Chennai MWSSB has begun work to lay pipelines to draw seawater and discharge brine from the upcoming third desalination plant at Nemmeli. The plant will have a capacity to treat 150 million litres of seawater a day (mld).
Over 50% of the construction of seawater intake sump, ultrafiltration, reverse osmosis, and dissolved air flotation, in the plant has been completed so far.
The CMWSSB has laid cofferdams (a structure that enables work to lay pipelines for the desalination plant).
