1 Arbeitsgemeinschaft Trinkwassertalsperren e.v. TT Profile of the German Water Sector 2015 Summary
2 Foreword 02 With the the ATT, BDEW, DVGW, DBVW, DWA and VKU in consultation with the German Association of Cities (Deutscher Städtetag DST) and the German Association of Towns and Municipalities (Deutscher Städte- und Gemeindebund DStGB) provide an up-to-date picture of water supply and wastewater disposal in Germany. It gives the interested public and decision makers extensive, detailed information about the water sector s performance, the great variety of its tasks and the current challenges it faces. Like the previous three editions since 2005, the fully up-dated Profile 2015 demonstrates that the modernisation strategy pursued equally by the government and by the water sector itself is also taking effect in an increasingly difficult environment. The Profile documents the high performance of the German water sector in European and international comparison with regard to safety, quality and sustainability of the supply and disposal services, economic efficiency and customer satisfaction. It is essential to maintain the level of performance achieved to date and to bring about improvements wherever possible and required. The associations promote the continuous improvement process in the companies through benchmarking and recommend their members participate in benchmarking projects (Associations Declarations 2003 and 2005). Benchmarking means to compare and improve by learning from the other participants in a comparison group. Benchmarking, the transparent documentation of performance through the water sector s Profile, and continuous development are the pillars of the sector s permanent improvement which it implements in its own responsibility. This concept was acknowledged and supported by the German Federal Government in its 2006 report on the modernisation strategy for the German water sector.

3 Core statements Performance In Germany the citizens always have drinking water available in excellent quality and sufficient quantity. In addition to the comfortable resource situation in Germany as a water-rich country, the high technical standards and a range of voluntary measures by the water sector contribute to the protection of natural resources. Water utilisation in Germany in 2010 Total available water resources: 188 billion cubic metres Data as percent 14.9 % 2.7 % Non-public water supply 28 billion m³ Public water supply 5.1 billion m³ Unused billion m³ % Source: German Federal Statistical Office, Fachserie 19, Reihe 2.1.1, published in 02/2013; German Federal Institute of Hydrology Wastewater treatment in Germany is also at a very high level. In contrast to many EU countries, almost 100 percent of the wastewater is treated to the highest EU purification standard. Through their work, drinking water suppliers and wastewater utilities thus contribute significantly to preventive and comprehensive water resources protection. Performance characteristics of the water supply and wastewater disposal in Germany are long-term safety of supply and disposal, high drinking water quality, high wastewater disposal standards, high customer satisfaction and careful management of water resources and economic efficiency. These aspects are considered in the 5-pillar benchmarking concept. Through the nationwide application of benchmarking, the utilities have significantly improved in all service areas.

Benchmarking projects are a key instrument here. The main prerequisites for the success of the benchmarking and performance indicator projects are confidentiality and voluntariness, but also the consistency and compatibility of data. For this purpose, the performance indicator systems of the industry are continually developed. Approved technical standards and adherence to strict legal requirements lead to the high quality and the long-term safety of the German drinking water supply and wastewater disposal. Organisation and efficiency In Germany, water supply and wastewater disposal are core duties of public services in the general interest within the competence of the municipalities or other public corporations. Their democratically legitimised bodies take the strategic decisions with regard to the forms of organisation, participations and cooperation. Germany has a varied supply and disposal structure comprising public and private sector companies.

6 Fees, drinking water quality, environmental requirements as well as water abstraction rights and discharge rights are subject to strict state control; the cost coverage is anchored in law. The increase in fees for drinking water and wastewater have mainly been below the inflation index for many years. Safety of supply and drinking water quality are of utmost importance for the customers and almost all consider the fees paid for this to be appropriate. The specific regional and local parameters determine the supply and disposal conditions on site. Water supply and wastewater disposal therefore always require locally adapted solutions. This, combined with the different legal requirements of the federal states, results in different efforts and costs. Taking into account the respective water consumption and performance standards, customers in Germany spend less on their drinking water than customers in comparable European countries.

Therefore, they have continually invested in the education of young people for many years, often beyond their own needs.

8 Tasks and challenges The requirements put on modern, sustainable water management are increasing steadily. It s no longer just a matter of providing drinking water and treating wastewater. The comprehensive approach is increasingly gaining in importance, with the aim of achieving a sustainable, integrated water management. Thus, in addition to drinking water supply and wastewater disposal, among other things, the maintenance and protection of water bodies, the landscape water regime and coastal protection and flood control are among the tasks of a functioning water sector. In addition, the changes in social priorities influence the work of the water sector. Thus, energy consumption and efficiency, and resource protection are becoming increasingly high profile. Concomitant conflicts of use with the water sector need to be solved through social consensus. In addition to proven methods, the utilities develop and test new technologies to save or generate energy. This includes, for example, the use of energyefficient pumping technologies or heat recovery from wastewater. Operators make great efforts to treat wastewater with a minimum expenditure of energy. In wastewater disposal, a quarter of the total power consumption of 4.2 twh per year is already covered by the utilities own energy production in the context of sludge digestion. As a result of our modern industrial society and sophisticated analytics, anthropogenic micro pollutants can be detected better in groundwater and surface water. There is considerable need for research on their effects on humans and the environment. This challenge cannot be dealt with solely by the water sector. When dealing with micro pollutants, the focus needs to be on preventing their input at the immediate source. Where this is not possible, the polluter pays principle needs to be applied. 08 Share of the plants' own energy generation as percent 29 % external energy procurement own energy generation 71 % Source: VKU, Energie im Fokus, 2012
9 Water consumption has been decreasing significantly for decades. Nevertheless, the utilities have to provide appropriate capacity for peak demand and an infrastructure which is able to cope with this. Therefore, political demands for further reductions in water consumption are not reasonable, especially in water-rich Germany. Development of the per-capita water consumption Data in litres per person and day, Germany Source: German Federal Statistical Office, Fachserie 19, Reihe 2.1, Heft 2010, published in 08/2013 Demographic and climate change together with continuously decreasing water consumption pose great challenges for the German water sector. The German water sector meets these challenges by developing solutions that are adapted to the respective conditions. It proves that it can meet these challenges thanks to its comprehensive technical, economic and scientific expertise and its practical research activities. Demographic change, the looming climate change, the sophisticated detection and the minimisation of the input of anthropogenic micro pollutants, as well as conflicts of use with industry, agriculture and energy policy objectives are the current challenges faced by the German water sector. Drinking water supply and wastewater disposal face these tasks and work locally to achieve flexible and adapted solutions that comply with the social consensus.
10 Statewide benchmarking projects in water supply and wastewater disposal To remain competitive, the water sector needs to be efficient, economically viable and transparent to the customer. Benchmarking projects are a key tool here so that the sector continues to develop steadily and dynamically. Therefore, the associations of the water sector have supported the various benchmarking projects commissioned by the economics, interior and environment ministries of Distribution of statewide water supply benchmarking projects 10 North Rhine- Westphalia 86 % Rhineland- Palatinate 67 % Saarland Bremen 100 % Hesse 42 % Schleswig- Holstein 28 % Hamburg 100 % Lower Saxony 81 % Saxony- Anhalt 64 % Thuringia 63 % 92 % Bavaria Baden- 60 % Württemberg 66 % Mecklenburg-West Pomerania 80 % Berlin 100 % Brandenburg 95 % Saxony 71 % xx % share of drinking water quantities covered by benchmarking projects (cumulative value) with public project report without public project report Source: Public project reports and BDEW 2014
