The World Health Organization (WHO) has recommended Water Safety Plans (WSPs) since 2004 as a means to reduce drinking water contamination and risks to human health. These risk management programs have shown promise across several potential areas of evaluation, such as economic benefits and regulatory compliance. Since WSPs are largely carried out by people who interact with water treatment equipment and processes, operational performance indicators may be key to understanding the mechanisms behind desirable WSP impacts such as water quality and public health improvement.
This study reports performance measures collected at a WSP implementation location in southwestern France over several years.
Quantitative assessment of performance measures supported qualitative reports from utility managers. Results indicate significantly reduced duration of low-chlorine events at one production facility and a significant decrease in customer complaints related to water quality, manifesting reported improvements in operational performance and the customer service culture.
The findings demonstrate some success stories and potential areas of future performance tracking. Cyclical iteration of the WSP can help to achieve continuous quality improvement. Successfully applied evaluation criteria such as the number of water quality complaints or alarm resolution time might be useful across other locations.
世界卫生组织（WHO）自 2004 年以来一直推荐水安全计划（WSP），作为减少饮用水污染和对人类健康风险的一种手段。这些风险管理计划在多个潜在的评估领域显示出了前景，例如经济效益和法规遵从性。由于 WSP 主要由与水处理设备和工艺相互作用的人员执行，因此运营绩效指标可能是理解 WSP 影响背后机制的关键，例如水质和公共卫生改善。
本研究报告了在法国西南部的一个 WSP 实施地点多年来收集的绩效指标。
对绩效指标的定量评估支持了公用事业经理的定性报告。结果表明，一个生产设施的低氯事件持续时间明显缩短，与水质相关的客户投诉显著减少，表明运营绩效和客户服务文化的改善得到了体现。
研究结果展示了一些成功案例和未来绩效跟踪的潜在领域。WSP 的周期性迭代有助于实现持续的质量改进。成功应用的评估标准，例如水质投诉的数量或报警解决时间，可能在其他地点也有用。
