The present thesis gives an overview on technical problems with the water supply systems of the Al Koura district in northern Jordan. The initial goal was to work out improvements for the complete area - besides the Geographic Information System (GIS) that was created, however, this approach was abandoned due to time constraints.
Instead the paper focuses now on a fundamental problem: The representation of intermittent supply in simulation models of water distribution networks. Intermittent supply is heavily disadvantageous for a number of reasons. Yet it prevails the dominant supply scheme in most of the developing countries throughout the world.
The fact that the majority of the world's population is supplied in this way is already stunning. What is even more astonishing is the fact that there are virtually no applicable simulation models for the intermittent supply of water. Reliable simulation models are a factor for the optimization of water distribution - they enable modern water undertakings to serve their customers around the clock, seven days a week.
This thesis describes the development of a practical simulation model for the intermittent supply of water. Standard software is used to implement the model: ESRI's ArcView GIS and the free hydraulic analysis software EPANET. The model has been applied to the water supply network of the village Judayta and successfully calibrated with a logging campaign.
