Welcoming Kerala's gesture to supply drinking water to Tamil Nadu, Chief Minister K Palaniswami on Friday said that the neighbouring state had only offered 20 lakh litres when its parched capital city Chennai needed a lot more. "I thank the Kerala Chief Minister, but 2 MLD (million litres per day) water will not be sufficient. We are everyday supplying 525 MLD water (in Chennai) and if 2 MLD water could be given every day, it will be useful for the people," Mr Palaniswami said.
