In this report Waterwise examines the effectiveness of water efficiency retrofitting programmes in schools in three English regions and Scotland. Its aim was to demonstrate the benefits, from both the water company and schools perspective, and to inform future water company activity. It draws on data from about 600 schools, four water companies and five water company school retrofitting programmes. The study suggests achievable water savings between 0.58 and 1.78 m3/pupil/year, as well as significant carbon emissions and energy savings. Costs amounted to £0.41 to £0.72 litre/day, which compares to the cost of water savings achievable through domestic retrofits.
