Complexity in water distribution systems makes leakage detection and its monitoring a difficult task. Leakages in water distribution systems are caused due to damages in pipes, lack of maintenance of pressure due to uncertain demand and various operating conditions. Therefore, to manage the pressure in the water distribution systems it is necessary to identify appropriate leak location. Various studies on pressure management focused on optimal sensor placement for leak localization considering various constraints cost of sensors, demand uncertainty, damages and burst in pipes and few focused on valve location and optimization for control of pressure. The main aim of the paper is mainly to provide a comprehensive review of various studies related to leak detection, location and monitoring strategies. Also, it mainly focuses on pressure and water quality sensor placement in water distribution systems with sole and integrated approaches for leakage minimization and contamination intrusion in water distribution systems. A critical review of available methodologies for leakage detection, location, monitoring including existing simulation tools, solution approaches, and available methodologies for pressure sensor placement, technical challenges, and future research direction is presented. Till now no reviews are presented for pressure and water quality sensor placement in water distribution systems along with burst detection.

However, due to growing challenges such as expanding populations and urbanization, climate and demographic change, infrastructure deficits and aging, inadequate maintenance of water systems, water scarcity, adverse health effects and rehabilitation costs etc. which effects on water quantity and quality in water supply systems. Further, available water sources throughout the world are becoming depleted due to industrialization and this problem is increased with rate of population are increasing specially in developing countries like India. Current issues and challenges of urban water supply systems are highlighted in Table 1. A water distribution network (WDN) is an important and major component of urban water supply systems. Water loss due to leak in pipelines is one of the major challenges in efficient 1364
