Abstract. Primary goal of a drinking water company is to produce safe drinking water fulfilling the quality standards defined by national and international guidelines. To ensure the produced drinking water meets the quality standards, sampling of the drinking water is carried out on a regular (almost daily) basis. It is the dilemma that the operator wishes to have a high probability of detecting a bias while minimizing his measuring effort. In this paper a seven step design methodology is described on how to come to an optimized water quality monitoring scheme. It was shown that the existing on-line monitoring program of a WTP could be optimized. Besides using soft-sensors as surrogate sensors for parameters currently not available on-line, they can also provide a cost effective alternative when used to determine multiple parameters required through one single instrument.

Short summary
In this paper it was shown which water quality information is required to be measured on-line to ensure the production of good quality drinking water. This was determined by following a seven step approach, which helped to understand the processes taking place as well as the dynamics. It was shown that the use of a single instrument able to measure different parameters can be of benefit.
