Wastewater Treatment – Issues

Inadequate treatment infrastructure

•      Only 26.8% of domestic and 60% of industrial wastewater is treated in India

•      Wastewater management plants in cities have a capacity of approximately 6,000 MM liters per day

•      423 Class I2 cities treat just 29.2% of their wastewater. 499 Class II towns are able to treat just 3.7% of wastewater due to poor treatment infrastructure

•      Delhi, the national capital, treats less than half of the 3,267 MM liters of wastewater it generates every day


Use of untreated wastewater for irrigation

•      Reduction in agricultural production e.g. in Hyderabad, wastewater drawn from the river Musi for irrigation has reduced rice output by 40-50%
