NEW DELHI: The water level in the Yamuna in Delhi may have dropped below the warning mark, but the situation is being monitored as the IMD predicted widespread rainfall in the upper catchments of the river, according to officials.

Since the low-lying areas of Delhi near the river prone to flooding have been heavily affected, as the water level has exceeded the danger mark, Delhi Jal Board officials shared that the excess water from Yamuna rain was diverted to a new man-made reservoir. lake in Bawana.

The lake is 3 km long and 20 m wide and is a part of the old Bawana outflow drain flooded by the Delhi government’s irrigation department. According to officials, the water will recharge groundwater that can be extracted during peak summers to increase drinking water. In yet another case, excess rainwater from Yamuna will be diverted to Lake Palla – created by the Delhi government on 26 acres in the area.

This lake has already recharged over 1,400 million gallons of water in the past 17 days. Officials shared that the lake is full of flood water from the river. “The water has a TDS above 100 which is enough for 1.25 lakh homes. It is expected to improve groundwater levels by 2-3 meters,” an official said.

This ‘city of lakes’ project was launched in 2018 to increase water supply by recharging groundwater and recycling treated wastewater to meet Delhi’s water demand of 1,140 million gallons (MGD) per day. The current supply of 940 MGD is lower than the demand of 200 MGD. The establishment of new groundwater recharge reservoirs and the rejuvenation of existing lakes was the motive for the project.

It was in December 2018, when Chief Minister Arvind Kejriwal announced this proposal of the ‘City Lake’ project by approving Rs 376 crore for the rejuvenation of 159 lakes in Delhi and Rs 77 crore for the creation of two mega lakes in Rohini and Nilothi.

Yamuna levels are falling

Meanwhile, on Wednesday, the water level in Delhi’s Yamuna fell below the warning level but the situation is being monitored as the IMD predicted widespread rainfall, officials said on Thursday. The Delhi government’s flood control room said the water level in the river fell from 204.89 meters at 7 a.m. Wednesday to 204.32 meters at 6 p.m. Thursday.

The river had crossed the danger mark of 205.33 meters last Friday, prompting authorities to evacuate around 7,000 people from low-lying areas. The water level had dropped below the alert level on Monday. and stood at 203.96 meters.
