New Delhi: In a significant effort to tackle urban air pollution, the Municipal Corporation of Delhi (MCD) has reported substantial success under its Dust Free Delhi Initiative in Karol Bagh Zone, where a 41-day intensive road dust mitigation campaign led to the removal of 228 tonnes of roadside dust and 150 tonnes of garbage and debris from major road corridors.
The initiative was launched to address road dust, a major contributor to particulate pollution, particularly PM10 and PM2.5 levels, in the national capital. Delhi’s rapidly growing urban landscape, heavy vehicular movement, ongoing construction activities, deteriorated road shoulders and legacy waste deposits have been identified as key factors contributing to dust accumulation and resuspension.
Unlike conventional road-cleaning exercises, the Dust Free Delhi Initiative adopted a comprehensive and engineering-based approach to dust management. The campaign combined mechanised road sweeping, manual kerb-edge cleaning, water sprinkling, pressure washing, central verge and greenbelt maintenance, construction and demolition waste removal and legacy waste management.
Municipal officials implemented a structured Standard Operating Procedure (SOP), risk-based road prioritisation, dedicated sanitation teams, regular field inspections and continuous monitoring to maintain dust-free conditions across selected road stretches.
The campaign covered approximately 122 kilometres of major Public Works Department (PWD) roads in Karol Bagh Zone, primarily arterial roads wider than 60 feet. Roads were selected based on traffic density, commercial importance and levels of visible dust accumulation.
Dedicated teams comprising junior engineers, sanitary inspectors, sanitation superintendents, sanitation workers, sanitation guards and mechanised sweeper operators were deployed under close supervision to execute the programme.
Officials followed a structured seven-step methodology during implementation. The process included identification of priority corridors, mechanised sweeping of carriageways, manual cleaning of kerbs and verge areas, collection and disposal of waste, water sprinkling and pressure washing, on-site inspections and periodic repetition of the cleaning cycle every eight days.
Special attention was paid to areas typically missed during routine cleaning operations, including road shoulders, footpaths, bell-mouth intersections, central medians and greenbelts.
The initiative also targeted construction and demolition waste, unauthorised dumping sites and legacy waste deposits, which often act as recurring sources of dust pollution.
According to campaign data, the municipality scientifically cleaned 122 kilometres of road network during the 41-day drive. In addition to removing 228 tonnes of road dust, workers cleared around 150 tonnes of debris and garbage from central verges and roadside areas.
Water sprinkling and pressure washing were carried out throughout the campaign, while mechanised sweeper machines operated regularly on both carriageways. Daily inspections were conducted to ensure compliance with prescribed “No Dust” standards.
Officials said the results highlight the scale of intervention required to shift from basic sanitation to a sustained dust-management strategy.
Following the completion of the first phase, MCD has expanded the initiative to cover connecting roads across Karol Bagh Zone. The second phase aims to create continuity between major arterial roads and adjoining road networks, ensuring long-term dust control and improved road hygiene.
Municipal authorities believe the Karol Bagh experience offers a practical framework that can be replicated in other urban areas. The model integrates mechanisation, sanitation manpower, waste management, field monitoring and periodic maintenance into a single operational system.
Officials maintain that road dust remains one of the most controllable local sources of particulate pollution and that sustained municipal intervention, supported by technology-driven monitoring, GIS-based road mapping and regular performance reviews, can play an important role in improving urban air quality.
The Dust Free Delhi Initiative demonstrates that continuous, science-based municipal management rather than one-time cleanliness drives can deliver meaningful improvements in road conditions, dust control and environmental health in densely populated cities.
