A month and a half after launching the exercise to wash at least 650 km of roads daily to mitigate air pollution, the Brihanmumbai Municipal Corporation (BMC) has not achieved its daily target. The mist cannons, however, have helped it cover 500 km of roads.

Washing roads is one of the BMC’s measures to tackle air pollution. It has issued anti-dust norms for building contractors and served notices to errant ones, it removed furnaces and has considered setting up air filters on vehicles. Of the total 2,050 km of roads in the city, it aimed to wash 650 km daily so that each road is washed at least every three days. Its next target was to wash 1,000 km of roads daily to reduce the interval between every wash to two days.
