摘要：This paper aims to highlight some of the main issues raised by developing and implementing the most appropriate approach to water pricing, and to induce a sustainable water management. Therefore, we define the concept and utility of water demand management as one objective of efficient water pricing. Next we analyse the basic economics and some important theoretical insights of water pricing. We further with state the main four inter-correlated principles of sustainable water pricing (full-cost recovery, economic efficiency, equity and administrative feasability) and the trends and challenges of their actual implementing in the water pricing policy of Romania and other EU countries. We end with a review of opinions, personal conclusions and recommendations on the actual opportunity, effectiveness and role of efficient water pricing in fulfilling the goals of sustainabilty.
