Abstract: Reliability analysis of urban water distribution networks (WDNs) has become a prerequisite for allocation of funds for their installment, upgradation and maintenance, etc. Extensive research has been carried out in the field of mechanical and hydraulic reliability. However, another important field that deserves attention is the water quality reliability analysis in a WDN. In the past, a single heavy disinfectant dosage at the treatment plant was considered sufficient to deliver safe drinking water to the consumers. However, with the growing awareness of negative impacts of chemicals on human health, it has become necessary to restrict the maximum disinfectant residual in water. Also, a minimum level of residual disinfectant concentration is to be maintained throughout the WDN to safeguard water from possible contamination. This necessitates boosting of disinfectant in a WDN. Chlorine is the most commonly used disinfectant in urban water supply schemes. Booster chlorination (BC), therefore, has acquired a greater significance in urban WDNs. In the present study, a methodology has been suggested to determine the minimum number of BC stations in a WDN to satisfy the residual chlorine concentration goals at the consumer nodes. The optimal location of BC stations is identified for minimizing the required dosage of chlorine. Thereafter, the reliability analysis of water quality is carried out when the BC stations are subject to failure for a fully operational WDN. The methodology has been illustrated with the help of a hypothetical WDN. Copyright ASCE 2004.
