Making cities resilient campaign

One of the current projects ongoing in the city of Mumbai initiated by United Nations International Strategy for Disaster Reduction (UN-ISDR) is the Making Cities Resilient : My city is getting ready campaign.Launched in 2010, it addresses issues of the local governance and urban risk. It entered its second phase 2012-2015; based on the success and stock taking by partners and participating cities in the first phase (2010-2011), the campaign will continue and shift its focus to implementation support, city-to-city learning and co-operation, local action planning and monitoring of progress in cities.MCGM- Municipal Corporation Of Greater Mumbai ( BMC ) works with the support of UNISDR

2. Augmenting Storm Water Drainage System

SWD designed for rainfall of 50mm/hr. System being cleaned to the bottom-most level since 2006.Rehabilitation of old drains, particularly in the Island City.Installation of 9 storm water pumping stations in progress. 2 Pumping Stations already commissioned.Portable dewatering pumps installed at flooding spots.


35 automatic weather stations installed for real time rain fall intensity

The data is monitored, analyzed and the warnings are issued of flooding

Flow Gauges installed upstream of Mithi River to monitor water flow and issue warning to population living down stream.
