ABSTRACT

Drinking water quality leaving water treatment works is known to deteriorate as it makes its way through distribution networks. As deterioration rates are related to the condition of the network and how it is operated, it is important to determine the location and magnitude so that causes can be determined and effective maintenance implemented. Water quality is typically monitored at outlets of service reservoirs to help track changing water quality. However, these results do not confirm whether the issue is linked to the network between treatment and the service reservoir, the service reservoir itself, or both. The work in this paper investigates the value of using inlet monitoring at service reservoirs to overcome this limitation. Results show that monitoring at both the inlet and outlet of service reservoirs provides valuable information on asset performance and highlights the location and extent of deterioration helping inform cost-efficient resource provision.

摘要

众所周知，离开水处理厂的饮用水水质会通过分配网络而恶化。由于劣化率与网络状况及其运行方式有关，因此确定位置和大小非常重要，这样才能确定原因并进行有效维护。通常在服务水库的出口处监测水质，以帮助跟踪变化的水质。但是，这些结果不能确定问题是否与治疗和服务储库之间的网络，服务储库本身或两者都有联系。本文的工作研究了在服务水库中使用入口监控来克服此限制的价值。
