Water efficiency remained constant at 7.6L/TRh. 7.6L/TRh water efficiency Annual Report 2019 There is no improving frontier performance on this measure, that is to say the best performing 6.5 plant are not making year on year improvements, with performance hovering around 6L/TRh. Total supply of recycled water remained constant at 5,000 megalitres but, with the addition of new plant yet to be connected to the recycled water network, the proportion of water demand met by recycled water dropped by 2% to 24%. Losses, measured as the difference between sales and production, were 9%, up from 6% in 2018. Increased losses occurred at three of the DC providers. Unit prices rose to AED1.18/TRh driven by the lower demand per square meter of floor space. We also estimated what a typical customer with average demand occupying a unit of 200m2 would expect to pay in cooling charges for the year. In 2019 this estimated typical bill fell by 8.1%, which reflects the lower cooling load density offered in new DC schemes and lower consumption. 7 6 5.5 5 4.5 supply of recycled water 9% Increased losses ML RSB 17
