Urbanization is responsible for physical and socio-cultural changes of any area. To make way for rapid urbanization, horizontal and vertical expansion of small cities happen which pose severe threat to the existing infrastructure. This process gradually changes the land use and land cover. Eventually water bodies are lost and all these gradually raise issues with water demand and supply, drainage, water-logging, dependency and overexploitation of ground water, contamination and consequent declining of ground water. Proper water management is required to cope up with all the issues. Way-out has been found through rain-water harvesting method as applicable in the urban area. Barasat Municipality, district head quarter of North 24 Parganas in West Bengal and in the outskirts of Kolkata Metro area, has been experiencing population growth at very fast rate which had been aggravated by migration factor as well. This population growth has put tremendous pressure on available natural resource of water. The gap between water supply and demand is being widened and invites problems at present and in near future. It is time to solve the problem of sustainable eco-friendly management that is Rain Water Harvesting (RWH).
