21 Indian cities, including Bengaluru, Delhi, Hyderabad, and Chennai is expected to run out of groundwater by 2020, will affect over 100 million people, reports NITI Ayog.
It continued that around 40 percent of the country’s population will have no availability of drinking water by 2030. Hence, the situation is alarming, given the fact that the year 2020 is not very far.
Four water bodies, three rivers, six forests, and five wetlands have completely dried in Chennai despite having better rains and water resources than any other metropolitan cities, reads the report.
Former Director of National Water Academy Professor Manohar Khushalani said that “the government is depending upon the desalination in Chennai which is very expensive also however they forget that the earth is a limited planet and oceans will dry. What will we leave for our children and grandchildren? We may have a lot of money but we cannot ask our children to drink money instead of water. Using ocean water and desalination is not the solution but water harvesting is.”
“It is a collective responsibility of the government and people of the country to save water and contribute to increasing the groundwater levels,” added Mr. Khushalani.
At present, Manohar Khushalani is working as a professor in Delhi’s Indraprastha Institute of Information Technology has also authored books “Irrigation Practice and designed in five volumes.”
“It is not very difficult and expensive to harvest rainwater. One can easily do it commonly in group housing societies or individually. We will just have to make our heart little bigger and more responsible to be thinking about our next generation,” informed Mr. Khushalani.
He has also developed a water harvesting structure inside his residence, in which he has been harvesting rainwater since 2003, assisted to raise the groundwater level in the area.
Mr. Khushalani was quoted saying, “I made this water harvesting structure in 2003 when my sixty feet deep tube well dried up. I decided to put all rain water collected on my terrace into it. There are two conditions in doing rainwater harvesting. Number one, first rainwater should not go into it, secondly filtered water should go into the ground otherwise it will contaminate the groundwater. The rainwater which is collected on my terrace flows through a pipe which is connected to the bore. After sixty feet, the soil filters the water by itself. The water which falls from the terrace or from height should be harvested but not the water on the roads during rains because it carries lots of dirt with it which may lead to groundwater contamination.”
He also suggested that the regions that are facing scarcity of water shouldn’t do farming of sugarcane as it absorbs a lot of groundwater to grow. Mr. Khushalani concluded, “By becoming aware today we can avert the danger tomorrow.”
