NON-REVENUE WATER: IDENTIFYING CHALLENGES AND ANTICIPATING FUTURE SOLUTIONS

Abstract

Water, a vital resource for human survival and societal development, is increasingly threatened by the pervasive issue of Non-Revenue Water (NRW). This paper explores the multifaceted challenges associated with NRW, investigating the technical intricacies, economic implications, and social dimensions that contribute to water losses globally. Aging infrastructure, technical inefficiencies, and varying socio-economic factors are identified as primary challenges impacting the management of water distribution systems. The economic toll of NRW is analyzed, revealing substantial financial losses for water utilities, hindering their ability to invest in critical infrastructure upgrades. Social justice aspects of NRW are unveiled, emphasizing how unequal access to water services perpetuates disparities, particularly in vulnerable communities. Climate change further amplifies the complexity, introducing new challenges to water availability and distribution. Community engagement strategies and adaptive measures in the face of climate change are also investigated. By comprehensively understanding the challenges and proactively seeking solutions, stakeholders can pave the way for sustainable, resilient, and equitable water management systems. This paper serves as a valuable resource that discuss in general Europe, China, Japan, South Korea and specifically in specific states Malaysia regarding NRW systems.
