From river to sewer, Paondhoi waits for redemption
Will Saharanpur city’s proposed smart city tag help revive the Paondhoi river once again? Posted on 12 Nov, 2018 11:16 AM

River Paondhoi is best known today as a sewer running through Saharanpur city. Originally, however, it was an important source of drinking water for the city. In its heyday, the water of the river ran ankle deep, just enough to wash one’s feet. People coming into the city would wash their feet in the river giving it the name, Paondhoi.

While crores of rupees have been allocated for cleaning up Ganga, the river continues to flow filthy. Posted on 19 Sep, 2018 12:06 PM

As the Ganga emerges from the glaciers and glides along the foothills of the mighty Himalayas through the towns and cities with their sprawling ghats, engineered embankments, hydroelectric dams, and interrupted flows at barrages, the icy chilliness of its waters is lost.

River Mutha, the pride of Pune, lovingly called 'Muthai' or 'mother Mutha', is dying a slow death, thanks to the rapidly urbanising city which is depositing huge amounts of untreated sewage and dirt in its water. The pollution of the river is consistently rising.

Toxins on our plate
There is a need for better regulation and monitoring to bring toxin-free food to the Indian market. Posted on 08 Aug, 2018 03:45 PM

“The recent scare due to the detection of formalin-laced fish across Goa, Kerala, Assam, Manipur, Nagaland and Meghalaya points to a link between water quality and food safety. Fish traders find it cost-effective to use formalin, a carcinogen, instead of ice to prevent the decomposition of fish during transportation to distant markets.

The quality of food products and their safety are mostly decided at the primary production stage itself which is unregulated. (Image: Masahiro Ihara, Flickr Commons CC BY 2.0)

Treating sewage with plants
Neknampur lake serves as a fitting example of how low cost but effective natural techniques can be used to clean city lakes that are choking with pollutants. Posted on 17 Apr, 2018 04:56 PM

A radical new method is fast emerging as an effective and sustainable solution to increasing pollution in urban lakes. Called floating treatment wetlands (FTW), they are artificial islands with plants that stay afloat on the lake. The plants clean the lake through hydroponics system, resulting in a cleaner, beautiful lake and an improved habitat for creatures that depend on it.
