If yes, provide details of its coverage and implementation. • Yes, zero liquid discharge is one of the main focus areas among all environment related initiatives. No water goes out from the Company‘s site boundary untreated except rainwater through dedicated storm water drains. • Most of the plants have rainwater recharging pits for injecting rainwater into deep aquifers. • Though the Company relies more heavily on freshwater, recycled water is, and will continue to be, important for the Company to secure enough water to manufacture vehicles and parts. The Company recycles 44% of fresh water through waste water recycling plants. • Domestic wastewater is recycled through STP (sewage treatment plant) and process wastewater through ETP (effluent treatment plant). Each STP and ETP treatment plants have got 3 levels of treatment i.e., Primary, Secondary and Tertiary. In primary treatment through HRSCC (high-rate solid contact clarifier) all suspended solids are removed. In secondary treatment, through MBBR technology, BOD +COD levels are controlled well below the permissible limit. In tertiary treatment, through Carbon, sand filtration and disinfection units (UV/chlorination) bacteria and viruses are removed. • A portion of recycled water is further treated in reverse osmosis plant (tomake it compatible for process and cooling requirement) and the remaining portion of treated water goes into gardening to the existing green belt created within operations boundary. 5.
