Once revered as a sacred river, Delhi’s Yamuna has turned into a toxic drain, foaming with chemicals and choking with untreated sewage. Despite thousands of crores spent on clean-up missions, the 22-km stretch in Delhi remains severely polluted. With a new 2027 revival deadline, the question remains: can the capital truly restore its dying river in time?
Before the 1990s, the Yamuna entered Delhi through Palla with relatively clean water, supporting aquatic life. Green buffers, limited industry, and a natural flow made the river a symbol of purity. However, Delhi’s population boom and unplanned urbanisation quickly overwhelmed this ecosystem. Over time, unchecked sewage and industrial effluents turned this sacred stream into one of India’s most polluted rivers.
Multiple efforts to revive the Yamuna began in the 1990s, starting with the Japan-funded Yamuna Action Plan I. Despite court directives and large budgets, results were poor. Coliform levels exceeded safe limits by millions, and sewage treatment plants underperformed. Later, under YAP II and Namami Gange, crores more were spent—but the river continued to foam, stagnate, and emit a foul stench.
By 2023, a staggering 76% of the Yamuna’s pollution load came from Delhi alone. Religious festivities like Chhath Puja made headlines when devotees were seen standing in toxic foam. While 35 sewage treatment plants existed, most failed to meet pollution norms. Low oxygen levels and phosphates from detergents left the river unfit for aquatic life or public use.
After a BJP-led government took office in Delhi in 2025, a new Yamuna Master Plan was launched, targeting revival by December 2027. Measures include 40 decentralised STPs, retrofitted sewer lines, real-time water quality monitoring, and ₹1,000 crore budget support. Trash skimmers removed 1,300 tonnes of garbage in just 10 days. The plan also includes restoring floodplains and building public walkways to reconnect citizens with the river.
Delhi’s latest Yamuna revival plan is ambitious, combining technology, funding, and public engagement. Yet, past failures remind us that plans alone don’t clean rivers—enforcement, political will, and sustained civic participation are key. If successful, the 2027 mission could set a national example. If not, the Yamuna may continue to foam with toxins, a stark symbol of urban neglect and environmental apathy in India’s capital.
