Short summary
The article introduces a stable formulation of the model for water distribution systems that guarantees the existence of a unique solution. This is done regarding two modeling paradigms. First for models with customer demand as a fixed boundary condition and second for models that add a boundary condition on the minimum network pressure. The following discussion concludes that pressure-driven models are superior in modeling deficient networks, but still have to be improved.
