PMC Makes Sensor-Based Air Quality Monitoring Mandatory at Construction Sites to Tackle Pollution

Pune Municipal Corporation mandates real-time sensor-based air quality monitoring at construction sites to curb dust pollution and protect public health.

Pune | 26 February 2026: In a major step toward tackling rising air pollution levels, the Pune Municipal Corporation (PMC) has made it mandatory for construction sites across the city to install sensor-based air quality monitoring systems. The move is aimed at reducing dust emissions generated from construction activities, one of the key contributors to deteriorating urban air quality in Pune.

Under the new directive, ongoing and upcoming construction projects will be required to deploy real-time monitoring devices capable of measuring particulate matter levels, specifically PM2.5 and PM10. These fine particles, often released during excavation, demolition, and material handling, are known to pose serious health risks, including respiratory illnesses, asthma, and cardiovascular complications. By installing sensor-based systems, the civic body intends to monitor pollution levels continuously and enforce timely corrective measures.

Civic officials stated that the regulation applies particularly to large construction sites exceeding specified built-up area thresholds. Developers must install approved air quality sensors along with LED display boards that publicly show real-time air quality readings. The displays will use color-coded indicators to inform workers, inspectors, and nearby residents about pollution levels at the site. If dust levels exceed permissible limits, immediate steps such as water spraying, covering debris, or halting certain activities may be required.

The policy is aligned with environmental compliance norms under national pollution control regulations and broader clean-air initiatives being implemented across Maharashtra. Rapid urbanisation and infrastructure growth have significantly increased the number of construction projects in Pune over the past decade. As a result, dust from construction sites has become a major source of airborne particulate matter, especially during dry seasons.

To ensure technical accuracy and reliability, PMC has coordinated with scientific and environmental experts to standardise sensor specifications. The collected data will be integrated into a centralised monitoring system within the civic body’s environment department, allowing officials to track pollution trends across multiple sites simultaneously. This technology-driven approach is expected to improve transparency and strengthen enforcement mechanisms.

Failure to comply with the new mandate could result in penalties, including show-cause notices or temporary work stoppage orders. Authorities have clarified that the objective is not merely punitive but preventive. The goal is to create accountability within the construction sector and encourage developers to adopt sustainable building practices.

Environmental activists have welcomed the move, calling it a long-overdue step in addressing construction-related pollution. However, they have also emphasized the need for consistent enforcement to ensure that the policy is not limited to paper directives. Regular inspections, calibration of sensors, and strict action against violators will be crucial to achieving measurable improvements in air quality.

Builders’ associations have indicated their willingness to cooperate, acknowledging that environmental compliance is increasingly becoming a core component of responsible urban development. Many developers have already begun installing dust suppression systems such as mist cannons, barricading, and net coverings to minimize emissions. The addition of real-time monitoring technology further strengthens these efforts.

Urban planners point out that technology-backed environmental monitoring can significantly enhance governance. Real-time data enables quicker response times, reduces manual inspection burdens, and builds public awareness. Residents living near construction zones will now have better visibility into air quality conditions in their surroundings.

As Pune continues to expand with new residential, commercial, and infrastructure projects, balancing development with environmental sustainability remains a pressing challenge. The PMC’s decision to mandate sensor-based air quality monitoring represents a forward-looking step toward cleaner urban growth.
