MODIFIED DESIGN OF EXISTING URBAN RESIDENTIAL WATER DISTRIBUTION NETWORK BASED ON NETWORK APPRAISAL AND RELIABILITY ANALYSIS

Abstract

Water distribution networks deliver water from its sources to the customers of the network. In Indian cities including metropolitan cities, the water distribution is a major problem. The cities are battling with old water distribution system and the demand has grown beyond the level the system can satisfy. Moreover unequal Head at major nodal points in a water distribution network due to various reasons is adding to the problem. This leaves consumers unsatisfied. The continuous increase in failure of distribution system has reduced the system reliability to a new low. The consumers remain uncertain for the availability of water and reduces their confidence towards existing water distribution network. This leads consumers to harness water through individual bores and hence exploiting water table. EPANET, hydraulic simulation software is used to analyze Head and Demand at nodes in water distribution networks. Simulation results from EPANET helps us to design a water distribution network which provides an adequate volume of water with adequate head to consumers as per their demands under any condition over a period of time. Delhi Jal Board is one of the prime water distribution agency in Delhi. A water distribution network for the Pradhan Enclave in area Burari is being examined for hydraulic parameter sufficiency and its reliability under various water demands. ORGANISATION OF REPORT The study described in this report provides an approach for assessing the performance and reliability of a selected water distribution network for urban residential area. The report consists of six chapters. Chapter 2 provides a synopsis of a detailed review of the relevant literature. Chapter 3 gives the brief introduction of the study area. Chapter 4 provides the methodologyof the processing of data using EPANET hydraulic simulation software. The reliability of the network under study and associated hydraulic parameters are also depicted. Chapter 5 details the modification of the network. Chapter 6 is about the results and discussion of the hydraulic analysis of the urban residential water distribution network.
