Comprehensive water audit creates a detailed profile of the water distribution system, maps water intensive units, thereby facilitating effective management of water resources with improved reliability. It helps in diagnosing of the problems faced to recommend appropriate solutions. It is also an effective tool for realistic understanding and assessment of the present performance level and efficiency of the water management service and the adaptability of such a system for future expansion.
