Mumbai, known as the financial capital of the country, was flooded once again on Monday. Over 300 mm of rain fell in six hours, leaving Mumbai drenched. 10 percent of Mumbai’s annual rainfall fell between Sunday night and 7 am on Monday, as Mumbai, like cities across the country and the world, is suffering from climate change. Similarly, there are other reasons for this.

On 26 July 2005, Mumbai received 900 mm of rain in 24 hours. This rain that fell in a single day was the rain of the entire month of July. Mumbai came to a standstill due to this rain. 1,094 people died in this rain. Also there was a loss of 500 crores. Even after that nothing has changed in Mumbai. Mumbai comes to a standstill when it rains heavily.

This is the reason for drowning in Mumbai floods?

  1. The city of Mumbai is located adjacent to the Arabian Sea. The city has four rivers, Mithi, Dahisar, Oshivara and Poysar. Mithi river surrounds the entire city of Mumbai. At many places the width of the river is only 10 meters. Hence, the river swells when it rains heavily.
  2. The shape of Mumbai is different from other cities in the country. This city of seven islands off the coast is very low-key in places. In some places even more. In such a situation, the water starts moving towards the lower part as soon as heavy rain starts. Because of this, Sion, Andheri subway, Milan subway and the lower part of Khar have been flooded.
  3. The city’s sewage system is such that the water drains into the sea, but during heavy rains the floodgates are closed due to rising sea levels. These gates are closed to prevent sea water from flowing back into the city. In such a situation, there is no place to drain the rain water. After the water is depleted, it takes 6 hours for the system to recover.
  4. In most cities in the country, rainwater gets absorbed into the ground, but the situation is different in Mumbai. 90 percent of Mumbai’s water flows away. This also puts a heavy burden on drainage.
  5. People come to Mumbai from all corners of the country. There is no plan to accommodate so many people. Many people live in low-lying areas. It has been encroached upon. Because of this, water accumulates in many low-lying areas even during low rainfall.

These projects are under discussion

For some time now, there has been a discussion about building an underground pipeline (underground discharge channel) in Mumbai with the help of Japan. Japan also built this project in the city of Tokyo, as more than 3.5 million people in Tokyo are always at risk of flooding. Due to which Japan has created an underground channel. This allows flood water or excess water to pass through this channel and is released into the Edo River by pumps.

There is also talk of developing Mumbai like a sponge city. A sponge city is a concept in which a city acts like a sponge. That is, as soon as water is added to it, it dries up. Under this, the city will be designed in such a way that the water will go directly into the ground and there will be no load on the drains. Green space will be increased in this.
