Increase in urban water networks, network management is one of most important problem in which the parameters of the network pressure and leakage at night in search of networks and connections will be worn. Given that the urban water networks with more than 30 years old have been worn and is part of the network and still have not replaced the night of exhaustion and pressure leakage is due to i...

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...

introduction: corrosion and scaling of water in distribution systems in spite of imposing economic and aesthetic problems can lead to adverse effects on consumers' health. the present study was conducted to evaluate the corrosion and scaling of water distribution system of sarableh city (ilam, iran) during summer and winter seasons in 2014. materials and methods: totally, 60 samples of wat...

Abstract The volume of water losses depends largely on the approach to active leakage control networks. Losses comprise physical (leakages transmission and/or distribution networks, at utility’s storage tanks, and service connections), commercial (unauthorised consumption metering inaccuracies data handling errors) unbilled authorised (unbilled metered unmetered consumption). Reduction real may...

a water distribution network is subjected to various abnormal conditions such as pipe breaks, pump failures, excessive demands etc. in the design period. under such conditions, the network may not be able to meet required demands at desired pressures, and becomes deficient. traditional network analysis assumes nodal demands to be satisfied and available nodal pressures are calculated. however, ...
