Urban population growth, particularly in developing countries, places immense pressure on water and land resources; it also results in the huge water usage most of it not potable at all. So, water treatment is increasingly necessary due to potable water shortages and growing needs of global population. Today, it is not at all safe to use water directly from rivers, reservoirs, and lakes as it contains various micro-organisms, pathogens, and other contaminants that have an adverse effect on the health of humans, plants, and animals. This situation of unhealthy and unsafe surface water has generated the need for the Water Treatment Plant. This study aimed at assessing Construction Project Management practice of Water Treatment Plant of capacity 5.5 MLD for the supply of potable water to 30 villages in Shegaon, Maharashtra. Therefore, the function of construction project management which includes defining the requirement of work, establishing the extent of work, monitoring the progress and adjusting deviations of work. This aims to achieve goals of project leading to completed construction by virtue of planning, executing and controlling time, funds with human and technical resources for the construction of water treatment plant. Data for the study was obtained through well-structured questionnaire administered to executive engineer, contractor, client and site engineer working on the project. This study is carried out for the knowledge of implementing, assessing and adapting the construction project management of water treatment plant.
