ESSAY ON RAINWATER HARVESTING
The rainwater harvesting means the technique used for collecting the rainwater and storing it by using various means of different resources for the future use. The purpose of cultivation, etc. the rainwater can be collected into the natural reservoirs or artificial tanks.
Another method for collection is infiltration of surface water into the subsurface aquifers before getting lost by surface overflow. The harvesting of the rooftop is also a method of collecting rainwater. The rainwater harvesting is more important for the people living in the fewer rainfall areas. There can be a continuous seasonal crop harvesting using the collected rainwater even in the lack of regular water supply. Whenever it rains, rain water gets collected into the man-made ponds or tanks.
The benefits of Rainwater Harvesting
It helps in reducing the water supply bills, especially to the institutions.
Rain water recharged to the ground positively affects groundwater quality by diluting fluorides, nitrates and its salinity.
It contains almost neutral ph and zero hardness which makes it more able to be used in homes, industries, institutions and other commercial establishments.
It may reduce the stress of public water supply sources.
Recharge of rainwater to the ground prevents sea-water immersion into the freshwater bodies in the coastal areas.
It also helps in controlling urban flooding if people do rainwater harvesting from rooftops.
It reduces water demands of people from the municipality thus it lessens energy consumption too in disturbing water all through the city.
The drop of rain water is a blessing of God to the people on the earth, fresh rain water falls on the ground like pearls, so everyone should understand the importance of rain water especially in developing regions and rural areas which is lack of natural water resources. We must always try to collect the rain water without wasting through rooftops and along streets run off. We should bring our old traditional harvesting practices using new and effective technologies to make easy water supply in all the regions.
The hand pumps, wells, and other resources of groundwater levels cannot fulfil the potable water need of many peoples. The rain water harvesting also saves the energy as the energy is needed to operate the water system. many systems require only hand pump to create the water pressure in household pipes. The local erosion and flooding from impervious cover associated with buildings are lessened as a portion of local rainfall is diverted into collection tanks. Therefore, rain water is one of the purest sources of water available. Its quality almost exceeds that of ground or surface water.
The rainwater does not come into contact with soil or rocks where it can dissolve minerals and salts nor does it come into contact with many of the pollutants that are often discharged into local surface waters or contaminate groundwater supplies.
