"The DGCA has sought reply on certain things like who will be responsible for the cloud seeding operations, how the civic body will go ahead with it ?..Hence the process may be delayed and the experiment might commence in the second week of September," said R B Bambale, Hydraulic Engineer in BMC.u00a0

The exercise aimed at increasing water-level in catchment areas in the metropolis, following deficient rains, was earlier scheduled from September 1-28. The civic body requires DGCA's permission on the air space to be used by a plane before it goes ahead with the procedure.
