Amma Kudineer

Amma Kudineer (meaning "Mother drinking-water" in Tamil language) is a mineral water production and distribution project run by the Government of Tamil Nadu in India.
About the scheme.
The project was formally launched on 15 September 2013 by the Chief Minister Jayalalithaa, on the 105th birth anniversary of former Tamil Nadu Chief Minister C. N. Annadurai. 
The project involves production and packaging of mineral water in one litre plastic bottles, and selling them in long-distance running state-owned buses and in bus stations. The price has been fixed at ₹10 per bottle. The project is intended to make purified water available to people of all strata, at a reasonable cost.
The Indian Railways has been undertaken a similar scheme under the name "Rail neer" for some time now, with its one-litre bottles priced at ₹15, while private companies sell 1-litre bottles at higher prices.
The scheme is run by the Tamil Nadu State Transport Corporation, with a production plant in Gummidipoondi in Thiruvallur district, on a 55-acre land that belongs to the Institute of Road Transport (IRT), a subsidiary of the Tamil Nadu State Transport Corporation. The plant has the capacity to produce 3 lakh liters of purified water per day. The total dissolved solids (TDS) in the water is reported to be below 50 parts per million (ppm), as compared to a requirement of below 150 ppm in water from lakes and in rainwaters.
