The coastal zone is the most industrialized and urbanized area in the country. Most coastal areas in the world are dependent on local fresh groundwater resources. Most of the oil refineries and industries are situated in coastal areas and often cause soil and groundwater pollution, due to potential leakages of petroleum products. The Mumbai refinery is one of the largest refineries situated in coastal areas. The annual freshwater consumption at Mumbai refinery for various process and non-process requirements is approx. 35 lakh kL. The deficit of water is outsourced and carted to refinery through water tanker. To overcome the difficulties of outsourcing the water the potential of rainwater harvesting from rooftop of structures has been calculated by considering the present groundwater quality status. A total of 38 locations were identified having rainwater harvesting potential from rooftop of existing structures within study area. The total quantity of potential rainwater harvesting was calculated as 1.45275 lakh kL. This potential of rainwater harvesting from existing structures will mitigate the outsourcing of water and will also improve the groundwater recharge and quality of groundwater.
