In this few  year, these villages are facing a drinking water problem. 

Now you can see the ample of water. In just one year? 

Just in 45 days, Not one year. 

The story begins with the uber-famous Bollywood star, Aamir Khan, who has a decades-long career full of mega-hit movies. He hosted a talk show that examined the problems that India faces and became aware of the water crisis that threatens the very fabric of Indian society.

 He learned that drought could be defeated and built a team of dedicated water stewards and founded the Paani Foundation's Water Cup. The Water Cup is a contest between villages in the state of Maharashtra to see which village could install the most water harvesting structures in a 45 day period. There are many thousands of villages that have competed and the resulting structures equate to over 145 billion gallons of water storage capacity, built in just four years! By my estimation, that would make this the largest restoration project on the planet. 

I needed to see this for myself. So I traveled to the city of Satara to get a tour of some of the villages with the Paani Foundation's chief advisor. I am here, in the state of Maharashtra with Dr. Avinash Pol of the Paani Foundation. 

We began with a visit to the village of Garavadi, in an arid region of the state that receives between 200 and 300 mm, or 8 to 12 inches of rain in an average year. The village has a large watershed, over 2500 acres. It has a number of ponds that would fill in the monsoon rains. 

But the upper watershed was draining water too quickly So the groundwater became depleted. And in the dry season, the village had to bring in tanker trucks full of water, just to drink, with no water for crop production. But when I arrived in the village, over 2 months since the last rainfall, water flowed over the roads. And green, verdant crops surrounded the village centre We were greeted by a large group of men who would accompany us throughout the watershed to see their work. The upper zones appeared to be primarily grasslands with rotational grazing of large herds of goats The main structures used to harvest water here are called CCTs or "Continuous Contour Trenches" These are the same structures that we call "on-contour swales" in the United States. 

In the month of December, they start facing a problem of water scarcity. Every year This year, they took part in the Water Cup competition. This was the first year They treated the watershed in different areas. 

You can see the hilly areas? These are the three hilly areas. One is this. Second is this. Third is this And fourth and fifth. Five hilly areas. From the top, they started the work. Right now, we are on the top surface area. On the top surface area, we preferred CCTs [Continuous Contour Trenches]. The treatment is a CCT These are the CCTs. The CCTs were made by the machines. It is around 1 meter by 1 meter So CCTs, I think are basic treatment plans in a watershed development. 

This is the basics. Otherwise, what happened? 

The drop of water falls on the top area. It will come directly. That's why the rock gets exposed. 

If you create the obstacles; this is the obstacle, no? The water comes from the top area. There is one obstacle From here, it goes in a downside. There is another obstacle. It also helps to increase the groundwater table. Come, see the moisture! Okay? 

We, you just observe the grass in this area. In some parts, you feel a dry grassland. Okay? In some parts. But, in some areas, you can see wet grass. This is wet grass. Some areas, there is dry grass. Why is this wet grass? Because of the moisture. It's the effect of CCT. 

The sixth November is the last rainfall. Last rainfall date is the sixth of November. So more than two months. More than two months. This year, rainfall is more. Around 500-550 millimeters. Otherwise, it is in a range of 200 to 300 millimeters. 

That's why they are dependent on tanker water Government supplies tankers for the drinking water purpose. So this is called the farm pond, which is having one inlet and one outlet. In this farm pond, we are not putting a plastic sheet. Otherwise, percolation will not happen. So, this is for percolation and not for irrigation. 

This is for the percolation purpose. There is an outlet of the farm pond. Once it overflows, it flows from there. Again it will go downside, into the CCTs. This is the chain. This is the interlinking. A few minutes back we walked from the same area, no? But we never see flowing water. Because it is undermined (underground). Now it is exposed. And this is the spring. 

You can watch it. This is the result. So that's the basic science behind it. Water flowing during heavy rains is soaked into the ground in the upper watershed using various water harvesting structures. 

These structures create obstacles to the water flow, and then the water percolates down into the water table. When we go lower down in the watershed, that percolated water then surfaces as springs and a rising water table that fills ponds and waterways. The water is then pumped from ponds and wells to irrigate crops during the dry season. So now villagers can grow wet season and dry season crops, and also have groundwater stored in reserve for when rains fail. 

This means that they do not need to import water in tankers, or migrate away from the villages to find work when water is scarce. 

It means people stay in their villages with abundant food and a good farming income Restoring water tables actually fixes a lot of social problems When these people have a stable water supply, then they have a stable farm income 

This means they don't need to leave their villages in search of low-wage work in India's mega cities 

The Paani Foundation’s Water Cup competition is much deeper than just water.
