The ARC partners will cooperate in the EU FP7 project TRUST (Transitions to the Urban water Services of Tomorrow). The project aims to develop a range of new methodologies and associated metrics, tools and techniques to help water authorities and utilities formulate and implement appropriate urban water policies. These will cover the full water cycle with regard to cost-effectiveness, performance, safety and sustainability under changing and challenging conditions in Europe. The project brings together 31 international partners led by the IWW Rheinisch-Westfaelisches Institut fuer Wasser in Germany. The TRUST project started in May 2011 and will last for a period of 4 years. For more information, see the TRUST-website: www.trust-i.net.
