The construction of a 25-acre reservoir to store floodwater from the Yamuna during the monsoon, being built on the floodplains, has been delayed due to the recent flood.

The shallow reservoir to recharge the groundwater was supposed to be completed by August 20. “We had dug around 17 acres. We cannot dig the rest of the area as the flood has made it inaccessible for machines,” an official privy to the development told The Hindu.

On August 9, the work on the pilot project, which is a pet scheme of Chief Minister Arvind Kejriwal, was launched by him and Union Jal Shakti Minister Gajendra Singh Shekhawat.

Officials said it will now take at least two more weeks to complete the project and thus less time will remain for testing out the project this monsoon. It will take about one week for the area to dry and another week to complete the work.

“If there was no flood till August 20, we would have completed the work. But we are hoping that we will complete it soon. There will be one flood cycle in September for us to get the project tested,” the official said, adding that work was going on at a good pace before the flood.

The reservoir, which will be around two-metre-deep, is being constructed on a 40-acre piece of land. If the pilot project is successful, the government plans to extend it to 1,000 acres next year.

The Irrigation and Flood Control Department was in the process of installing around 12 piezometers to measure the water table before and after percolation in the area.

Increase in water table

“Though the piezometers installed have shown increase in water table compared to what was shown 10 days back, we cannot be sure whether it was due to the flood or water in the reservoir,” the official said.

Now, piezometers will be installed about three km upstream of the project to measure the increase in water table. “We will then compare the readings of both the areas to understand whether the increase is due to the reservoir water or the flood,” the official said.
