The objective of this study is to assess the risk of insufficient water supply posed by high-turbidity water. Several phenomena can pose risks to the sufficiency of a water supply; this study concerns risks to water treatment plants from particular properties of rainfall and raw water turbidity. High-turbidity water can impede water treatment plant operations; rainfall properties can influence the degree of soil erosion. Thus, water turbidity relates to rainfall characteristics. Exceedance probabilities are presented for different rainfall intensities and turbidities of water. When the turbidity of raw water is higher than 5,000 NTU, it can cause operational problems for a water treatment plant. Calculations show that the turbidity of raw water at the Ban-Sin water treatment plant will be higher than 5,000 NTU if the rainfall intensity is larger than 165 mm/day. The exceedance probability of high turbidity (turbidity >5,000 NTU) in the Ban-Sin water treatment plant is larger than 10%. When any water treatment plant cannot work regularly, its ability to supply water to its customers is at risk.
本研究旨在评估高浊度水对供水不足的风险。有几种现象可能会对供水的充足性造成风险；本研究关注的是降雨特性和原水浊度对水处理厂的风险。高浊度水会阻碍水处理厂的运行；降雨特性会影响土壤侵蚀程度。因此，水的浊度与降雨特征有关。本文给出了不同降雨强度和水浊度的超越概率。当原水浊度高于 5000 NTU 时，会给水处理厂的运行带来问题。计算表明，如果降雨强度大于 165 毫米/天，班辛水处理厂的原水浊度将高于 5000 NTU。班辛水处理厂高浊度（浊度大于 5000 NTU）的超越概率大于 10%。当任何一个水处理厂不能正常工作时，其向客户供水的能力就会受到威胁。
