Most commercial buildings, large villas, residential buildings and high rises typically use a water management system that is powered by a 3-phase pump or event typically a bank of such pumps. Typically, these pumps are used to transfer water from a ground or below-ground level tank to one or more overhead tank and they are connected to a pump panel for managing this system. There is inevitably both wastage of water and energy in this process when it is managed manually and often even dedicated manual labor to manage the process. The water overflow from tanks or the overworking of the pump are typical causes of such wastage. If a pump runs dry then there is a reduction of pump life as well. An automated water management system, which can be independent or part of the Building Management System (BMS) can serve to eliminate this wastage, by efficiently managing the pumping of water.
