Facing up to the water crisis
Conservation measures such as rainwater harvesting and recharging of groundwater need to be generally well established in both rural and urban areas. Amita Bhaduri posted 1 year ago

The conventional freshwater sources available in India are being currently overexploited, leading to widespread environmental degradation and depletion of freshwater resources especially groundwater. To sustain the needs of an increasing population and ecology, our consumption of water far exceeds the rate at which we are recharging water sources.

Harvesting rainwater effectively
An innovative project makes rainwater harvesting easier and more effective in certain areas of Mewat village with increased groundwater salinity. Amita Bhaduri posted 3 years 2 months ago

One of the major causes of deterioration of water quality is the increase in overall salinity. Total hardness and the presence of materials like fluoride, nitrate, iron, arsenic, and toxic metal ions determine salinity levels in groundwater. With the demand for groundwater growing rapidly, its exploitation is also accelerating which causes depletion.

The innovation was introduced in a government school building in Untka village located in Mewat district of Haryana.
