Major rivers of your state?

70% of Delhi’s water comes from the Yamuna.
It rises on the slopes of the Bandarpunch massif in the Great Himalayas near Yamunotri in western Uttarakhand.
The Delhi stretch of the Yamuna River is about 22 km from the Wazirabad barrage to the Okhla barrage.
This stretch alone is responsible for 76% of the rivers’ pollution but this stretch is also the primary source of raw water for the capital.
This roughly accounts for 70% of Delhi’s water supply which roughly translates to 57 million people.
Around 90% of wastewater from households pours into the river untreated. The same goes for industrial effluents and sewage that are discharged into the river without being treated.
Only 35% of the total estimated sewage discharge undergoes treatment.
The lead, plaster of Paris (POP) and chrome paints used in making the idols also pollute the water after they are immersed. Not only this, but all the overlooked things like polythene bags, decoration items, metal polishes etc. are also contributing factors.
Nearly ₹6,800 crore was spent over five years, from 2017-21, to clean the Delhi stretch of river Yamuna but the stretch remains polluted and is not even fit for bathing.
Where the Yamuna enters Delhi (Palla), its Biochemical Oxygen Demand (BOD) level is only 2. However, when it exits Delhi (Okhla), the BOD level exceeds 55.
