Water Conservation

Tackling water scarcity problem for next generation


India’s water environments are amongst our most valuable assets. Unfortunately, the solid and liquid waste people drop on the ground or dump in drains eventually ends up in a water body somewhere. But, we have many sorts of technology working to minify it’s effect. Even, rain washes pollutants and waste from our streets into drains which is a way to reduce the surface pollution. But, what about the groundwater?

Underground water is being polluted mostly by effluent from factories to avoid costs for dumping in the rivers. We currently have working treatment units that are intended for treating the waste that industries dump before they reach the rivers. But, not all of them are working. And, these industries deceive the authorities by demonstrating their use when in reality, they are not working on a regular basis and instead their waste is reaching the ground.

There is not a proper mechanism for treating the waste which reaches the ground and the industries are dumping their waste into the underground water through pipes. Some places, even illicit use of rainwater harvesting pipes is being done. That is, they are used for putting their chemical waste into the ground. This poisons the ground water which is gonna affect the next generation.


To begin with, as recommended by NGT we should be regularly charging all the industries, a minimal fee and pool them to install several small Sewage Treatment Plants(STP) which are to be run by the government itself. Also, there are some technologies present which takes up very little space and uses less electricity like UASB/DHS. So, instead of relying on the industries to install small waste treatment units, we should install such mentioned technologies and audit on a regular basis to ensure that they are working.

The suggested STP’s would create employment for the local crowd which is another positive coming out of this. Also, this would ensure cooperation of government and private industries as for this to succeed, both of them needs to go hand in hand. And, through this we might be able to defend the survival of a precious resource for the upcoming generations.

Results have shown that UASB/DHS has low power consumption i.e 5,000 INR/MLD/month in comparison to the 61,000 INR/MLD/month of ASP(Activated Sludge Plant) which is the current technology used in Delhi.

It clearly shows that UASB/DHS would be a perfect alternative for implementing such conservative measure on a short scale.
