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 wate...

A Tabu Search optimisation technique is proposed for designing, planning and maintaining water distribution systems. As design and maintenance of pipe networks for water supply distribution require high costs, achieving the highest level of performance of existing networks at minimum costs is mandatory. The problem involves setting a lot of variables, as location and diameters of new pipes, ope...

The efficient long term management of large-scale public funded assets is an area of growing importance. Ageing infrastructure, growth, and limited capital all result in the need for more robust and rigorous methodology to prioritise rehabilitation and renewal decisions and more importantly, to forecast future expenditure requirements. The overall objective of this research is to develop a Baye...

the world health organization’s (who’s) world health report 2010, “health systems financing, the path to universal coverage,” promoted universal health coverage (uhc) as an aspirational objective for country health systems. yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...

Sensor networks are currently being trialed by the water distribution industry for monitoring complex distribution infrastructure. The paper presents an investigation in to the architecture and performance of a sensor system deployed for monitoring such a distribution network. The study reveals lapses in systems design and management, resulting in a fifth of the data being either missing or err...

Background: Internal corrosion and the formation of scale in water distribution pipes are the most important problems for an urban water distribution system. Physical, chemical, or biological factors can lead to these two processes. Internal corrosion and scale formation can impact health, economy, and aesthetics. This study assessed the physicochemical quality parameters and evaluated the pote...

In recent years, GIS applications in water resources management have become widespread and diverse in the Province of Ontario, Canada. Application areas include urban infrastructure master planning for storm and sanitary drainage systems, water distribution, watershed planning, and regional groundwater protection. This development has occurred despite the challenge faced by users that base data...

infrastructure plays an important role in the process of economic development. access to such infrastructures as safe piped drinking water, educational and health services, electrification and efficient transport system enhance human welfare. the main objective of this study is to determine the contribution of the main types of infrastructure investments to reduction of poverty and more balance...
