A methodology is developed to reveal the dynamics of behavior and interactions among actors (stakeholders) in water supply systems and their effect on the technical network and the ecological and socio-economic environment. An agent-based model is under construction which allows to simulate different scenarios of the actors' behavior and to compare the results with observed phenomena (stylized facts) of Swiss cities. First results further clarify the significance of demand trend analysis. We envision the model in a final stage as being helpful to tackle the task of illuminating the diffusive claims, expectations and interactions of the actors involved. Knowledge about these processes is crucial to uncover bottlenecks hindering the sustainable development of our water supply systems into the future.

AbstractIn the aspect of water management, the Water Directive regulates water management with the principle of sustainable development, in shaping, protecting, using and managing water resources. Analysis and assessment of the CWSS safety is a complex issue, including the analysis of potential threats, their effects and safety systems (barriers). The analysis is performed in terms of the water consumers health safety, threats of lack or deficit in water supply and threats to the environment. This process should include the analysis of the existing condition, possible potential threats and safety and repair procedures.

The objective of this paper is to point out existing risks of current design and management strategies in water supply systems and to identify possible ways of designing and operating schemes which minimize these risks. This paper is motivated by the observation that existing design principles and engineering rules (best practice) seem to cope insufficiently or even conflict with current trends of declining water demand. In order to evaluate this situation, an agent-based model comprising the current rules of best practice was developed in a participatory process. Once the model was validated with data sets from a real utility, multiple-scenario testing was used to explore different design strategies, thus allowing ideas for developing alternative management and design schemes to be generated. The simulations show that the traditional risk of insufficient supply security must be supplemented by considering the opposite risk of excessive security (over-capacity). The introduction of demand-side measures may help to calibrate existing best practice with the trends of the current operating environment. Ideas are brought forward on how to shape incentive systems for stakeholders in order to facilitate such a shift.

Local Body

This study was carried out during the period from March to August 2018. Published literatures and some unpublished data were collected from different sources and analyzed. It was found that the community people do not have good understanding and adequate participation on the sustainability of water supply systems. They only have interests in the regular flow in taps. They are also less aware in the regular repair and maintenance of water supply systems. Furthermore, the expectation of community is always financial support from local body and donor agency. The governance part of water user’s committee was also found unsatisfactory. Thus, the people should be provided with capacity development trainings for the sustainable development of community water supply system. similarly, implementation of water safety plan, and regular monitoring from local body are crucial activities that should be given high emphasis for the sustainability of rural water supply system.
