Wetland system to handle excess sewage at Jakkur Lake in Bengaluru

What used to enter Jakkur Lake as untreated sewage, turning parts of the water black, foul-smelling, and unfit for aquatic life, is now being cleaned through a wetland system, designed to treat excess wastewater that existing infrastructure cannot handle.

The change was made as the lake, despite having a Sewage Treatment Plant (STP), continued to receive ‘additional’ untreated sewage, especially through one of the three inlets — the northern inlet. With no immediate scope to expand the STP, North Corporation Commissioner Pommala Sunil Kumar told The Hindu that they have diverted this excess sewage into a wetland that treats the water in stages.
