Nowadays, issues related to water are considered one of the most significant and vital problems in human societies. One fundamental branches crisis is distribution network-related problems. The present study attempted extract, classify verify failure data obtained from Preventive Maintenance database Birjand Water Distribution Network (WDN). WDN was meshed terms rate failures using a combinatio...

Abstract In Goma Township, the water supply system has become ineffective and insufficient against background of an increasing population with high demand. A study was therefore carried out to assess network Township using three performances indicators a view proposing possible solutions existing challenges. The methodology involved assessment evaluation production, physical characteristics, hy...

Chlorine concentrations in water distribution systems are generally predicted by combined models of reactions bulk and at pipe walls. The structure the widely used EPANET wall-reaction is questioned, as they do not reproduce variation rate with decreasing chlorine observed real pipelines. microbially mediated model (EXPBIO) structurally valid. EXPBIO was extended to calculate mass-transfer coef...

The improvement in energy saving aspects water systems is currently a topic of major interest. utilization pumps working as turbines relevant strategy distribution networks consisting pressurized pipes, using these machines to recover energy, generate green and reduce leakages systems. need develop studies, prior the installation facilities, requires use simulation tools. These tools should be ...

Water distribution networks are vital hydraulic infrastructures, essential for providing consumers with sufficient water of appropriate quality. The cost construction, operation, and maintenance such is extremely large. problem optimization a network governed by the type size pipelines placed in network. This optimal diameter allocation pipes has been heavily researched over past few decades. s...
