A senior civic officer told DNA that it is only the proper execution of Brihanmumbai storm water disposal project Brimstowad in last 30 years that rain water in lowest areas like Hindmata drained quickly. However, citizens question that even though rain water in the flooded areas receded comparatively early this year, will the city ever get rid of water logging problems completely?

Mumbai is lined on the west by Arabian Sea and is intercepted by number of creeks. The tidal variation is a major consideration in the system of Storm Water Drains SWD for releasing rain water as well as wastewater into sea. The present SWD system in the city is more than years old and is about km long.
This network consists of underground drains, laterals roadside open drains, minor and major nallas built on the basis of population and weather conditions at that time. The old SWD system is capable of handling rain intensity of 25 mm per hour at low tide. If the rain intensity is more than 25 mm per hour and high tide occurs, there is always a possibility of water logging.
There are 29 outfalls in Western Suburbs draining directly into sea while 14 drain into Mithi River, which ultimately joins Mahim Creek.

Brimstowad project gave relief from waterlogging: BMC
The Brihanmumbai Stormwater Disposal System is a project planned to overhaul Mumbai 's water drainage system. The estimated budget for implementing the project is Rs. Such a high-budget project would require funds from the Central Government. The drain system works with the aid of gravity, with no pumping stations to speed up the drainage. Most of the storm water drains are also choked due to the dumping of garbage by citizens. Reclamation of ponds and obstructions in drains due to cables and gas pipe exacerbate the problem.
