This report brings together findings from a trial carried out by United Utilities in 2006-2007 that investigated the effectiveness of water-efficient devices. 4,642 domestic properties in Warrington were sent an invitation. 393 took part in the audit and received a ‘water savers pack’, which included a basic shower timer and information on saving water. Further devices were installed where appropriate including water efficient showerheads, dual flush retrofit and save-a-flush cistern displacement devices. 67 % of 211 measured households were able to save water, on average 20.6 litres per property per day, which represents a reduction in water use of 6.8%.
