First TTRO plant to be functional in two weeks

According to a Metro Water official, the plant would be operational in 10 to 15 days and they are waiting for government’s approval to inaugurate the plant. “During a recent meeting with the representatives of the industries in north Chennai, we discussed the tariff. They have proposed a tariff and the final decision will be made in the next board meeting,” the official said.

The water manager commenced the construction of the TTRO plant in Kodungaiyur with treating capacity of 45 MLD (million litres per day) in 2017. Works are ongoing for another TTRO plant with a capacity of 45 MLD in Koyambedu. Kodungaiyur TTRO plant would be the first plant in the city to be inaugurated by Metro Water that would supply tertiary treated water.

The official added that they have secondary treatment plants in Koyambedu and Kodungaiyur. Secondary treated water from Koyambedu is being sold to SIDCO, who, in turn, supplies the grey water to industries in Sriperumbudur, Oragadam and other parts. Secondary treated grey water from Kodungaiyur is being sold directly to north Chennai industries.

The Metro Water had also completed pipe laying works from Kodungaiyur to one side of Ennore Creek and water manager could supply TTRO water to industries in the region. The total length of pipelines proposed is around 28 km and the construction of the plant (including pipe laying) was taken up at a cost of Rs 255 crore.

“We supply 1,000 litres of freshwater to industries at Rs 132 per kilolitre and secondary treated water is being sold at Rs 18 per kilolitre. As we did not have TTRO plants earlier, we have to fix the tariff. The tariff would be less than Rs 132 per kilolitre in an effort to encourage industries to use treated water,” the official explained.
