Water Loss Detection System of Malang Water Supply System

Abstract

The implementation of the Drinking Water Supply System by PDAM is responsible for providing drinking water services to the community. Losses incurred due to water loss include being unable to meet drinking water needs, reduced revenues, increased operational costs and worsening infrastructure. One of the concrete efforts of PDAM management is to control the level of water loss. Water loss is defined as the difference between production volume and collectible water volume based on customer meter. Data analysis for water loss control is done by identifying the existing PDAM conditions related to Non Revenue Water (NRW) level issues and efforts that have been made to address them. Identification of PDAM existing conditions begins with identifying the service area as a whole through an existing network map. Then the identification of existing conditions of PDAM through existing water balance data. Water balance data is available for each component of the water balance so that existing conditions are obtained for each existing component for both commercial water loss, physical water loss, and NRW level. Asset management and technology can also play a role in water loss control analysis. Currently the use of SCADA technology in water loss control is able to monitor, control, and acquire data on a particular process continuously.
