Mumbai Comes To A Hold

Why Mumbai's drainage system fails

Mumbai is India's Financial Capital, and it's most developed city among other cities. And it's rainy season hitting the city ever single year with more and more problems at its starting.
The government has also promised with better management, yet roads are seen water logged every year during the monsoons, bringing the city to a halt and all the fault is put up governments name.

But we have to know what is the real problem:

The real problem is Drainage System which was built in the British Raj.
The old system worked on simple principle, flowing the water away from the source and dumping in to the Arabian Sea. Then the population was not much and the system was capable of doing the work. But one factor was not taken under consideration and that was the High Tide Level.

As the years passed and the population and level of high tide raised with time and the load on the system grew. The System was also made capable of handling the new increased level with help of pumps and new lines. Also at times of monsoon in the city, there is increase in the level of water in the system and the combination  of the three things ...Rain, Population and Old Drainage System makes the city come to hold with many places having water logging and flooding.

 Also the system is not developed to resist the reverse flow of the sea water. The city also takes the help of the Mithi Nadi (Mithi River) but due to silt formation the water holding capacity reduces and creates flooding in city.

The System can be made resist to the reverse flow by the single flow valve. Cleaning of the system and also having proper depth of the drainage system and have pumping station at various places of the city. The System which takes the help of Mithi River should be clean and made silt free for proper discharge. Also the reclamation near the river should be stopped and increase the width of river.

Great Man-Made River (GMR)

Libya's Great Man Made River: The Great Man-Made River in Libya is one of the most ambitious Civil Engineering Project in history of mankind.  In the year 1953, the Libya Government found out not only vast oil reserves but also vast quantity of fresh water locked under the strata, most of the water was trapped around 7000-30000 years ago which is divided in 4 different basins. The first basin is named Kufra basin which is neat Egypt Border which covers almost 35000 sq kilometer which is quite deep around 2000 m deep. The other basin is in Sirte Basin which cover 10000 sq kilometer, third in Murzuk Basin and the last in Jabal Fezzan Basin covering 4800 sq kilometers area.  The GMR project will be used to transfer water to North of the country to provide water for irrigation purpose for more than 6 million  people. This will be a changing point  for Libya and the Colonel Muammar Gaddafi called it the Eighth Wonder of World. The work started in 1984 of the project and estimated to be
