National Mission for Clean Ganga (NMCG) progress report

  • The National Mission for Clean Ganga (NMCG) intends to clean the Ganga River by processing sewage from five main states using sewage treatment plants (STPs) and sewerage networks.
  • NMCG has reached 20% sewage treatment capacity in seven years, with a target of 60% by December 2026.

SignificanceAddresses environmental, social, and cultural issues while guaranteeing long-term water quality

Capacity for Sewage Treatment Now and in the Future

  • Currently, NMCG handles approximately 20% of the sewage generated in the Ganga river basin.
  • The capacity for treatment is expected to increase to 33% by 2024 and 60% by December 2026.
  • Sewage generation in five states is expected to be 11,765 million litres per day (MLD): Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, and West Bengal.

The Function of NMCG

  • NMCG’s goal is to keep untreated sewage from entering the Ganga River.
  • The prediction of 11,765 MLD includes sewage generated within states but not necessarily flowing into the river.
  • The NMCG plan calls for the construction of a 7,000 MLD sewage treatment capacity by 2026.

Projects and Development

  • STPs and sewage networks account for roughly 80% of the NMCG project.
  • By July 2023, functional STPs will have treated 2,665 MLD, with 1,455 MLD added in the previous fiscal year.
  • Land acquisition concerns and modifications to Detailed Project Reports caused project delays.

Distribution by State

  • Uttarakhand has the most STPs (36), followed by Uttar Pradesh (35) and West Bengal (11).
  • Despite the NMCG’s 20,000 crore budget, in-principle clearance has been obtained for 37,396 crore in projects, with 14,745 crore set aside for infrastructure development by June 2023.

Indicators of Good Water Quality

  • The water quality in Ganga has now reached the “prescribed limits of notified primary bathing water quality.”
  • Nature’s acceptance of river restoration initiatives can be seen in the increased dolphin population (2,000 to 4,000) and the presence of Indian carp in cleaner waterways.
  • To effectively communicate water quality standards, NMCG is developing a water quality index comparable to the air quality index.
