Water Loss Reduction in Water Supply Systems

Water loss in water supply systems is a serious problem for almost all urban areas around the world and it can be even worse in areas with scarcity of water. This problem deserves immediate attention and appropriate action to reduce avoidable stress on scarce and valuable water resources. Several big cities have already started programmes geared towards the step-by-step reduction of the losses and it is well known that many institutions and water and sanitation utilities have developed and implemented strategies and technologies to control leakage and water loss. These strategies have proven highly efficient and received worldwide recognition.

The conference will be held for tenth time and is considered to be major annual water loss event in the Balkan region.

This year’s conference will document available know-how and best practices and will recommend new approaches for more efficient management in the field of water with a focus on water loss reduction. National Partners of BWA are the Union of WSS Operators in the Republic of Bulgaria as the biggest branch organisation of water utilities in Bulgaria that supports the development and professional qualification of all employees in water sector among other activities as well as the Bulgarian WSS Holding founded to support in any way the work of Bulgarian WSS utilities. More information about the structures could be found on the website International Partner is European Water Resources Association (EWRA) which is a leading European non-profit organisation aiming at the enhancement of cooperation and the exchanges in application and research on all aspects of water resources. Further information regarding the activities of the organisation could be found at its website:
