What solution to have enough water for 9 billion people on Earth?

Clean water is synonymous with life, but people are facing serious water scarcity, how to solve this situation?

Clean water solution for more than 9 billion people on Earth

India is the second largest country in the world, about 1.2 billion people. In particular, 86% of residents are living in rural areas, where clean water sources are becoming increasingly scarce. According to statistics, by 2050, the world population can reach 9 billion people. A question arises, is there enough leftover water on earth to supply these 9 billion individuals? Recently an Indian organization has successfully launched the 'smart well' , which is the answer to the problem of thirst for clean water, which is already extremely urgent globally.

Clean water is one of the most difficult problems in populous countries like India.

According to a recent survey, up to 80,000 square meters of land in India contain water, but the entire volume of water cannot be used for domestic and irrigation purposes due to salinity. Not stopping there, 8 billion of local residents received another sad news, currently there is no radical solution to the problem of desalination for salty water, leading to a waste of water resources. great.

Understanding this situation, the construction engineers of Sehgal, a non-governmental organization with 16 years of experience, have designed a smart well that specializes in capturing rainwater for the needs of clean water for people. rural people. This new solution proved very effective and safe.

The new 'back to soil' solution was soon tested in many places in India, using a pipe designed to thoroughly capture rainwater from places like a roof. During the rainy season, this pipe will carry water from the supply to the ground, filling the underground waterways which have been exhausted for a long time. Excessive use of water from the ground has led to a situation where the rock layer keeps fresh water dry. In the current situation, the solution "pumping water back to the soil" seems to be the best solution.

However, this solution has not been approved due to some problems arising: as people know that rain water is always floating on the surface because the density is smaller than salty water. This makes it difficult to extract fresh water for people's use.

Unbound, Sehgal's engineering team continues to research and release a new water supplement . The new design is an extended version of a traditional well that makes the surface of the ground become higher and the underground part becomes deeper than usual. The filter in the new shape proved to be quite effective, the hydrostatic pressure in the well increased, allowing the collected fresh water to go underground and create bubbles, keeping this state in the saline water. It's hard to believe, but the saline water block in the ground helps shape the block of clean water, making it always clean and usable.

Fresh water from the block of water will be put on the ground with a hand pump, but this water can not be used until it is put through the filter system to remove all impurities to ensure cleanliness and Pure when coming to the user's hand.

This success has helped Sehgal become one of 14 organizations selected by the United Nations from 800 organizations worldwide in the competition because of '17 sustainable development goals' . Last month, Sehgal had a presentation on inventions for her new community at the United Nations headquarters in New York.

The invention of this ' smart well' has opened a new direction for our planet. In the current global population overload, clean water is synonymous with life. According to the Global Water Forum, the demand for water will increase by 55% when the global population reaches 9 billion by 2050, the only way for us to continue is to research and develop devices. as intelligent as what Indians have been doing.
