Rehabilitation of water distribution facilities - the holistic approach of the German DVGW standards

摘要

The DVGW technical standards demand a long-term, optimal rehabilitation of water distribution facilities to ensure a high level of supply quality and network condition, as well as a low risk potential and lowest possible total costs. Bernd Heyen discusses the example of German water and gas utility GELSENWASSER, whose interconnected water distribution network proves that not only the requirements, but also the procedure, are compatible with practical experience.
