Utilization of online water quality measurements to ensure safe drinking water

Ensuring safe drinking water for all is one of the sustainable development goals. Online water quality monitoring in drinking water distribution systems can be used to control risks of water contamination. A case in point is wastewater intrusion from a nearby leaking wastewater pipe to a ruptured drinking water pipe. Water quality can be online monitored via conventional water quality parameters, such as turbidity, conductivity, or chlorine concentration. However, new types of sensors are constantly being developed. This doctoral thesis studies the new applications for conventional online water quality sensors in water quality monitoring of drinking water distribution systems. In addition, the capability of novel sensors is determined in terms of distinguishing actual contaminations from normal water quality fluctuations in drinking water distribution systems.
