The presented method of determining the risk associated with the failure in water supply systems (WSS) was based on the results of study on the operation of water supply networks and the related failures. The implementation of fuzzy logic proposed in this paper allows to determine the failure risk depending on defined by fuzzy functions two parameters: the duration of the lack of water supply a...

The paper approaches the optimization of water distribution networks supplied from one or more node sources, according to demand variation. Traditionally, in pipe optimization, the objective function is always focused on the cost criteria of network components. In this study an improved linear model is developed, which has the advantage of using not only cost criteria, but also energy consumpti...

OBJECTIVE To assess the contamination level of total and faecal coliforms in water wells and distribution networks, and their association with human health in Gaza Governorate, Gaza Strip. METHODS Data were obtained from the Palestinian Ministry of Health on contamination of total and faecal coliforms in water wells and distribution networks, and on the incidence of water-related diseases in ...

Complex water networks, which have been structurally organized into Regional Supply and Urban Delivery networks from a functional perspective, are facing more challenges in their real-time control because of the reduced water resources, intensive energy requirements and increased attention towards the environmental impact of water use. Optimal management of complex water networks involves more ...

This paper exam ines the emergen ce of a new logic of water management in develop ing cities. We argue that water provision is characteri sed by two largely disconnected circu its of water supply. Formally organ ised distribution networks provide a publicly subsid ised service to higher-in come users, while an informal system of water vendors provides a more expensive supply to margin alised co...
