The operation of the present-day infrastructure is done by operators that mainly focus on providing the required flow at all times. It is obvious that it is possible to achieve better results at lower costs and with less impact on the environment by utilising available options such as buffer tanks, equal flow distribution over filters, flow control and process control. By using computer models it is now also possible to improve the water quality leaving the treatment plant while delivering the required flow. Focus of this theme is on an optimised process and flow control by mass balance based modeling and by more sophisticated computational fluid dynamics. Also stochastic data models are used to assess the efficiency of treatment processes. We aim to achieve the concept of a ‘virtual treatment plant’, that is a model of the plant that can function as a simulator to assist the operator in finding the optimal settings.

Theme 4: Optimal design and operation of distribution networks After water is treated to drinking water it is transported to the customers in large underground distribution systems. In the distribution systems the water quality deteriorates in time due to several complex interrelated processes. The objective of this research theme is to understand the water quality processes in the distribution network, to develop new (on-line) tools to assess the water quality in the distribution system and to propose innovations and guidelines to prevent future water quality deterioration. Focus will be on the effect of natural organic matter (NOM), the hydraulic behaviour of sediment in the distribution system, the chemical interaction between water and the piping material, the design of self cleaning networks and the prediction of .

The current knowledge on low-cost drinking water treatment is often insufficient to provide safe water in remote and underdeveloped areas. Either solutions do not fit within the targeted environment or a scientific approach is not at hand. Research to develop and improve treatment systems for the poor is the main objective of the work done within this new research theme. The (upcoming) projects in this theme aim at critically evaluating existing treatment options and the development of new innovative technologies. The current research focuses on low-cost ceramic filtration, subsurface arsenic removal, and utilization of renewable energy.
