Analysis of Relations Between Pressure and Water Age in Water Distribution Systems

This Paper focuses on the relationships between pressure and water age. At first basic water distribution network principles are used to drive mathematical relationships. Then through EPANET examples the derived mathematical relations are investigated by using three EPANET water network models as case studies to validate the relationships between pressure and water age. Combined with the model analysis, we conclude that, water age and water leakage can be indirectly controlled through appropriate localization of pressure reducing valves (PRVs).
