Drinking water for human health and well-being is crucial. Accidental and intentional water contamination can pose great danger to consumers. Optimal design of a system that can quickly detect the presence of contamination in a water distribution network is very challenging for technical and operational reasons. However, on the one hand improvement in chemical and biological sensor technology h...

the present study was undertaken to analyze factors affecting farmers' participation in the management of water network in jarghouyeh district in isfahan county. a descriptive correlation research design was adopted for the study. at the field work level, surveying was the basic method which was taken into consideration. the statistical population of the study consisted of about 1810 membe...

water is the most essential component for sustaining lives of humans and other living creatures. supplying potable water with adequate residual pressure is a fundamental responsibility of city administration, which they do during normal conditions. but sometimes, abnormal conditions are formed resulting pressure deficient conditions during the daily operations of water distribution networks. th...

The reliability of a water distribution network (WDN) is a function of several time-invariant and time-dependent factors affecting its components and connectivity, most important of which have been shown to be the network's topology, its operating pressure, the type of key components (such as the diameter, length, material and age of water pipes) and the network's historical performance (such a...

The development of bacterial communities in drinking water distribution systems leads to a food chain which supports the growth of macroorganisms incompatible with water quality requirements and esthetics. Nevertheless, very few studies have examined the microbial communities in drinking water distribution systems and their trophic relationships. This study was done to quantify the microbial co...

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...
