Abstract

Reducing non-revenue water (NRW) is one of the most significant strategies for the effective management of water resources. Efforts to reduce NRW and losses are also critical for planning the future budgets of water utilities. In this study, NRW prediction are made by a new approach based on trend and risk calculations based on historical data. Prediction, monitoring, and evaluation of NRW amounts according to specific risk values provide objective planning support for successful and sustainable water management. The relationship between specific risk levels and NRW loss amounts is explained through the model charts. Possible NRW losses for specific risk levels are predicted through 2023. NRW prediction provides advantages for budget balances and sound water utility decision-making, planning, and investment.
