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.

减少非收入水（NRW）是有效管理水资源的最重要策略之一。减少NRW和损失的努力对于规划水务公司的未来预算也至关重要。在本研究中，通过基于趋势的新方法和基于历史数据的风险计算来进行NRW预测。根据特定的风险值对NRW量进行预测，监视和评估，为成功和可持续的水管理提供了客观的规划支持。通过模型图说明特定风险水平与NRW损失金额之间的关系。预计到2023年，特定风险水平下可能会产生北威州损失。北威州预测为预算平衡和合理的水务决策，计划和投资提供了优势。
