Rain Water Harvesting
Climate Change is evident in the change of precipitation
trends that include large annual fluctuation of rainfall and
snowfall, thus an increase in erratic rains. This has equal
impact on water bodies such as rivers, lakes as well as
groundwater sources such as aquifers which have reported a
drastic change of water volume, an increase of water
temperature and the declining water quality.
Water shortage and quality issues have risen as basic and
critical concern worldwide. Water is lost from the phase of the
earth in several ways, including evaporation, animal and plant
consumption and largely through human-related development
projects. In general, the high demand on water resources for
development globally has put water resources under pressure;
hence there is an immediate need to urgently find innovative
opportunities that will enable development and human well
being without undermining ecosystem services. However,
there is only one way in which water comes back or it's
regulated back to the earth; through rainfall.
The most wasted water is the spillover, which goes to the
ocean alongside the most fertile soil. “The running water has
to be made to creep, the crawling water is to soil and get
stored, to be utilised in the dry days," This is the
straightforward meaning of rainwater harvesting.
Rain Water Harvesting (RWH) is a method of collecting,
storing and conserving local surface runoff rainwater.
Water is essential to all life – human, creatures and
vegetation. It is therefore important that sufficient supplies of
water be created to support such life. Development of water
supplies ought to be embraced in such a way as to preserve
the hydrological balance and the organic functions of all
ecosystems.
Therefore Rain Water Harvesting is very essential for humans,
creatures and plants.
