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.
