Keywords: water utility | performance indicators | IWA Best practice

Active water loss management has become one of the primary interests of the water utilities in the world. Due to efforts of the IWA Task Force in the last decade, traditional approach of water loss expression in percentage of system input values has been proven to be misleading in may cases, and new way of performance measuring and benchmarking is proposed. This paper presents the basic principles of this methodology and results of the first step in attempt to approach Serbian water utilities performance according to new standards. Pirot water supply system is used as a case study to estimate pressure reducing impact on technical performance indictor values before introducing active leakage control.
