Abstract Summary
According to Dutch legislation the drinking water temperature should be lower than 25°C at the tap to meet legionella prevention. In order to assess the impact of heat sources like heat transport pipes on the temperature in adjacent drinking water pipelines a soil temperature model was developed. This coupled micro-climate and heat transport model relates atmospheric conditions to the temperature distribution in the sub-surface. The model is validated by a number of field tests in the Dutch city district Kralingen. The validated model is used here to predict the drinking water temperature in transport, primary and secondary networks.
