Berlin – a modern capital with a long tradition in water management

Berlin, the capital of Germany, is situated at the very heart of Europe’s largest area of interconnected rivers and lakes. And from the first settlements on an island in the river Spree, water has always played an important role in the life of the region. In nearly two decades since the reunification of Germany, the once divided city has been transformed, and the centre of political power is now established in a new quarter on the banks of the river Spree. Water is never very far away in Berlin, you may find it round the next corner or under your feet: hundreds of cast-iron pumps across the city are evidence that the groundwater is always in reach.

1

The pumps are some of the last reminders of the time before the rapid expansion of Berlin in the 19th century. With the problems of providing clean water and discharging sewage representing an obstacle to further development, water management became a topic

of public concern. In 1856, the first waterworks on the river Spree offered a constant piped water supply and the opportunity for water toilets, and at this time work also began on the plans for Berlin’s sewerage system. Wastewater was purified by percolation in outlying sewage farms, a method which is no longer used. The first wastewater treatment plants were constructed in the early 20th century. Continuous modernisation since then has meant that the present six purification plants are always state-of-the-art. This is particularly important in Berlin because although it has many lakes and waterways, it paradoxically has little water. The capital is situated in a region with comparatively low precipitation rates, so that the rivers sometimes even stop flowing during the summer.

2

The river Spree is no longer the direct source of drinking water, which is now completely supplied from groundwater. However, the extraction points are situated near the lakes surrounding the densely settled area, so they are still indirectly using the water of the rivers Spree and Havel through the process of bank filtration. This closed water cycle in a city is a unique feature, and considerable expertise has accumulated about water management. The City of Berlin ( p. 17 ) and the water utility Berliner Wasserbetriebe ( p. 9) have been cooperating for over a century to develop technical systems and to adapt them to the requirements of public supplies and environmental concerns. A research institute ( p. 15) was founded at lake Müggelsee as early as 1893 to investigate and survey the water quality of the lake,

which is important for the drinking water supply of the city. Special attention is still paid to the natural water resources. Recently, detailed studies have been carried out on the processes of bank filtration and artificial recharge of the aquifers as the main source of drinking water for Berlin’s 3.5 million inhabitants. Wastewater purification has been optimised to the limits of conventional biological treatment, so that only membrane technologies could provide further improvements. Rainwater drainage systems have been identified as an important source of pollution. The integrated management of the city’s complex sewerage system is one of the answers to this problem. It is always important to adopt an integrated approach to water and settlement and building structures, and the utilisation of

rainwater in modern buildings is the focus of several projects. The city administration pays special attention to this topic ( p. 16). The quality of the services provided to residents and businesses in Berlin benefits from the high concentration of universities, R &D -institutions and companies:

Research and development of techniques needed in modern water management is the objective of the Technische Universität Berlin with its interdisciplinary Centre for «Water in Urban Areas» ( p. 13). A department of the Freie Univesität Berlin is concerned with hydrogeology and its implications for the technical processes ( p. 14). As a network agency, the Berlin Centre of Competence for Water ( p. 7 ) dedicates its efforts to water research and knowledge transfer both nationally and internationally. The centre acts as a bridge between

scientists and practitioners, and in 2006 it founded the Water Partners Network WaterPN ( p. 8) together with companies in the water sector. In a more general way, the process of innovation transfer is promoted by the TSB Technology Foundation Berlin ( p. 12), acting as a link between politics, research and economy. To meet the constant demand for technical solutions, numerous companies in Berlin and its surrounding region provide skills for every stage of water management. Two of them, Berlinwasser International (p. 11) and Veolia Wasser ( p. 10) are companies with international reputations, the latter being the German branch of the French company Veolia Water. But smaller companies, represented partly by the WaterPN network, also provide outstanding techni-

cal skills and in spite of their size they are active in the international markets. In their commercial activities – national and international – they find support by the Berlin Senate Department for Economics, Technology and Women’s Issues (p. 18 – 19), the Investitionsbank Berlin (p. 21) and the organisation BerlinPartner (p. 20). In addition, the German capital offers direct contact to the federal ministries, to the embassies of the world’s nations and to numerous national and international organisations and institutions. Of particular importance for water management are the GTZ (p. 22) and InWEnt (p. 23) as organisations for international economic cooperation. This concentration of technical, scientific, commercial and political expertise coupled with a special appreciation of water in an urban context makes Berlin a unique source of solutions in water management.

