Most important and need of the hour issue is water conservation and water pollution. As the whole world is suffering from its population growth and worst water pollution problem due to its industrial growth. Due to this mankind is suffering a lot and most of the developing countries like India and China are unable to provide clean and healthy drinking water to its most of the citizens living in rural areas. Many methodologies are exist to provide the solution for the water leakage and water contamination level detection process, but most of them are relying on the electronic sensors and other electronic gadgets. So proposed methodology put forwards a simple and effective methodology of detection of water leakage based on the hyper graph formation for water distribution network by measuring the water collected levels at the check points using goal programming technique. And again Fuzzy logic is used to detect the water contamination level using its velocity at different checkpoints of the water distribution network.
