As part of a tool to minimize sediment caused drinking water quality problems, a model for the transport behavior of sediments, i. e. mainly corrosion products, in drinking water distribution systems was developed. A pilot plant consisting of two pipe loop systems of polyvinyl chloride (PVC) and steel with 80 mm inner diameter and 200 m of length each was developed and constructed. First, experiments with model particles suspended in drinking water were performed. The observed transport behavior of the used particles showed no satisfying compliance with existing models for transport of sediments which were mainly developed for application in sewer systems and rivers. This is attributed to different conditions. Further experimental and theoretical investigations will be carried out in the future. Includes 8 references, table, figures.