Berliner Wasserbetriebe

Water is our task – Berliner Wasserbetriebe (BWB) provides drinking water and wastewater management for the German capital. Furthermore, the company also manages the drainage and treatment of storm water from roads and public spaces on behalf of the city government. In addition, the sewage of almost half a million residents from surrounding parts of Brandenburg flows to Berlin wastewater treatment plants, and some 100 000 Brandenburg residents drink water from Berliner Wasserbetriebe. Berliner Wasserbetriebe provides about 200 million m 3 of drinking water every year, and with an annual turnover of more than EUR 1.1 billion it is the largest company in Germany’s water management sector. Sustainable operations and strict quality management guarantee best-quality drinking water which fully complies with legal standards, and which lies well below the specified limit values for many parameters. Drinking water is prepared in nine waterworks exclusively from groundwater without chemicals, using near-natural methods.

the comparable level specified in national standards. Without the work of Berliner Wasserbetriebe many innovations that have now set new standards would have been inconceivable – from purification technology and trenchless pipe and sewer laying through to research on riverbank filtration. In the 1990s, a Group was established around Berliner Wasserbetriebe which is active nationally and internationally in various water-related fields. Berliner Wasserbetriebe as a statutory company forms the core of the Berlinwasser Group, which was partially privatised in 1999. Land Berlin has a 50.1 percent holding in both the Group and Berliner Wasserbetriebe, and RWE and Veolia each hold 24.95 percent.

The six wastewater treatment plants are equipped with the latest process technology for the biological removal of nutrients. As a result, all treatment plants

observe the limit values for treated wastewater in Berlin and Brandenburg which are much stricter than

Berlinwasser International AG

Discover the world of water – Despite the fact that water is the world’s most abundant natural substance, drinking water is not always readily available. That is why the United Nations’ Millennium Development Goals identified insufficient access to clean drinking water as an obstacle to development for one third of the earth’s population and resolved that this figure is to be reduced by half by 2015. In this context, Berlinwasser International AG delivers clearly defined products and services, essential for sustainable water resources management.

International AG draws on the expertise of the whole Berlinwasser Group, particularly the knowhow gained from decades of experience by Berliner Wasserbetriebe (p. 9).

Berlinwasser International AG is a public limited company active in international water markets as one of Germany’s leading service providers, focussing on the management and operation of drinking water systems and wastewater management systems. The company’s services include the development and implementation of operations, management and contracts, consultancy activities, and collaboration with investors. The portfolio includes concessions as well as BOT and TOT projects, the management of which is the responsibility of the company’s headquarters in Berlin.

Leibniz Institute of Freshwater Ecology and Inland Fisheries

Useful macrophytes for water purification – A system for managing water resources and freshwater ecosystems should be based on a comprehensive combination of disciplinary, interdisciplinary and transdisciplinary strategies, and accordingly the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) is engaged in applied and theoretical research on freshwater ecosystems involving limnology, hydrology, ecology, ecotoxicology, physiology, chemistry, sedimentology and fish ecology. Field investigations of aquatic ecosystems and the impact of catchment areas on water quality are combined with laboratory experiments, data management, modelling and theoretical studies. The research focuses on processes, functions, and the accompanying structures in the aquatic ecosystem, with international projects and also surveys of the lakes and rivers in Berlin and Brandenburg.

Scientists of the IGB are currently working on a project concerned with the purification of water extracted from the lake ChaoHu in the Anhui province in China. Lake ChaoHu is the fifth largest Chinese lake, but because of the high levels of pollution and nutrients in its waters it is affected every year by the mass development of cyanobacteria. The toxins produced by the cyanobacteria, which are also heptatotoxic to humans, reach levels way above the WHO limits for drinking water. Using a relatively simple pond system including

