Micro-Interventions Revive Yamuna's Health
3 Apr
Summary
- Delhi adopts data-driven, decentralized strategy for Yamuna rejuvenation.
- Najafgarh drain split into 22 segments for targeted pollution control.
- Efforts include connecting households and managing dairy waste.
Delhi Jal Board (DJB) has initiated a significant two-year roadmap to rejuvenate the Yamuna River, employing a decentralized, data-driven strategy to curb pollution in the Najafgarh drain. This approach focuses on micro-level interventions for precise pollution source identification and management.
The 52-km Najafgarh drain, identified as a major contributor to Yamuna's pollution, has been segmented into 22 areas. Dedicated teams are now monitoring pollution levels monthly in each segment to track contamination sources effectively. This allows for immediate intervention when pollution indicators like biological oxygen demand rise.
DJB's plan includes connecting unsewered households to the sewer network and collaborating with the Municipal Corporation of Delhi to manage waste from dairies. Initiatives like biogas plants and composting are being promoted to divert dairy waste from drains.
While smaller interventions are underway, officials acknowledge that large-scale infrastructure upgrades, such as expanding sewage treatment plants, will require time to show visible results. The flood control department is also tasked with cleaning major drains.
