ABSTRACT
Understanding the reasons for water quality failures in drinking water distribution systems has become a priority for network managers. The proposed approach provides a unique tool for assessing the consequences of water supply changes and the consequences of distribution system operation and maintenance on the quality of distributed water. Its main benefit is to help the water producer understand the origins of local water quality problems, and consequently to eliminate them from their distribution system.
