Policy push needed to boost India’s water reuse, says Veolia’s Anne Le Guennec

According to Le Guennec, encouraging industries to transition from freshwater dependence to treated wastewater could significantly ease pressure on freshwater resources. Data from the Central Pollution Control Board shows that India generates over 75,000 million litres per day (MLD) of wastewater, but treatment capacity remains insufficient, creating a large untapped opportunity for reuse. Globally, countries like Israel reuse nearly 85–90% of their wastewater, compared to India’s estimated reuse rate of less than 30%, underlining the scope for improvement.
