Abstract :
Water is the most valuable resource which is
available on the earth’s surface, covering 2/3rd part of the
total earth’s surface. Human requires water for a variety
of tasks in our daily lives, so life would not exist without
it. As the world population is increasing day by day, the
demand increases for quality drinking water. In a
growing country like India, Nepal having scarcity of
water sources, became a major problem due to the
increase in the consumption of water. Besides this many
coastal parts of Nepal and India are challenged by floods
due to heavy rainfall during the monsoon season. Due to
the increasing population, weather change, variation of
rainfall within the country, and sudden disparity of
metrological parameters like humidity, the surface, and
sub-surface resources are constantly depleting in many
countries. Hence its proper management could reduce
problems due to shortage of water and food crises. So
rainwater harvesting has proven to be one of the most
cost-effective and environmentally friendly methods to
overcome this problem, conserve the water for future use,
and recharge groundwater. The RWH technique is used
to resolve the problem of water scarcity problems during
the non-monsoon season by storing 129.5m^3 in a year on
the rooftop of the house. This initiative helps to utilize the
water supply for household purposes, and agriculture and
also will help in the recharge of the groundwater. There is
greater chance that the rainwater might be contaminated
by dust, floating substance, bacteria, and hazardous
Chemicals that require treatment before usage. We have
used slow sand filtration and solar technology methods to
reduce pollution. This study aimed at designing a rooftop
rainwater harvesting structure for a rural house in
Dhangadhi Nepal. The roof of the house was chosen as
the required catchment area for rainwater harvesting
taking into the consideration of the water demand for
household purposes. The necessary data such as
catchment regions and average precipitation are
gathered. In this paper selection of good rooftop
materials, basic rooftop designing for rainwater
harvesting, basic cost analysis, and solar power pump for
lifting the water for future use have been done.
