GANGA CLEANING (update)

30th November 2018
============
Sisamau Nala closed forever
Discharge of nearly 140m litres of sewage from Sisamau Nala to the Ganga river was stopped and diverted to the STP in Jajmou, Kanpur. This nala was the single biggest contributor to Ganga pollution. Dealing with the residual 60m litre took some time. Pumps were used to overcome with the fast-flowing channel of sewage.

Yamuna et al projects approved
10 projects (Rs 1,570cr) for Ganga tributaries were sanctioned (on 25/11/2018). Sewage drains will be blocked and diverted to STPs, etc. A comprehensive scheme was laid out for Agra. Details are mentioned here:

============
Ganga water is now good enough to support aquatic life
Regular monitoring (at 20 locations on Ganga & 6 tributaries), by independent agencies like ISRO, shows that Ganga water has changed for the better. Dissolved O2 levels have improved & water pH is healthy. This is attributed to the closure of large sewer drains in Kanpur (see above article) and the success in controlling industrial effluents (esp from Kanpur tanneries).

UP Pollution Control Board (UPPCB) officer confirmed these findings. He says O2 levels above and below the former blackspots prove that Ganga cleaning projects are effectively curbing pollution. He also says: “The river water has now become friendly for marine life. They are meeting two ideal water conditions for supporting marine life: that pH level is between 6.5 to 8.5 and dissolved oxygen level is above 2.5 to 3mg/ltr".
