Sewage treatment
On 25 April 2014, the National Green Tribunal Act (NGA) recommended the government to declare a stretch of the Yamuna in Delhi and Uttar Pradesh as a conservation zone. A report prepared by the Ministry of Environment and Forests (MoEF) panel was submitted to the NGA on the same day. Under the Yamuna Action Plan (YAP-I and YAP-II), pollution cleanup of Yamuna was conducted in line with the biological oxygen demand of Yamuna. Under these two phases, 286 schemes, including 39 sewage treatment plants, were completed in 21 towns of Delhi, Uttar Pradesh, and Haryana at a cost of 1,453.17 crore (14.5 billion rupees). Sewage treatment capacity of 767.25 million litres per day was created through these efforts.
