Non-revenue water new paradigm for planning and management by performance indicators

Abstract

Abstract Water service providers often face challenges when assessing their Non-Revenue Water (NRW) performance, which prompts them to set ambitious targets and adjust their NRW management plans. NRW planning and management involves a comprehensive approach that incorporating technical, managerial, and behavioral strategies. Insufficient NRW reduction efforts globally can be attributed to a lack of understanding the magnitude, origins, and expenses associated with NRW. Water decision-makers and staff often lack the capacity to identify the underlying causes of NRW. To address this, a new approach called the Planning and Management by Performance Indicators (PMPI) model has been developed, with a focus on reducing NRW. The PMPI model provides with a standardized and quantifiable way to evaluate NRW management performance. Comparing indicators over time, utilities can assess the effectiveness of their interventions, identify trends, and make necessary adjustments. A systematic literature review and expert consultations were conducted to develop this methodology. The ultimate goal of the study is to create a new PMPI tool for analyzing, planning, managing, implementing, and monitoring NRW. The conceptual model for PMPI of NRW was evaluated by academics and professional experts, resulting in an overall assessment of 80.0 percent. The majority of aspects were found to be well and highly validated. The PMPI approach adopts a linear sequential process, involving extensive performance indicators analysis, setting targets, creating action plans, and making continuous adjustments based on monitoring and feedback from stakeholders. To ensure a comprehensive and effective NRW approach, the model incorporates the IWA water balance dimensions and main components.
