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.
