Delhi government's Yamuna cleaning and sewage treatment initiatives

The topic provides a practical case study on urban infrastructure and environmental management, which is useful as context for questions on water pollution and urban governance, though it is not a major national policy or landmark event.

Notes

  • Delhi government aims to award contracts for 16 new Decentralised Sewage Treatment Plants (DSTPs) by July.
  • Project goal: Enhance sewage treatment capacity to curb pollution in the Yamuna river.
  • Total target capacity for DSTPs is 170 million gallons per day (MGD).
  • Union government directive: Increase total sewage treatment capacity in Delhi to 1,500 MGD by 2028.
  • DSTPs are designed to treat sewage near the source, specifically for unauthorised colonies lacking sewer networks.
  • Current system relies on 37 large STPs requiring extensive transport networks; DSTPs reduce the need for long-distance sewage conveyance.
  • Project timeline: Completion of 29 planned DSTPs by January 2028 and associated sewer networks by June 2028.
  • Major implementation challenges include land availability and coordination between central and state authorities.
