Innovative cleansing of the lake

In the newspapers yesterday (10th Dec 2011), you may have read about BBMP-PNLIT collaborating with a private firm Enzen Water Solutions to clean the water in the lake using a Nano-Nutrient Solution (NNS).

Since it involved using chemicals, a trial run was done in a cement tank in the coconut grove, taking 15,000 litres of water from the dirtiest part of the lake into the tank. A week after treating the water, Enzen introduced 3 kg of Tilepia fish (22 numbers). Not only did the fish thrive but the water itself steadily gained clarity.

The results of the trial were made public in a press conference at the lake on 9th Dec and has generated a great deal of interest as a possible solution to clean our city lakes. Officials from the BBMP, Enzen and PNLIT Trustees addressed the press. News9 is likely to telecast a capsule tonight between 10 and 10.30 p.m. or tomorrow morning.

BBMP may introduce this method to clean the water in a month or so. By purifying the water and increasing the oxygen level, the NNS will control the growth of aquatic weeds and also promote fish life, consequently bringing more birds to our lake. As you can see, we are earnestly working on transforming the lake into an avian habitat.
