Why Rain Water Harvesting?
---------- Important Reasons ---------
☑ To arrest ground water decline and augment ground water table
☑ To conserve surface water runoff during monsoon
☑ To beneficiate water quality in aquifers
☑ To inculcate a culture of water conservation.
----------- Larger picture -----------
☑ Global estimate: more than 1.5 billion urban dwellers rely on groundwater, currently
☑ Reduction of recharge area due to roads, building and pavements
☑ According to WWF in 2030 only 50% water will be available.
------------- Urbanization -------------
☑ Rapid urbanization results in a large scale consumption of ground water.
☑ Innovative urban planning contributes to economic development by strengthening urban infrastructure.
☑ Urban sector presently contributes about 62%–63% of the Indian GDP and expected to increase to 75% by 2021.
---------------------------- Advantage of Rain Water Harvesting ----------------------------
☑ Recharge of Groundwater replenishes the deeper layers of the earth’s crust which in turn insulates the earth from rise in temperature, reducing global warming
☑ Reduces hardness, salinity and TDS contents in the bore well.
☑ Reduces significant carbon footprints.
☑ Checks overexploitation of groundwater source.
☑ Prevents waterlogging in low lying areas.
☑ Rainwater harvesting helps utilities reduce peak demands during summer months, saving treated water for more important and appropriate water uses.
☑ While rainwater can be a perfect primary water source for many uses and situations, it is also a great backup water supply for emergency situations.
