This is the case study of the restoration of the hyper-eutrophic Pushkar lake in India, via CanadianPond.ca’s ¾” micro bubble tubing following the fish kill of September 2008. This case study was provided by our client Randhawa Brosons Enterprises whose project it was.
Pushkar is a small town of about 14,000 people. The total size of the Pushkar Lake is 4.5 hectares, and was about 2 meters in water depth until reaching the start of the 1 – 2 meters of benthic muck in 2008.
Pushkar Lake is one of the most sacred lakes of the Hindu Religion. Pushkar Lake finds mention on coins as early as the 4th century BC.
Being that Pushkar is one of the oldest currently inhabited cities in India, it is safe to reason that organic offerings have been made into the lake for thousands of years. Thus, the solution had to be engineered to deal with over a meter of organic benthic material that had accumulated over centuries, without stirring it. If stirred it would have drastically reduced the already poor water quality.
To create a solution that would dramatically increase the Dissolved Oxygen while not churning the benthic material at the bottom of the lake, 600’ of CanadianPond’s ¾ inch micro bubble tubing was used as the main technology.
Post Aeration, we received no reports of the usual people falling ill after drinking the water or bathing in the lake. More so, the visibility of the water cleared up dramatically after a few months, to where one could see the sandy bottom; whereas, before aeration one could not see an inch into the water due to pollution and cyanobacteria. The local people, priest, pilgrims, and
tourist all enjoyed the newly aerated Pushkar Lake, as it did not smell of sewage, nor did it smell anaerobic digestion as clearly stated in the appreciation letters.
