Yamuna River: Why Delhi’s Lifeline Stays Polluted and Dying Regardless of Successive Authorities’s Cleanup Guarantees

The Yamuna occupied centre stage within the campaigning through the current Meeting election in Delhi. All of the events known as consideration to the acute ranges of air pollution within the river, lamenting that town’s lifeline had become a darkish, poisonous stream. They blamed one another for the issue, with every get together making acquainted guarantees to scrub it.

Traditionally, the Yamuna was by no means Delhi’s water line. Satirically, its situation started to worsen after it turned town’s supply of ingesting water.

In keeping with the heritage and conservation activist Sohail Hashmi, not one of the seven capital cities that got here up in medieval Delhi trusted the river for ingesting water. Stepwells and wells supplied the useful resource. The truth is, it was believed that the river water in Delhi was noxious, and this was maybe why Ferozeshah Tughlaq started digging a canal to deliver the river’s water from Hisar in Haryana to Firozabad, his capital. The mission was later accomplished by the Mughal Emperor Shah Jahan, and the canal flowed by way of the Purple Fort and Chandni Chowk. Nonetheless, folks continued to depend upon wells for his or her ingesting water.

“The water within the Yamuna in Delhi was not believed to be potable. It was not used for ingesting however just for different functions corresponding to irrigation, fishing, or bathing. In Delhi, the Yamuna flows over a rock mattress of quartz. There may be mica and silica in quartz. The folks at the moment wouldn’t have recognized this, however they might have observed that those that drank the water suffered from illnesses,” mentioned Hashmi.

In keeping with Hashmi, the Yamuna in Delhi was tapped for ingesting water solely round 1881, when the British sank wells into the riverbed. In 1890, the British launched the sewerage system, and untreated sewage started to be pumped into the river downstream of the Chandrawal waterworks that supplied ingesting water. Thus started the air pollution of the Yamuna. Whereas it got here to be described as Delhi’s lifeline, it was now a useless river, extremely poisonous, and incapable of supporting even aquatic life because it flows by way of the capital.

Air pollution and politics

Air pollution of the Yamuna has all the time been a outstanding difficulty in Delhi’s politics. In election manifestos, political events pledge to scrub the river, and successive governments have unveiled plans to rid the river of air pollution. Shortly after the brand new Chief Minister, Rekha Gupta, and her Cupboard colleagues have been sworn in on February 20, they carried out an aarti on the banks of the river. It was a symbolic occasion, excessive on optics and consistent with the federal government’s vow to scrub the Yamuna.

Just a few days earlier, Lt Governor Vinai Kumar Saxena had introduced a plan to scrub the river in three years. The Yamuna additionally figured in a giant manner in Prime Minister Narendra Modi’s speech on February 8 to mark the BJP’s victory in Delhi. He raised the slogan, “Yamuna Maiya Ki Jai” (Hail Mom Yamuna) and mentioned he had taken a pledge to make the river the pleasure of Delhi.

In 2015, former Chief Minister Arvind Kejriwal too had carried out Yamuna aarti quickly after taking cost. He too had declared that his authorities would clear up the river inside 5 years. Through the marketing campaign for the current election, he accepted his failure to fulfil the promise.

The Yamuna in city Delhi is 22 km lengthy. That’s solely 2 per cent of the river’s complete size, however it’s on this tiny stretch that over 80 per cent of the air pollution occurs. Untreated sewage and industrial effluents are dumped into the river throughout its passage by way of the capital, making it darkish, poisonous, and foul smelling.

The extent of air pollution

In keeping with a January 2025 report by the Delhi Air pollution Management Committee, the biochemical oxygen demand of the river is 70 mg/l, whereas it needs to be 3 mg/l or much less. The faecal coliform stage of the water is 84,00,000 MPN/100 ml, whereas it shouldn’t exceed 2,500 models, and the fascinating quantity is 500. The dissolved oxygen stage is 0, whereas it needs to be greater than 5 mg/l. With no dissolved oxygen, the river is biologically useless.

In keeping with a Parliamentary Standing Committee on Water Assets report launched on February 6, 2024, and titled Evaluate of Higher Yamuna River Cleansing Tasks as much as Delhi and Riverbed Administration in Delhi, of 33 areas monitored between 2021 and 2023, the water high quality in 23 areas didn’t adjust to the first standards required for tub water. Excessive ranges of metals corresponding to lead, copper, and zinc have been additionally present in varied sludge samples, which poses extreme well being hazards.

Successive governments in Delhi and on the Centre have made and initiated plans to scrub the Yamuna, spending 1000’s of crores of rupees. In keeping with the Surroundings Division of the Delhi authorities, Rs.6,856.91 crore was spent over 5 years from 2017 to 2021 to scrub the Yamuna. Greater than Rs.1,500 crore was spent as a part of the Yamuna Motion Plans (YAP) I and II, carried out by the Centre between 1993 and 2013. YAP III, launched in 2012 at an estimated value of Rs.1,656 crore, is at present underway.

