According to the latest order issued by the department, water-sprinkling anti-smog guns fitted on a truck are under process of hiring, and a budget of Rs 58,834,480 has been approved.
“Budget allocation for providing service of 200 of truck-mounted anti-smog guns on a hire basis for 5 months in two shifts from October 2025 to February 2026, for dust pollution control with environmental messages on the machines,” the PWD’s order states.

An anti-smog gun is a device to combat air pollution which will spray atomised water to settle the dust and other suspended particles in the atmosphere. Equipped with a water tank on a vehicle, it can spray water up to a height of 50 metres to settle dust particles and PM 2.5.
“The machines should be available on hourly basis. Each anti-smog gun should also have 24 stainless steel nozzles to atomize the water,” the tender said further.
