Thane’s Infrastructure Dust Crisis: When Development Costs Clean Air
Government infrastructure projects across Thane district create severe dust pollution, raising questions about enforcement of pollution control norms at MMRDA and MSRDC construction sites
For commuters in Thane district, air pollution is not just a number on a smartphone app. It is the grit between their teeth during the daily commute, the persistent cough in children, and the layer of grime that settles on windowsills each evening. Along critical infrastructure corridors like the Ghodbunder Road and the Mumbai-Nashik Highway, dust from construction sites operated by state agencies has become a daily reality.
The Maharashtra State Road Development Corporation (MSRDC) is conducting road-widening work from Majiwada to Wadpe on the Mumbai-Nashik Highway. The Mumbai Metropolitan Region Development Authority (MMRDA) has Metro Line 4 construction underway from Wadala through Ghatkopar to Kasarvadavali. Both projects involve extensive excavation, debris piles left roadside, and frequent movement of heavy vehicles. Yet visible dust-control measures remain largely absent.
Thane has experienced elevated air quality readings in recent months. The Maharashtra Pollution Control Board (MPCB) has identified ongoing infrastructure work, heavy vehicle emissions, and waste burning as primary contributors. While Mumbai’s civic body has issued hundreds of stop-work notices for violations at construction sites, enforcement at government infrastructure projects in Thane appears reactive rather than proactive.
Where Thane’s Dust Problem Lives
Major infrastructure corridors showing visible absence of mandatory pollution control measures
Metro pillars erected, roads excavated and re-laid. Debris piles remain roadside without covering. Heavy dust reported by two-wheeler riders.
Majiwada to Wadpe stretch under widening. Work active in Bay Bridge area. Motorists report dust exposure during peak hours.
New connector road project begun. Excavation active. Local residents complain of dust settling in homes near construction zone.
According to ground observations and local reports, dust-control measures such as water sprinkling, green cloth covering, and perimeter fencing mandated by MPCB guidelines issued October 17, 2025 are not visibly implemented at these major government infrastructure sites.
The rules were announced about two years ago by the Maharashtra Pollution Control Board. These include sprinkling water to prevent dust in construction, building a 25-foot-high iron fence with green cloth trap for sites exceeding an acre, covering construction areas, and ensuring soil transport vehicles are covered. These regulations apply to private projects. Citizens have questioned whether they also apply to government projects.
MSRDC Superintendent Engineer Ramesh Pocket stated: “Relevant contractors will soon be instructed to take measures regarding pollution control at work on the Mumbai Nashik Highway.” The Mumbai Metropolitan Region Development Authority could not respond even after receiving requests for comment.
Former Deputy Mayor Naresh Mhatre said a letter has been given to the Thane Municipal Commissioner regarding the large-scale dusty conditions spread over the Ghodbunder area. “If no action has been taken, we will agitate,” Mhatre stated.
The Rulebook vs. Reality
MPCB guidelines for construction sites—compliance status at Thane’s major infrastructure projects
The Central Pollution Control Board mandates dust-mitigation measures under the National Clean Air Programme. The MPCB’s guidelines apply to all projects exceeding 20,000 sq.m. built-up area or requiring environmental clearance—including government projects. Yet MSRDC’s statement that contractors “will soon be instructed” on pollution control indicates reactive rather than proactive enforcement.
Meanwhile, across the Mumbai Metropolitan Region, authorities have taken various actions to address air pollution. The Maharashtra Pollution Control Board shut down Ready Mix Concrete (RMC) plants following compliance surveys. In Mumbai, the Brihanmumbai Municipal Corporation (BMC) has washed 676 roads covering 1,888 km, which amounts to around 92 percent of Mumbai’s total road length. The corporation also removed 665 metric tonnes of garbage from public spaces, along with 18 MT of construction debris.
The BMC’s environment department is planning to increase the penalty against open burning from ₹500 to ₹5,000, similar to Navi Mumbai and Thane municipal corporations. Open burning is one of the major causes of air pollution in Mumbai, especially in areas with slum settlements.
Mumbai is preparing to launch its first dedicated air-quality monitoring platform, the Mumbai Air Network for Advanced Sciences (MANAS). Developed jointly by the BMC and IIT Kanpur, the platform will include 75 low-cost sensors, each covering 0.5 sq km. MANAS will integrate an AI-based predictive model, the first of its kind in the country. The system is expected to go live within six months.

Actions by different agencies to address construction dust and air pollution
The situation in Thane district involves observable dust pollution from large-scale infrastructure projects operated by MMRDA and MSRDC. Maharashtra Pollution Control Board guidelines for dust mitigation exist for construction activities exceeding 20,000 sq.m. or requiring environmental clearance. Representatives of implementing agencies have acknowledged the need for contractor instruction on pollution control measures.
Health concerns identify construction dust as a contributor to respiratory issues, eye irritation, and dermatological complaints. Between January and November 2025, Thane Municipal Corporation found 73 of 377 inspected construction sites violating dust norms. Local representatives have communicated public grievances to civic authorities regarding the dust issue.
The Mumbai civic body has issued stop-work notices to construction sites for violations. Mumbai is developing MANAS, a hyperlocal air quality monitoring system with 75 sensors covering 0.5 sq km each, featuring AI-based prediction capabilities, in partnership with IIT Kanpur. The system is expected to launch within six months.
Across Thane’s infrastructure corridors, two-wheeler riders navigating dust-laden routes experience daily exposure. The enforcement of pollution control rules at state government infrastructure projects remains a question raised by citizens and local representatives.
