Water suppliers can be treated as production companies whose main product is water delivered to their customers. The article presents problems connected with management of such companies under conditions of secondary pollution in water distribution systems. This phenomenon exist in water networks all over the world. Its’ presence is particularly visible in the countries of former Communist Bloc. In Poland decrease in water consumption has been observed since 1989 after political transformation. Average water consumption per capita fell from over the 230 to about 100 dm3/d. As a result all existing networks began to work in conditions of severe oversizing. So retention time (water age) in water networks increased significantly, with all its negative consequences – sedimentation, deterioration of transferred water quality. Particular attention was devoted to the issue of water quality correction in the analysed systems. Quality correction is recognised as one of key activities in the process of production company management. In the case of water distribution systems, former quality correction methods consisted in special treatment of water pumped into the system, flushing and cleaning of water pipes. In both these cases identification of water quality deficiencies resulted in significant water loss. The situation reflects management processes applied in the manufacturing industry of the 1940s. The authors of this paper put forward the concept of four water quality correction methods which would not entail such considerable water loss. The methods in question are intended for different network types. The implementation of proposed solutions could set new standards in management of distribution systems of water providers.
