policies, data, and reports connected to water in the EU. The target group of this online information system is researchers and professionals dealing with water related issues within the framework of the EU. The platform helps to store and administer data and output handed in by member states and agencies connected to the reporting requirements of the European Commission. EAP Task Force The Environmental Action Programme (EAP) is a policy adopted by Environment Ministers in 1993 in a conference in Switzerland. An international Task Force was established later on to support mainly states of countries in the Eastern Europe, Caucasus and Central Asia. In WSS they are supporting the financial strategies of a number of countries to achieve the Millennium Development Goals. Furthermore, they are working on indicators and monitoring systems in those countries to collect data of water utilities to check their performance. Apart from that, the EAP task force is figuring out the potentials of the private sector to participate in the water sector especially in water supply and sanitation in the EECCA countries and they consult local partners in financial planning and investment. They are also collaborating with the EU Water Initiative since 2005. Major challenges Major challenges of the EU concerning WSS are connected with modern pressures to the system. Climate change, demographic developments, urbanization, economic progress, social changes influence the water sector in many ways. The European Union is said to be very effective concerning water management and policies. However, especially the new member states located in Eastern Europe are in need of enormous investments to ensure the sustainability of the water infrastructure. The existing and foreseen problems are the lack of investments in the rural and municipal water supply which led to poor services (e.g. water leakages, interruption of service, insufficient water availability during drought, etc.), the limited availability of water resources and its energy consumption which can represent up to 50% of municipalities' electricity bill. Technologies are actually available and with a quick return on investment but the sole focus on water quality has diverted the attention for the increasing need of sustainability from the water sector in the context of climate change. Water supply limitation counts as major concern. The first and most rational answer should be to tackle the water leakage problem Europe is facing as almost 1/4 of treated water is leaked in average in the EU. Moreover, research shows
