For accurate prediction of energy production in a detailed planning process, a long-time evaluation of the
performance would hence be more reliable. In WDS modelling a representative demand pattern is usually used for
these assessments. Only [4] used a long time simulation for a water distribution model for water quality simulations
and gained valuable insight in that behavior based on multiyear simulations. In this work, an hourly measured water
consumption data of a water distribution system over one decade is used as input for an Epanet2 long-time simulation
model [5].
