the Berlin Senate. The Senate Department for Urban Development, Building and Housing covers a wide range of topics: new residential development, housing subsidies, rent control and tenant protection, promotion of urban development, architecture and urban design, real estate policy and land-use planning, urban land-use planning, the direction of municipal housing associations, our joint state planning with Brandenburg, geo-information, public buildings for culture, science, education, sports and justice, as well as architecture and open space competitions. The Senate Department for Urban Development, Building and Housing carries the responsibility for a social and sustainable urban policy. One of our main goals is therefore the timely construction of new housing that is affordable and climate-friendly. For this purpose, we plan and develop new urban neighbourhoods and fast-track procedures for planning, approval and construction processes. At the same time, we maintain social cohesion through tenant protection and neighbourhood management. We aim for a city where all Berliners may thrive – regardless of income and origin. Diversity is in our DNA. We are a city brimming with possibility, tolerance and openness. A true urban development for the people of Berlin must therefore be based on these values. Our urban development policy goal is an affordable, socially just and vibrant metropolis.

Berlin Senate Department for the Environment, Urban Mobility, Consumer Protection and Climate Action

The Berlin Senate Department for the Environment, Urban Mobility, Consumer Protection and Climate Action is one of ten departments of the Berlin Senate. It is part of the state government and the supreme state authority responsible for environmental, urban mobility, consumer protection and climate action policy in the German capital. The aim of the Senate Department is to make Berlin healthier, more mobile, safer and more climate-friendly. To this end, it creates, among other things, sustainable mobility for all Berliners, takes care of the infrastructure - from cycle lanes to trains and buses to roads -, clean air, living waters and a balanced urban climate.


Dr. Jakob Sohrt

StEB Köln

As a municipal drainage operation, our main tasks are wastewater disposal, flood prevention and the management of small rivers and park ponds in the Cologne urban area - we actively shape the water cycles in the city. Our work directly affects all people in Cologne as we are a service provider in the water industry and an essential component of public services. In the course of the projected climate change and its associated extreme weather events an important focus is to develop and apply a sustainable rain- and stormwater management to sustain a safe living environment.



Luisa Schwab

Technologie Stiftung Berlin

With digital tools and smart solutions, urban coexistence can be designed to be more open, worthwhile and sustainable. That is why the Technology Foundation Berlin is committed to digital transformation in city administration, education, culture and commerce – orientated towards the common good and transparent.

Many of our projects are flagship projects that demonstrate the opportunities of digitalisation and profile Berlin beyond city limits. With our studies and reports, we ensure that the latest technological developments are identified early on and leveraged for the transformation process. Our digital educational programmes pave the way for everyone to participate in the transformation and enjoy its benefits.

For a Berlin that is worth living in tomorrow.
