Nearly six weeks after inaugurating city’s first Tertiary Treatment Reverse Osmosis (TTRO) plant in Kodungaiyur, Chief Minister Edappadi K Palaniswami, on Friday, inaugurated a second plant in Koyambedu which cost the exchequer Rs 486.21 crore. It has the capacity to process 45 million litres of water per day (MLD).
“As industries use treated water, the city will not have to face water shortage even if monsoon fails,” the CM said. Metro Water plans recycle around 20 per cent of total sewage water generated in the city every day. Kodungaiyur TTRO plant also processes 45 MLD of sewage. Speaking at the event, Deputy Chief Minister O Panneerselvam said that before the two TTRO plants were set up, Metro Water was supplying only 36 MLD of treated water to the industries.
A Metrowater official said that the TTRO treated water is pure as its total dissolved solids (TDS) is only 70 units while water up to 500 units is considered fit for drinking.
