Influence of Non-Revenue Water (NRW) on the Sustainability of Water Supply in Selangor, Malaysia

Abstract

Selangor is the most developed and one of the richest states in Malaysia as well as the largest contributor to the country’s gross domestic product (GDP). This situation influences the demand for water. To ensure a constant supply, conducive situation in terms of weather, infrastructures and efficient management are needed. Non Revenue Water (NRW) remained above 30% in 2012 and global warming are some of the major challenges to the sustainability of water supply in the state. Total rainfall and surface water flow in Selangor is expected to decrease due to the effects of the dry spells. This decrease will have negative effects on the social and economic development of Selangor. This study analyzes the influence of NRW on the sustainability of water supply in Selangor in order to meet the increasing demand especially in the dry spell periods or drought season.
