这项研究评估了从处理厂成品水到泰国曼谷的消费点的化学和细菌水质恶化， 配水系统，并着重于输水的作用 主管和延伸分配系统（房屋管道）对水质的影响 恶化。样本以广泛的空间和时间模式收集，以检查 水质恶化（物理、化学和微生物水质） 曼谷都市区的变化。 地点包括在不同的前提下 类型（学校、住宅、医院、商业）、房屋管道设计（仓库、湿火） 系统，过滤或未过滤）和用水模式（高/低需求，白天/晚上） 需求）。进行统计分析，以发现是否存在显著的预测因素 这些系统内的水质恶化。工程的有效性 干预措施将在成功识别污染/再生后进行评估 消息来源。

This research evaluates the chemical and bacteriological water quality deterioration from treatment plant finished water to the point of consumption in the Bangkok, Thailand, water distribution system, and focused on the role of water transmission mains and extension distribution systems (premise plumbing) on water quality deteriorations. Samples were collected with an extensively spatial and temporal pattern to examine the water quality deteriorations (physical, chemical and microbiological water quality changes) in the Bangkok metropolitan area. Locations were included with various premise types (school, residential, hospital, business), premise plumbing design (storage, wet fire system, and filtered or unfiltered) and water use patterns (high/low demand, day/night demand). Statistical analysis was conducted to find if significant predictors exist for water quality deteriorations within these systems. The effectiveness of engineering interventions would be evaluated upon successful identification of contamination/regrowth sources.
