The water and wastewater pipe net management is of considerable interest. The management influences risk for distribution interruption, health disruptions and environmental safe sewer discharge. There are also huge values involved. The renewal of the pipe networks is the major question, each municipality has to handle. There is a lot of knowledge among the water administrations in the municipalities; however the knowledge is often in the mind of the employees. Water engineers in 18 Swedish municipalities of various categories have been interviewed. Most municipalities are in short of a systematic renewal planning, such as risk analysis or cost calculated goals. The interviewed municipalities felt that there renewal rate should be higher, but they have no structural instrument to show the reasons. Priorities were done as “worst first”, and the selection of “worst” were built on experience. There is a need of structure in order to assist the municipalities to rely on their work, and to express to politicians and others the future rehabilitation needs.
