Delhi has experienced severe air pollution in the months of November and December in the past few years whenever wind speeds reduce. This period also coincides with stubble burning in adjoining states, vehicular pollution, etc, adding to the issue.
To tackle this, the engineering company has put up a wind breaking wall around the entire 3km periphery of the site.
The barrier wall controls air currents and prevents erosion by obstructing the wind near the ground and stops the soil from blowing off-site, a source told TOI.
Furthermore, eight anti-smog guns have been installed at vantage points, which spray fine droplets of water over the site which helps dust particles settle down, and curbs creation of any further dust amid digging and other construction activities.
The project has to be completed by the contractor before January 26, 2022 as the Republic Day parade will take place on Rajpath. The efficacy and adequacy of the pollution-control measures were being monitored by a dedicated team, a senior company official said.
Four water tankers have been provided for periodic sprinkling of water, while care is being taken to limit dust pollution from stone cutting and grinding works. Alongside, there is an automatic wheel washing facility made at the exit gate with more to be installed in the weeks to come.
To maintain air quality, the company is carrying out ambient air monitoring through an NABL-accredited agency.
Pocket monitoring meters are being used for daily checks and reviews are being conducted periodically based on feedback from stakeholders.
