RISK ASSESSMENT OF WATER DISTRIBUTION NETWORK USING FUZZY BASED SYSTEM

The challenge which is faced by the municipal engineers is to assess risk associated with the buried infrastructure. Assessment of risk associated with water distribution network is most challenging as they are undergrounds, operated under pressure and are inaccessible. The present paper develops a methodology to evaluate the risk associated with each segment of network using fuzzy rule based system (FRBS).Total eight risk of failure parameters are considered which deteriorate the segment and

Base System (FRBS); MATLAB R2008a-fuzzy tool box. INTRODUCTION Water distribution networks are those infrastructures which are buried and have received very little attention from the municipalities and decisions makers. Now, with time it is found that the breakage rate as well as the cost which is associated with the failure of the distribution network has led to such a level that has drawn attention of municipalities as well as the decision makers. Now, it is obvious that with increase in breakage rates of the water distribution network will led to decrease in hydraulic capacity as the system starts deteriorating. As a result, dealing with the risk associated with the water distribution network has been enduring a great transformation in concept from reacting to failure events to taking preventive actions which will maintain the water distribution network in good working condition. The urban water supply is based on a large and complex infrastructure that has been expanded and developed during the last century. While getting older, water supply assets, primarily pipes, are exposed to the deterioration process and consecutive pipe leakage and then failure of that pipe. It is common that for cities there occur hundred and even thousands of water pipelines break in the water distribution network every year. Nowadays, most Indian cities observed high rates of failure in water distribution network. Due to lack of information and data viability, there is no measurement of water leakage from the pipelines in Indian city. It is also found that the water pipeline networks in developing countries are in poor condition. This deterioration not only manifests itself in increased operating operation and maintenance
