The two zones require 45 million litres per day (MLD) of water, and receive 38 MLD, of which 28 MLD are supplied from Nemmeli desalination plant and 10 MLD from Veeranam, officials said.  “In the last six months, the Nemmeli plant was shut for maintenance often.

With the Nemmeli desalination plant shut for maintenance, people in parts of Perungudi and Sholinganallur zones haven’t had water supply for nearly a week. They said they are forced to buy water from private suppliers as the plant is being closed every month.
