Abstract

Continuous water supply has advantage over intermittent water supply system in terms of cost, health and user friendliness. Water networks are usually designed to supply water continuously, but over period of time, water network behaves intermittently, without functioning the way it is designed for. Solutions for existing intermittent water supply networks is required to be studied while redesigning with minimum effect on the existing network. Therefore this study focuses on the design of continuous water supply distribution system by redesigning the existing water network system by connecting the dead ends and making the flow continuous. The pipeline and its features are developed in GIS for the height of the nodes and proper placement of the pipes and as for the analysis, pressure and velocity for the water network system is analyzed in EPANET. While the analysis results for the pipelines of CST showed that the pressures are greatly affected by the distance from the source and also by the number of connections for water withdrawals, providing alternative connections and increment of pipe diameter has solved the associated problems. The flow can be made continuous by connecting the dead ends, as it does not allow stagnation of water, which is common problem of dead end systems. This paper shows the comparative behavior between dead-end and ring system of network in terms of pressure and velocity and the effects of building height and topography in the distribution network using EPANET
