Delhi cracks down on construction dust with real-time monitoring as pollution battle intensifies

The Delhi government has intensified its crackdown on construction-related dust pollution, with Environment Minister Manjinder Singh Sirsa announcing that construction sites across the city are now under strict real-time monitoring using cameras, air-quality sensors and automated surveillance systems. The Delhi Pollution Control Committee (DPCC) has inspected 1,262 construction sites larger than 500 square meters since mid-October, issuing over 200 show-cause notices, shutting down 48 non-compliant projects and imposing fines worth ₹2.36 crore. “Sirsa said the government is now using sensors and cameras at construction sites to track the level of dust particles in the air.” through 360-degree CCTV and dust sensors linked online to the DPCC portal, allowing continuous supervision and instant detection of violations.

Studies by TERI and the Automotive Research Association of India (ARAI) have shown that construction dust accounts for nearly 25 percent of PM₁₀ and 17 percent of PM₂.₅ pollution in Delhi during winter months, making it one of the single largest contributors to seasonal smog and poor air quality. To address this, all construction projects over 500 square meters are now required to register on the DPCC’s Dust Pollution Control Self-Assessment Portal, display publicly visible registration boards on site, and upload compliance data including details of dust-control measures, use of anti-smog guns, regular water sprinkling and covered material storage.

Sirsa said that enforcement teams have been strengthened, with 35 inspection squads and more than 1,800 officials now conducting ground checks. The monitoring portal has also been integrated with municipal building approvals, ensuring that no construction project can receive or retain permission without proof of registration and active dust-control compliance. Large sites are being asked to deploy multiple anti-smog guns, suppressors, wind-barriers and debris management systems, while diesel generators at construction locations are being checked for emissions and retrofitting.

The minister emphasized that pollution control in Delhi is moving from symbolic action to data-driven regulation. He warned that sites failing to comply with dust norms will face not only financial penalties but also immediate closure. He also appealed to citizens to report violations through helplines and mobile apps. The government believes that if construction dust which contributes between 10 to 30 percent of particulate pollution depending on the season is effectively controlled, it will substantially improve Delhi’s baseline air quality and reduce the severity of winter smog.

Officials say that sustained enforcement, stricter compliance and transparent monitoring can make a measurable difference, and that technology-led supervision is key to ensuring accountability in pollution-heavy sectors such as construction.
