The Delhi Public Works Department is preparing to deploy 28 truck-mounted anti-smog guns across dust pollution hotspots in south and south-east Delhi, with the proposed three-phase arrangement estimated to cost Rs 50.63 crore between September 2026 and June 2029.
The process has been initiated by three PWD road divisions for services intended to control road dust on stretches including R K Puram, Okhla, Nehru Nagar, Sri Aurobindo Marg, Jawaharlal Nehru Stadium, Mathura Road and Lodhi Road. Okhla is identified by authorities as an official pollution hotspot.
Under the proposed allocation, South Road Division-1 and South Road Division-2 will each receive services from eight truck-mounted anti-smog guns. South-East Road Division-2 will receive 12, according to officials cited in the report. Each vehicle will be required to operate an eight-hour shift and complete at least two rounds.
The vehicles will have to carry GPS equipment as well as cameras fitted at the front and rear. The monitoring systems are intended to track operations and record conditions during dust-control rounds. The report does not state that the vehicles have already been procured or deployed; it says the PWD is preparing to obtain their services and that the process has begun.
The plan covers roads where traffic, damaged surfaces, accumulated soil along road edges and the effectiveness of routine cleaning have been identified as important factors. In the Sarai Kale Khan area, officials have pointed to poor road conditions on the route from the Sarai Kale Khan flyover towards Kalindi Colony and Maharani Bagh. The route carries heavy traffic, making road-surface maintenance and regular cleaning operational concerns.
The proposed deployment follows recent action by the Commission for Air Quality Management, which inspected about 35 kilometres of the Inner and Outer Ring Roads across 25 road sections. Four teams examined visible dust and the effectiveness of cleaning on roads under the PWD’s jurisdiction. The inspection found 17 deficiencies linked to dust and construction debris, according to the report.
The PWD’s proposal combines mobile dust-suppression equipment with road repairs and cleaning in identified hotspots. Its implementation is planned in three phases beginning in September 2026 and continuing until June 2029. The next steps will depend on the service-procurement process being undertaken by the three road divisions.
