Metrowater has started drawing 15 million litres a day from 300 wells on agricultural land it has leased in Tiruvallur, Tamarapakkam and Minjur to meet the city’s water needs.

Metrowater managers say the supply situation isn’t too bad with 180 million litres a day piped from Veeranam lake and an equal quantity from the two desalination plants too, but cause for worry is the depletion of the groundwater table in the city.

If needed, more water could be drawn from the wells. Water drawn from these wells is pumped into the Puzhal reservoir. After treatment, the water is piped to Anna Nagar, Kilpauk, Kolathur, Korattur, Ambattur and up to Nungambakkam lake area in the heart of the city, a senior officer said.
