The Yamuna Crisis – Beyond Politics

About The Yamuna Crisis – Beyond Politics:

• • The issue of the Yamuna river’s contamination has turned into a political controversy, with Ex. Delhi Chief Minister accusing Haryana of polluting Delhi’s water supply.
  • As legal battles ensue and the Election Commission intervenes, it is essential to examine the health of the Yamuna beyond political rhetoric.
• Key Issues Related to the Yamuna: Three major concerns regarding the Yamuna and Delhi’s water supply are:
  • Drinking Water Supply
  • Pollution
  • Environmental Flow
• Drinking Water Supply:
  • The supply challenges:
    • Delhi’s drinking water comes primarily from Haryana, with major inlets at Wazirabad Barrage, which depends on releases from Haryana’s Hathni Kund Barrage.
    • Delhi’s treatment plants (Wazirabad, Chandrawal, Okhla, Haiderpur, and Bawana) rely entirely on Haryana’s water supply.
    • Water shortages arise during lean seasons, forcing plant shutdowns and leading to supply of untreatable water and water scarcity crisis.
  • The ammonia issue in Delhi’s water:
    • Ammonia, a colorless gas with a sharp odor, dissolves in water and is widely used in industries, fertilizers, and cleaning agents.
    • It enters water bodies through industrial effluents, agricultural runoff, and untreated sewage.
    • High ammonia levels in the Yamuna, caused by industrial discharge from Panipat and Sonipat and sewage from colonies, impact water quality by reducing dissolved oxygen.
    • Water treatment plants in Delhi cannot process ammonia levels above 1 part per million (ppm), leading to disruptions in the capital’s water supply.
  • How is ammonia-laden water treated?
    • The Delhi Jal Board (DJB) uses chlorine to neutralize ammonia in water treatment plants.
    • Approximately 11.5 kg of chlorine is needed per litre of water per hour to counteract one ppm of ammonical nitrogen.
    • Efficiency of treatment plants drops in winter due to increased ammonia levels.
  • Government actions on ammonia contamination:
    • A long-term solution has yet to be implemented by Delhi and Haryana governments.
    • In March 2023, Delhi proposed an in-situ ammonia treatment plant at Wazirabad, but it remains under development.
    • Haryana has not completed laying pipelines to prevent pollutant mixing in the river.
  • Pollution – A Lingering Threat:
    • Apart from ammonia contamination, multiple factors contribute to Yamuna’s pollution:
      • Unregulated sewage discharge: Sewage flows into stormwater drains due to incomplete sewer connections in unauthorized colonies.
      • Industrial waste: Unlicensed household industries discharge untreated effluents.
      • Solid waste dumping: Illegal dumping continues despite regulations.
    • Key findings and unfulfilled commitments:
      • The National Green Tribunal’s Yamuna Monitoring Committee (YMC) (2018–2021) identified 16 major polluters, including Delhi Jal Board and authorities from Haryana and Uttar Pradesh.
      • The Najafgarh, Supplementary, and Shahdara drains are major contributors to pollution.
      • Haryana had committed to setting up Sewage Treatment Plants (STPs) but failed to implement them fully.
      • Delhi’s Interceptor Project aimed at treating sewage before discharge has seen partial success but remains ineffective due to incomplete execution.
    • Environmental Flow – The Need for Sustained Water Levels:
      • The National Institute of Hydrology (NIH) study highlighted that excessive water withdrawals upstream drastically reduce Yamuna’s flow through Delhi.
      • Reduced flow increases pollutant concentration and disrupts aquatic life.
      • The YMC recommended revisiting the 1994 water-sharing agreement between Delhi, Haryana, Himachal Pradesh, Rajasthan, and Uttar Pradesh for fairer water distribution.
      • Regulatory interventionby the central government or courts is necessary to ensure a sustainable environmental flow.
    • Conclusion – The Need for Political Will and Action:
      • While reports and recommendations exist, implementation remains weak due to political and bureaucratic inertia.
      • Unless policymakers, engineers, and administrators take decisive action, neither political promises nor manifestos will have any real impact.

Citizens must recognize the gravity of the crisis and demand accountability to ensure the Yamuna’s restoration and sustainable management.