Beneath the Namami Gange Venture, between 2015 and 2022, 26 initiatives have been sanctioned at a price of Rs.4,438.39 crore for creating or refurbishing sewage remedy crops (STPs) on the Yamuna basin, overlaying Himachal Pradesh, Haryana, Delhi, and Uttar Pradesh.

Actions and outcomes

In keeping with a progress report of the Delhi Air pollution Management Committee (DPCC) submitted to the Nationwide Inexperienced Tribunal (NGT) in February 2024, Delhi has 37 STPs, which deal with round 70 per cent of the wastewater generated within the metropolis. The amount of sewage generated in 2024 was 3,600 million litres per day (MLD), the put in capability of the STPs was 3,033 MLD, and the utilisation of the STPs was 2,574 MLD. Nonetheless, the DPCC additionally discovered that solely 14 of the 37 STPs met the prescribed requirements.

The Parliamentary Standing Committee report on water sources noticed that solely 17 of the 28 authorised industrial clusters in Delhi are related to effluent remedy crops, and solely 32 per cent of their capability is utilised.

That the Yamuna in Delhi is at its most polluted at current is proof sufficient of the ineffectiveness of the steps taken by successive governments and their failure to scrub the river regardless of the massive quantities of cash spent.

The NGT has in varied orders over the previous decade expressed anguish over the federal government’s failing to implement its directives with regard to cleansing the Yamuna. These directives pertain to the capability of STPs and the standard of handled wastewater, areas which have up to now not been lined by the sewerage community, measures for the reuse of handled wastewater, and rejuvenation and restoration of the Yamuna floodplain and related wetlands.

Rubbish in, rubbish out

In keeping with Susmita Sengupta, senior programme supervisor, Water and Wastewater, Centre for Science and Surroundings, the efforts is not going to succeed until the federal government accepts that almost all of the untreated sewage going into the river originates from unauthorised colonies and takes steps to cope with it.

“An unlimited inhabitants of Delhi lives in colonies that aren’t related to the sewerage community. The bogs in these habitations are both immediately related to drains that vacant into the river, or the waste from the bogs is carried by tankers that then dump it into the drains. So, we’ve a scenario the place handled water from the STPs is being launched into the identical channels that obtain untreated waste. This successfully negates the associated fee and energy of cleansing,” mentioned Sengupta.

She mentioned the federal government ought to give attention to guaranteeing that every one desludging tankers are registered and GPS-tagged in order that their motion is monitored. They shouldn’t be allowed to dump untreated sewage into the drains however take it to remedy crops.

What the Yamuna in Delhi desperately wants, based on Himanshu Thakkar of South Asia Community on Dams, Rivers and Individuals, is extra water flowing into it. “For a lot of the yr, the river throughout its Delhi stint simply doesn’t get sufficient water. The federal government has to make sure that sufficient contemporary water flows into the Yamuna downstream from the Wazirabad barrage, the place the river enters Delhi.”

Thakkar mentioned the federal government would even have to make sure that all handled wastewater is reused and never pumped again into the river. He additionally known as for rainwater harvesting and rejuvenation of native water our bodies. These efforts, he mentioned, would scale back the demand for contemporary water from the Yamuna, leaving extra water in it.

Want for built-in water administration

“There are various items to the Yamuna puzzle. A fundamental requirement to having a holistic method to cleansing the river is a Delhi water coverage. It would take a complete take a look at the scenario and supply a highway map to scrub the river,” Thakkar mentioned.

Lt Governor Saxena has introduced a four-pronged plan to scrub the Yamuna inside three years: eradicating trash and silt from the river; cleansing drains that vacant into the river; a each day watch on the capability and output of STPs; and a time-bound plan for development of recent remedy crops.

Whereas the Lt Governor’s initiatives are a step in the suitable route, based on S.Okay. Sarkar, Distinguished Fellow at The Vitality and Assets Institute and former Secretary, Union Ministry of Water Assets, it’s tough to offer a time-frame to realize the specified final result.“Given the a number of elements concerned, setting a time restrict for decision of assorted pending points and conforming to the air pollution requirements could be very tough,” he mentioned.

In keeping with Sarkar, a number of businesses are investigating completely different features of the Yamuna’s air pollution, and a coordinated mechanism with a transparent, actionable agenda is required. He mentioned an impartial regulatory authority ought to oversee built-in water administration, and emphasised that the Centre should play a job in general monitoring of the cleansing efforts.

“The Centre’s function in general monitoring for enchancment of water high quality of rivers in session and cooperation with States has been recognised, and varied remedial measures have been initiated. The Nationwide Mission for Clear Ganga is accountable for cleansing the Ganga. An analogous step could also be taken for the Yamuna as effectively,” Sarkar mentioned.

Hashmi mentioned it was excessive time immediately’s leaders went past politicking over the river and made a honest effort to revive it. “This could not simply be about getting votes and successful elections. The lives of hundreds of thousands of persons are concerned. It’s about our future generations,” he mentioned.
