One of the best ways of doing this is to model current water use and then test options to reduce water use in the model to decide on the best option(s) to implement to achieve required reductions. This enables non-cost interventions related to behavior (such as shorter showers) to be implemented before incurring the significant expense and disruption associated with major water system upgrading.

The Water Use Modelling (WUM) tool and course developed by Gauge support rapid modeling of water systems in buildings in order to inform water use reduction strategies.The course provides insight into how water use in buildings can be modeled. It includes a simple water modeling tool in Excel which can be populated with information from an existing building or a proposed building to produce reports of predicted water use in relation to targets.
