As part of the various measures adopted to combat pollution at its construction sites, the Delhi Metro Rail Corporation (DMRC) has pressed into service 14 ‘Anti Smog Guns’ (ASGs) at its sites, which throws fine mist from time to time to check the possibility of dust pollution emanating from the construction work.
Currently, as part of its phase 4 corridors as well as some other construction projects, 12 civil contracts are operational across the national capital, a senior DMRC official said, adding that these state-of-the-art ASGs are capable of spraying fine mist up to 70 to 100 metres.
“It is ensured that the water used for sprinkling is free from coliforms, viruses and bacteria. High quality nozzles with droplet sizes of 10 to 50 micro metres are used for greater impact.
