Sahibi Nadi: How a river was killed

In his book, The Biology of Belief, American biologist Bruce Lipton narrates a peculiar tree killing technique practised by the tribes of the Solomon Islands. The tribals encircle a tree and curse it relentlessly. Apparently, the tree eventually dies.

Here, Lipton seeks to highlight the power of the subconscious mind to convert positive or negative sentiments into self-fulfilling prophesies. You may take Lipton's story with a pinch of salt. But, it appears to be working in case of our commons (water bodies, grazing lands, sacred groves, etc).

Nala, a Hindi word that once meant a channel for carrying stormwater as well as rivulet or stream, has degenerated to signify only a dirty channel of water. Drain, that once signified a channel to drain something, especially rainwater, has come to mean a channel carrying wastewater.

While it may be difficult to pinpoint the exact moment these terms underwent degeneration, it seems to coincide with urbanisation, which came at a cost to our commons. Their value was lost on the community, with hassle-free availability of finite resources through utilities, predicating a disconnect with our natural heritage.

A particularly poignant story playing out right before our indifferent eyes is that of the Sahibi nadi (river) aka Sahabi, Sahbi or Sabi. At one time, this river might have held perennial flow as is evident by the presence of several Indus Valley Civilization sites on its banks as well as those of its tributaries, the Sota, Krishnavati and Dohan.

Scholars have identified the Sahibi river with the Drishadvati river of the Vedic period. We have willfully overlooked the rich heritage the nadi represents. Presently, this ephemeral river rises phoenix-like from some of the most arid regions of India. It flows from the Saiwar hills in Sikar district in Rajasthan.

It goes forth, collecting the waters of almost 100 tributaries. In its upper reaches, the Sahibi drains parts of Rajasthan like Alwar and the southern districts of Haryana like Rewari. In its lower reaches, it receives the waters of the Indori nala near Pataudi and Badshah nala further north. Beyond Pataudi to the north, the nadi extends in two directions: north-west and north. The latter course used to join the Yamuna via the Najafgarh jheel (lake) and drain number 6. The former used to link it with the Jhajjar depression and drain number 8, which also joins the Yamuna. Downstream of the Najafgarh jheel on the Delhi side, the nadi used to drain into the Yamuna just before Wazirabad through a channel now famously known as the Najafgarh drain. The Najafgarh drain gets its name from the Najafgarh jheel.

Nothing remains of the fort today, except for the Najafgarh village, which is fast getting urbanised. Najaf Khan's tomb lies right next to the Safdarjung flyover, around a kilometre each from Safdarjung's tomb and the Lodhi Gardens as well as the hyperactive INA market.

The Najafgarh drain on the Delhi side is a creation of a more recent time wherein the government of the North-West Province in 1865 excavated the irregular channel of Sahibi (An antique map of 1807 of the Environs of Delhi depicts the channel of Sahibi nadi as Sabee nullah — a series of jheels connected through small streams draining into the Yamuna) from the eastern end of the jheel to the Yamuna. This was done to drain the jheel and create more cultivable land.

Owing to its long passage through arid and sandy country, the Sahibi flows with strength only during the rainy season. Heavy floods were recorded in 1845, 1873, 1917, 1930, 1933, 1960, 1963, 1972 and 1977.

To check the entry of Sahibi waters in Delhi, a regulator was constructed at Dhansa in 1964, along with a bund on the Delhi side of the jheel. Again, in response to the great flood in 1977 that affected far-off places like Janakpuri in Delhi, the Masani barrage was constructed on the Delhi-Jaipur highway near Masani village in Rewari.

Several smaller dams have also been constructed throughout the hills of Rajasthan to store rainwater. The construction of dams has restricted the flow of water in the nadi and it is now rare for water overflow from monsoon rains to reach up to the Masani barrage.

The construction of the barrage not only sealed the fate of the Sahibi but also that of Najafgarh jheel, along with the Najafgarh drain. One of the fundamental rights of a river is to flow. Another is to receive tribute from its tributaries while simultaneously paying tribute to a larger river.

Killing the Sahibi prematurely at Masani barrage and not allowing it to meet Yamuna, is a violation of its fundamental rights. It is amazing that nature has a way to cling on despite humanity's best efforts to undermine or destroy it. Several important wetlands lie in a series along the current and paleochannels of the Sahibi river.

While legislation is in place to protect rivers, the wheels turn ever so slowly. The River Ganga (Rejuvenation, Protection and Management) Authorities Order, 2016 is a document with an ambitious scope. It ordains applicability to the states comprising the Ganga basin, including Haryana and the National capital Territory of Delhi. It brings the Ganga and all its tributaries (which includes the Yamuna as well as its tributaries such as the Sahibi nadi) and their respective flood plains under its ambit. It explicitly prohibits construction of any sort in such flood plains. However, this order is being observed in its breaches particularly on the Haryana side of the Sahibi and its wetlands in Gurugram.

Meanwhile, the Najafgarh drain is the largest contributor of sewage (55-60 per cent) to the Yamuna in Delhi, which, in turn, has been declared, alarmingly, dead for all practical purposes. The pollutants from the Najafgarh jheel and the drain are leaching into the soil and contaminating the aquifers.

However, it wasn't always like this. Sohail Hashmi talks about days that don't go back very far. Upto the 1960s, the drain had clean water to sustain fish and people used to catch fish in it.

Hashmi particularly narrates an event of the early 1960s, when a vanaspati (vegetable oil) factory at Zakhira accidently discharged large amounts of vanaspati into the nearby Najafgarh drain.

Since it was winter at the time, the vanaspati solidified in the drain water. The water was so clean at that time that people in the surrounding areas collected the vanaspati from the drain for use in their homes.

The Sahibi's story is the story of all rivers in India. They have been reduced to the latter meaning of the terms nala and drain, especially in urban areas. This is true for not just water bodies but for all commons.
