Abstract
This study aims to identify the potential of rainwater harvesting on a neighborhood scale
by doing qualitative and quantitative analysis. Small neighborhood of Samakhusi was
selected as a good representative of compact residential urban area. Samakhusi lies in
northern belt of Kathmandu valley where there is high infiltration rate for ground water
recharge but also has water logged streets during rainy days and water scarcity during dry
seasons. Based on a statistical analysis of the rainfall, the amount of rainwater that might
be captured from roofs and ground surfaces was calculated. The standard data from the
literature was used to calculate the potable water consumption of urban residential
households. In this study, potential of rainwater in compact urban area for regenerating
water sensitive urban development was evaluated. And also, a possibility of minimizing
waste water from rainwater harvesting was evaluated. The study also examined case
studies with success stories which reflects improved urban scenario through rainwater
harvesting. Moreover, social perceptive from community, government institutions and
technology providers on rainwater harvesting was also analyzed. Based on these
qualitative and quantitative data, direct and indirect benefits were explored that helps to
improve water sustainability and water sensitive planning of an urban residential area.
