Environmental organisation Awaaz Foundation has called on the Brihanmumbai Municipal Corporation (BMC) to publish air quality monitoring data from construction sites across Mumbai. Its request includes live readings, equipment calibration records, technical failures and details of enforcement measures against sites violating pollution-control requirements.
In a letter dated October 28 to Municipal Commissioner Ashwini Bhide, foundation founder Sumaira Abdulali referred to the civic body’s November 6, 2025 circular, which introduced a standard operating procedure (SOP) for the functioning of air quality monitors at construction locations.
According to the SOP, monitoring devices must transmit real-time readings to the BMC’s Command and Control Centre and remain operational for more than 95% of the time. Any malfunctioning equipment must be repaired within six hours or replaced within 24 hours. The guidelines also require sensors to undergo calibration every two months, while active construction sites must complete co-location checks within six months.
The circular further recognises zero readings as a possible indication of sensor malfunction. It also provides for show-cause notices and suspension of construction activities in cases where sites fail to comply with the prescribed requirements, the foundation noted.
Abdulali has asked the BMC to create a dedicated public portal where residents can access live pollution readings alongside calibration reports and information about equipment breakdowns. The platform should also disclose repair and replacement records, as well as action taken against construction sites found violating the rules.
The foundation has separately renewed its appeal for the deployment of mobile monitoring vans fitted with advanced air pollution measurement equipment. These vehicles, it said, could provide more accurate and location-specific pollution data across Mumbai.
Awaaz Foundation highlighted the importance of such monitoring during Diwali, when firecracker activity can lead to sudden increases in pollution in particular neighbourhoods. Making timely readings available would help residents understand local conditions and take necessary precautions.
