Abstract

Rain Water Harvesting, a traditional practice started many centuries ago, has received very little attention in recent times. This thesis describes the adaptation and development of affordable technology for collecting rainwater including that from roof tops; and using this as a valuable source of water to supplement the water need of households in dry seasons and round the year in institution. It also illustrates the effective capturing, retention and controlled release of rainwater. The thesis will substantiate the extent to which adoption of the technology could helps greatly in conserving water resources and at the same time helps to alleviate poverty by improving the quality of life of women and children in under developed parts of Nepal. It is envisaged that the systems would enable poor households in the community to supplement their water supply as well as engage them in kitchen gardening; extend their cropping seasons through availability of water resources, ultimately enhancing food security and contributing to poverty alleviation. This survey is mainly focused on evaluating the existing condition of the rainwater harvesting system whether the system fulfills the required demand. It is also concerned towards finding water consumption pattern for drinking, cooking, washing/cleaning, farming and other purposes. Study of water collection habit is the other aspect of the survey. It includes frequency of water collection from source , time required to collect water and use of saved time by women. Illam, representing a ecological regions is selected as the study area. The district is expected to give the succinct picture of water consumption pattern of the country, as the survey has been conducted in different economic classes and different ethnic groups. The survey also includes the information regarding benefits of RWH system. Primary interest has been given to the safety of water for drinking purpose.
