Bangaluru; India’s Software Capital has come to standstill on Cauvery river water dispute. Riots over water are increasingly shattering peace, tranquility and public life mainly due to growing shortage of water. India accounts for about 17% of world’s population but has only 4 % of world’s fresh water resources. Approx 1544 Cubic meter per capita annual water availability is driving us from Water Stressed to Water Scarce status since our demand and consumption is rapidly growing…
At present Irrigation sector consumes about 84 % of total available water followed by Industrial at 12 % and Domestic at 4%. All three sectors are mainly dependent on Ground Water. About 62.4 % irrigation needs, 85 % of rural drinking water needs and 50 % of urban water needs are fulfilled from Ground Water. This has resulted in 62.2 % of 6600 blocks across India; being categorized as over exploited by Central Ground Water Board. And continuous irresponsible over exploitation at current rate will lead to exhaustion of ground water in time to come.
Key ares that can help us to bring positive water balance are rejuvenation and recharge of ground water as well as restoration and renovation of existing water bodies by adopting techniques of harvesting huge volume of Rain Water. We need to capture each drop of water falling on our roofs and surface to combat the growing shortage of water. Rain Water must be captured, filtered and directly put to reuse for all domestic applications after storing in underground, over ground and overhead tanks.
Rain falling on open lands, lose soil / grounds, roads, large premises can be channelized to low lane areas where it can be diverted back by Injection well / Recharge well technology to Mother earth in order to recharge bore wells of surrounding localities.
It’s high time to wake up to the call and adopt Rain Water Harvesting to resolve water conflict and bring positive water balance for Sustainable Environment. https://www.vardhmanenvirotech.com/blog
