Evidence Base

The  Evidence  Base  for  Large-scale  Water  Efficiency helps water companies identify the most effective approaches to water efficiency retrofit programmes, thus fulfilling one of Waterwise’s seven original objectives. 

For a number of years Waterwise has been developing the evidence base. The report for  Phase I drew on evidence from around 20 water efficiency trials and projects in domestic properties that had been undertaken by water companies in the UK; it was  published  in October 2008. Phase II came to a conclusion in April 2011 and contributed to the body of evidence that has been built up in both homes and schools retrofitting. The programme is now mid-way through Phase III.

As part of Phase III of the Evidence Base Programme there have been several changes to the way Waterwise delivers the project. In addition to defining smaller, discrete projects that will be scoped and delivered on an annual basis, there will be more formal peer review built into the project.

In the first year projects were carried which focused on improving uptake in home retrofit programmes,scoping water efficiency education activities in schools and customer feecback to water efficiency retrofit devices (to be published soon). The second year projects are underway and focus on examining piggybacking initiatives as well as developing an evaluation tool kit.
