New Delhi: Officials at Delhi Development Authority’s South Delhi Biodiversity Park have successfully been able to create a constructed wetland using just plants and boulders, which will allow the park to naturally purify 15 to 20 million litres per day (MLD) of raw sewage. The constructed wetland is the first of 12 such wetlands, which will be created in the biodiversity park area that is located in the floodplain underneath the DND Flyway and next to Kalindi Kunj, allowing them to prevent 1,500-2,000 MLD or raw sewage from entering the Yamuna.

A team led by Professor CR Babu, the head of Centre for Environmental Management of Degraded Ecosystems (CEMDE), has been working on the project for several months now and says the design created at the park is unique and has not utilized any artificial materials, such as concrete. The constructed wetland consists of 25 different types of plant species, which naturally purify the water through microbes, before it is released into a larger waterbody.
