Water distribution systems are complex interconnected networks that require extensive planning and maintenance to ensure that the drinking water is delivered to the consumers. Lack of adequate water supply in urban areas is due to aging water distribution systems and inadequate maintenance of this critical infrastructure (Bhave 2003). The reliability of such deteriorating systems is continually...

Background: Water quality problems are one of the manifestations of poverty and most developing countries including Ethiopia suffering a lot of health problems associated with consumption of contaminated water. Although communities living in urban areas of Ethiopia have access to piped water supply, cross-contamination in the distribution system and unsafe storage are the major source of water ...

Water distribution networks are one of the important and costly infrastructures of cities and many meta-heuristic algorithms in standard or hybrid forms were used for optimizing water distribution networks. These algorithms require a large amount of computational cost. Therefore, the converging speed of algorithms toward the optimization goal is as important as the goal itself. In this paper, a...

With the upcoming widespread distribution of smart meters for electricity, gas and water consumption, new opportunities are closely linked to new privacy concerns. In this paper, we present protocols that can be used to privately compute aggregate measurements, allowing for fraudand leakage detection as well as statistical evaluation of meter measurements, without revealing any information abou...

This paper describes a model-driven decision-support system (software tool) implementing a model-based methodology for on-line leakage detection and localization which is useful for a large class of water distribution networks. Given that model-based leakage localization methods present a certain degree of complexity which limits their use to people with a high expertise in this modelling field...

Water supply access in many developing countries is yet to fulfill Millennium Development Goals. Many local governments are incapable of managing their water resources either due to funding constrains or lack of adequate work force. This often results into poor services with low quality, insufficient and inconsistent delivery of water, leakage and wastage creating water shortages. The water str...

Pressure control in water distribution networks (WDNs) reduces leaks and bursting. Thus, it is regarded as a valuable solution to cut costs related the operation maintenance of WDNs recommended for use deteriorated pipes. However, growing consumer demand satisfactory performance from faucets, combined with reduced pressure supply companies, has resulted an increased need domestic booster system...

In a survey on uranium and 226Ra concentrations in water distributed by Finnish waterworks, 548 samples were analysed that covered drinking water networks servicing 84% of all consumers. Among all consumers, the mean and median uranium concentrations at the point of use were 0.58 and 0.15 g L–1. The mean uranium concentration in drinking water produced from groundwater was 0.88 g L–1, and when ...
