Floating wetlands

Karachi, a rapidly urbanizing city, is grappling with severe water pollution in its rivers. To combat this issue and mitigate climate change, a novel approach is being implemented: floating wetlands. These wetlands, covered in Water Lettuce, a fast-growing aquatic plant, will act as natural filters, purifying polluted water and releasing clean oxygen. The dense root system of Water Lettuce traps pollutants, while its leaves provide shade and oxygenate the water. Even during extreme conditions, such as heatwaves, the Water Lettuce has demonstrated remarkable resilience, thriving in polluted waters. By improving water quality and creating a healthier environment, this innovative project aims to enhance the lives of Karachi’s residents.


Karachi, a bustling metropolis, faces significant water pollution issues. To address this challenge and contribute to a greener future, we’ve embarked on a project to implement floating wetlands. These wetlands, covered in climate-resilient plants, will act as natural filters, purifying polluted water and improving air quality. By conducting thorough research and pilot tests, we’ve identified suitable plants and optimal conditions for these floating wetlands. Our goal is to not only clean up the water but also create a more sustainable and resilient urban environment. We believe that by focusing on these 41 polluted drains in Karachi, we can set an example for other cities facing similar challenges. Ultimately, this initiative aims to improve public health, enhance biodiversity, and mitigate the effects of climate change, making Karachi a cleaner, greener, and healthier city for future generations.
