Abstract:
Presented herein is a methodology for evaluation of water losses based on discrimination of the two components of uncontrolled water in a water distribution network: physical losses in mains and service connections, and the volume of water consumed but not measured by meters. The water balance calculations consider that all nonmeasured consumption is uncontrolled water and consequently an apparent loss. The methodology is applicable to an entire network or portions thereof, and presumes that real losses in certain physical states of a network are a function of pressure, while apparent losses (defined as nonmetered consumed water) are a function of consumption patterns (i.e., domestic, industrial, institutional, etc.). An extended period simulation of a water distribution network is employed to accurately determine both terms.