Senate Department for Urban Development

Rain water management and model projects – The demands on buildings are becoming increasingly complex. Planning now not only involves complying with relevant building regulations. It is also necessary to achieve the best possible compromise between a number of sometimes competing goals. The aim is to harmonise planning, construction, and management of a project so that the environment impact is kept as low as possible, natural resources are protected, while results are socially acceptable and

ensure sustainable living and working conditions. The development of standard specifications also has the goal of reducing costs for planning and construction as well as minimising running costs. Projects within the framework of the experimental housing and urban development and the Berlin Urban Ecology Programme focus on topics such as rainwater management and the greening of buildings. A special feature of the model projects is that this «constructional research» is scientifically monitored, evaluated, optimised, and documented. Planning in terms of overall environmental strategies with interconnected individual modules – Energy, Water, Green, Building materials, Waste – has proved to be an important and useful approach for many urban construction projects. In addition to many other questions, the projects also considered the hygienic aspects of the use of rainwater and greywater for non-drinking purposes in buildings. Follow-up scientific evaluations have provided information about the transferability of the results. Recently, the knowledge gained from the model projects could also be used for the development of new process technologies and systems, which have been included in current standards and regulations.

Senate Department for Health, Environment and Consumer Protection

Water management and resource protection – The division of integrative environmental protection of the Berlin Senate Department for Health, Environment and Consumer Protection is responsible, among other things, for representing public interests in water management, water regulation, and geology. Berlin relies on its own water resources to a much greater extent than most other cities of the same size. The entire water supply is extracted within the city limits, and because Berlin’s many lakes and rivers are also used for a variety of other purposes, including goods transport and recreation, it is important to have effective protection and a sustainable water management system.

Besides the specialist responsibilities and tasks, the Water Authority, which is also part of the division of integrative environmental protection, is responsible for issuing permits and formulating related regulations.

At present, the main topics of interest are the implementation of the European Union Water Framework Directive, the challenges to economic viability raised by decreasing water consumption, urban water management, the impact of climate change on water management issues, and the utilisation of geothermal energy. The special demands on the quality of the wastewater treatment plants considerably influence the surface water quality, which is also supervised by the Senate Department. A wide range of measurements are taken relating to geology (more than 800 drillings), hydrology, surface water and groundwater, and the data is analysed and made available to the public.

Senate Department for Economics, Technology and Women’s Issues

Foreign trade and international cooperation – Berlin is raising its profile as a future-oriented business location. The Berlin Senate has established a set of priorities which are reflected in fields of competence such as I Media and communications technology, I Health management, and in particular medical and biotechnology, I Optical technologies, and I Transport and mobility engineering.

In these and other fields of innovation, Berlin aims to establish a prominent position in Europe. The dynamism and modernity of the German capital make it a first choice address for companies in forward-looking sectors. Within the framework of these activities the policy goal is to support the export initiatives of Berlin companies and to promote access to new markets in other countries. A further significant factor for the internationalisation of Berlin is its 17 partnerships with other cities worldwide. The city networks offer an ideal opportunity for mutually beneficial conferences on a variety of relevant urban development topics, such as those that have been organised in recent years by the Berlin Office for Development Cooperation at the Senate Department for Economics, Technology and Women’s Issues (SenWTF). Since 2002, participants from numerous countries have met to discuss topics such as water and wastewater management, waste services, urban planning, environmental protection, and education. A milestone was the International Water Conference Berlin 2004 Urban Waters – Problems and Solutions

18

with regard to Sustainability, attended by more than 80 experts from business, science and research, politics and administration from more than 30 major cities worldwide. In 2005 and 2006, leading water experts from Berlin and Brandenburg met in a series of discussions in order to consider skills and synergies, potentials and future prospects, with a view to strengthening the international involvement of the region. As a result, actors involved in the Berlin water sector have created the Water Plenum as a platform for stimulating future activities. In order to provide coordination, a permanent water plenum working group was set up on the initiative of SenWTF. The next major event is the II. International Water Conference Berlin 2007 Water Problems in Urban Areas and Approaches to Solutions considering the Aspect of Sustainability with leading experts from the AsiaPacific region and from selected Central and Eastern European countries, which will be held within the framework of the Asia-Pacific Weeks from 12 to 14 September 2007. This conference offers Berlin companies an opportunity to establish direct contacts with international water actors in order to coordinate busi-

ness cooperation, establish networks, and access new markets.
