a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such...

Water distribution networks are one of the most important elements in the urban infrastructure system and require huge investment for construction. Optimal design of water systems is classified as a large combinatorial discrete non-linear optimization problem. The main concern associated with optimization of water distribution networks is related to the nonlinearity of discharge-head loss equat...

evaluation of any irrigation system consists of analyzing the measurable performance of the system in real conditions as well as during the normal operation of the farm. irrigation evaluation is a management tool that allows the system manager to make the best use of what is available. unfortunately, in most regions of iran, after the implementation of irrigation systems their performance is no...

Infrastructures such as energy, transport, water, waste and telecommunications are essential to the sustainability, social wellbeing and economic prosperity of nations. In meeting future infrastructure needs of a growing global population there is a need for creating resilient infrastructures, which can withstand large human induced or natural shocks. Understanding systemic vulnerabilities and ...

Research in the area of sustainable urban infrastructure reflects the need to design and manage engineering systems in light of environmental, economic, social and technical considerations. In the water sector, the main challenge for the engineer is the development of practical tools for measuring and enhancing the sustainability of urban water infrastructure over its life cycle. The present st...

In this study, the recently developed method, Tug of War Optimization (TWO), is employed for simultaneous analysis, design and optimization of Water Distribution Systems (WDSs). In this method, analysis procedure is carried out using Tug of War Optimization algorithm. Design and cost optimization of WDSs are performed simultaneous with analysis process using an objective function in order to sa...

UNLABELLED Bacterial communities migrate continuously from the drinking water treatment plant through the drinking water distribution system and into our built environment. Understanding bacterial dynamics in the distribution system is critical to ensuring that safe drinking water is being supplied to customers. We present a 15-month survey of bacterial community dynamics in the drinking water ...

The South African civil engineering fraternity has grown to accept 24 m as the design criterion for minimum residual pressure in water distribution systems. However, the theoretical peak demand in many systems has increased beyond the point where minimum residual pressure exceeds 24 m – at least according to hydraulic models. Additions of customers to existing supply systems have led to increas...
