Bellandur Lake – The Toxic Paradise

SIX things that make you wonder how amazing the Bellandur Lake was before it turned toxic:

1. Located in the suburbs of Bellandur in south-east Bengaluru and spanning over 726 acres in size, Bellandur Lake is the largest lake in the city.

2. The lake was prominently known to be a hotspot for wildlife. It used to be a safe haven for kingfishers, parrots, parakeets, wood pigeons, kites, king cobras, rat snakes and monitor lizards.

3. Bellandur Lake was once the source of revenue for almost 18 nearby villages. Residents of Bellandur village recall the good times when the lake was full and the land next to it fertile, until the 1970’s. Paddy, Cauliflower, and Tomato used to be cultivated in abundance here.

4. Over 400 fishing families used to earn their revenue from the lake. Imagine the economic loss and perils these families have faced due to the lake’s dying ecosystem.

5. ‘Theppotsavam’, an Annual Boat festival used to be celebrated on this lake.

6. The lake used to be a landing channel for Walrus Seaplane during World War 2.

 

The Current Condition:

Sadly, this beautiful lake is now known for being one of the most highly polluted lakes in India. As per some sources, the pollution in the lake is due to untreated sewage water entering the lake through various inlets. As a result, the Pollution Control Board is adopting stringent measures to enforce the use of efficient treatment plants in the buildings/factories that dispose wastewater to the lake.

In the recent years, one common sight for the locals has been the formation of froth at the lakes. Froth formation was first seen in the 1980’s and rapid increase in urbanization has greatly resulted in its exponential growth. Experts have confirmed that the froth formation is a result of toxic factory waste and the untreated sewage waste water present in the lake. The froth contains cadmium, phosphorus, and several other poisonous substances. The foul-smelling foam has resulted in several effects such as skin rashes, eye irritations, headaches, and dizziness. It is also a nuisance, especially during rainy and windy days, when it floats onto nearby roadways, impairing visibility.

Last year in 2015 the froth on the lake had caught fire. Residents often complain that the froth spills onto the road many times and it is heckling them as they are even unable to walk past that stretch, leave alone drive. The civic authorities often use sprinklers to control the froth level which solves the problem on a temporary basis but a permanent solution for this problem hasn’t been thought through.

Can we revive the lake?

Can we work for a better tomorrow?
