Dhruvansh, an NGO, chose the World Wetland Day to introduce a "floating island" in Neknampur Lake.
Neknampur Lake in Hyderabad is home to hundreds of species of birds, plants, mammals, and reptiles. However, due to rapid urbanisation, it has become a victim of garbage and sewage dumping, which has reduced the once beautiful lake into a polluted and sewage-filled water body.
But this is set to change. Dhruvansh, a voluntary organisation, which works for the protection of water bodies, has taken the initiative to clean up this lake and its surroundings to bring the lake, back to life.
Over the years, the NGO has been campaigning against dumping garbage in the lake and restoring the tree coverage around it. Now, they have decided to work towards purifying the water, in a natural way!
February 2nd is observed as World Wetland Day. The organisation chose this day to introduce a “floating island” in Neknampur Lake.
This island is an artificial platform holding wetland plants, which will help in the purification of lake water.
The 2,500 sq ft platform has been designed using styrofoam, bamboo, gunny bags, coir etc. and will act as a base around 3000 plants including cattails, bulrush, citronella, hibiscus, fountain grass, flowering herbs, and ashwagandha.
The plants were selected after a lot of consideration. This combination is said to be mosquito repellent while also helping in the cleaning of water and increasing the biodiversity of the lake.
This floating island will be multi-layered and installed close to the inlet of the lake.
The first layer, which already exists in the lake is of floating weed. The second layer will be of Typha and phragmites. More layers will be introduced, shortly.
Madhulika Choudhary, who works with Dhruvansh spoke to The Hindu about this initiative. She explained that when the water passes through all the layers, it will get filtered, eventually resulting in optimum fresh water.
The island will also reduce the growth of algae by restricting sun rays from seeping through. She said that the lake would eventually go back to being an ideal habitat for birds and other animals.
