This reports analyses a water effiiciency project trialled by the Environmental Agency and several water companies to further knowledge on the suitability of retrofit devices for demand management programmes. Two devices – Ecoflush and Variflush – were installed in domestic properties. The project used water consumption data gathered from 136 properties and feedback collected from 271 customers. In the weeks after the devices were installed, water demand fell by an average of 8.5% per property. Reductions were insignificant between the two devices, yet varied strongly between the different properties.
