They found three groupings with distinct patterns of use focussed on the peak morning usage. These were identified as use 6.00-8.00), “early risers” (peak and (10.00-12.00).

Again, as the authors highlight this is a small sample size but what it provides is a possible way of looking at patterns of use. Figure : Grouped bar chart of PCC by micro-component, for the three groups (UKWIR, 2016) In the final part of the project they link the patterns of use with household and property types as they had survey data for the properties that had their consumption monitored. In effect they bring together individual, social and material data to describe the three consumption groups. What they explore is the extent to which it might be possible to predict membership of one of the types of use groups solely from survey data, which if possible would give a way of water companies targeting water efficiency interventions. Table 13 provides a summary of that information together with suggested approaches to targeting water efficiency campaigns. No information was available in the literature reviewed about the application of these approaches in practice.
