This report summarises the project and presents the findings from Anglian Water’s Ipswich Water Efficiency trial. Householders were offered a free water audit together with the supply and fitting of free water saving devices as appropriate to their houses. Water-saving devices were installed in 552 properties and behaviour change measures were applied in another 47 properties. Households reduced water consumption by 41.5 litres/property/day, equating to 14.2% of their total demand. These were largely achieved through retrofitting toilets with a dual flush device and using shower flow regulators or replacement showerheads.
