Water Board of Lemesos
Water Losses are made up of the Apparent and Real Losses. The Water Board of Lemesos considers that the reduction of Apparent Losses is as equally important as the reduction of Real Losses. This paper provides a detailed account of two studies that were carried out at the Water Board of Lemesos in order to quantify meter under-registration caused by the use of ball valves in customer roof tanks and the results obtained and conclusions reached are presented and discussed. The first study aimed at proving beyond any reasonable doubt that the ball valves used in customer roof tanks result in meter under-registration especially at the very low flows. The second study involved the testing of a flow manipulation device which would assist in the reduction of the un measured flow through the customers’ meters at low flows.
