After repeated squabbles with the civic administration over desilting of the Mithi river, the Mumbai Metropolitan Region Development Authority (MMRDA) has now sent an ultimatum to the BMC that it will be doing the desilting work this year for the last time.

Both agencies have been at loggerheads for the past seven years over the desilting of a six-km stretch of the Mithi river, resulting in a delay in desilting and waterlogging in areas around that patch.
