The managment of silt washed down by the Himalyan rivers are key to mitigating flood risk in vulnerable regions across India

There are different methods to manage silt load. Soil conservation methods like crop rotation, use of organic matter, contour cultivation and restricted land use are some of the recommended methods of silt managment, especially in the catchment areas of rivers.

Drain Water Harvesting

Water Conservation vs Carry Water by Train, Which is Better

Carrying water by trains could be an emergency measure. Chennai has a strong tradition of water harvesting. But the problem is that most of these structures are either defunct or poorly maintained. Chennai which had 19 major lakes covering an area of 1130 hectares. But these waterbodies have been heavily encroached upon reducing their spread to just about 645 hectares. Its time that we understand the importance of water harvesting.

Froth belongs inside our washing machines. So, what is it doing there on the surface of our water bodies?

Water molecules prefer their own company, so they tend to stick together in drops. We call it surface tension. To make water wash better, we have to reduce its surface tension. The surfactants, that is, the surface active agents in detergents do the job.

Jab We Met: The Han Meets the Yamuna River…

The Han meets the Yamuna river and tells her how even she can flow and flourish in peace.

Han smiled and hugged Yamuna. For a moment, Yamuna forgot the toxic filled surrounding she lived in. Yamuna lowered her eyes and began opening up to Han. “Look where I live Han. I cannot breathe; move my arms or even my feet. Every day, the drains add more filth into the river and the people of the city for whom I travel from so far, do not even throw a glance at me. For them, I am a stinky black drain.”

When the rain gods do not send water for irrigation, farmers look downwards, at groundwater, for help. But, years of groundwater exploitation and lack of recharging, has led to a fall in the water tables. For instance, in north and central Gujarat, water tables have dropped to 20m per decade since 1974, as per a study by the Central Ground Water Board. If this continues, extracting groundwater will get more expensive because we have to dig deeper, or worse, groundwater will be only a myth for future generations.

Reviving a lake using artificial wetlands in Delhi

Wetlands purify water through natural processes where aquatic plants act as bio-filters. Plants absorb phosphates and nitrates from the water and roots help to put back oxygen into the water.

Constructed wetlands are a cost-effective method of treating wastewater and polluted water bodies. These are low cost solutions and can be easily made or replicated.

How the life around the Yamuna River changed with time and people

Tributaries of the Yamuna flowed through the city and several rulers tapped the streams and fed the water through massive sluices into tanks, to provide water for their people. Today, these tributaries have dried up and become cemented tunnels underneath the city that carry sewage to the Yamuna.

Can We Clean Our Rivers from Our Homes?

A few kids were tracking their paper boat in a river. Who was to say they would discover dirty truths.

During heavy rains, they overflow and flood courtyards. These become a breeding ground for mosquitoes. Open defecation near these drains causes the faecal matter to flow into households. The poorly designed toilet pits don't help either, he had explained. Pushpa was jolted when she heard the bell ringing and was swarmed into her class by the excited students.

Can we control the ongoing water crisis all by ourselves? It's not about whose responsibility it is, but what we are doing about it.

“When water became a commodity, I lost my freedom. More importantly, it put a financial burden on those who couldn’t afford to buy it. Today, water companies sell drinking water and advertise it being rich in minerals and full of vitamins. Big corporates such as soda companies have been buying rivers for industrial purpose and farmers have no water to irrigate their fields. As the rivers dry up, animals also start wandering and enter villages in search of water, with a threat of getting trapped or killed.
