The Delhi government's pilot project to recharge groundwater at Palla has recorded the highest rise of up to 2.5 metres in the groundwater level in its third and final year on the back of a record-breaking rainfall this monsoon, officials said on Tuesday.
The groundwater level in the area -- on the northern outskirts of the capital near the Delhi-Haryana border -- had risen up to 1.3 metres in 2019 and up to 2 metres in 2020, the officer said.
''The three-year pilot project which involved retaining excess Yamuna water in shallow reservoirs on the floodplains during the monsoon season has been completed. Overall, it has yielded very good results,'' an official told PTI.
''We have recorded an increase of 0.5 to 2.5 metres in groundwater levels this year, the highest in the entire project period. Certainly, the record rainfall has a major role to play,'' the official said.
According to the official, the project will be scaled up based on the recommendations of all stakeholders, including the Central Water Commission, Upper Yamuna River Board, Central Ground Water Board, Delhi Pollution Control Committee, Central Pollution Control Board.
While gram sabhas owned 10 acres of this land, the government had acquired 30 acres from farmers on a three-year lease.
The government then created a 25-acre pond on the floodplains of the Yamuna to retain floodwater in the monsoon season and installed 33 piezometers to ascertain the rise in groundwater levels.
