It is raining in Mumbai. The roads, streets, squares and squares are all submerged in water. The surging Arabian Sea keeps the Marine Drive wet. But when there is waterlogging, Mumbai’s heartline i.e. the local train stops. BEST buses also face difficulty in running. Pictures of vehicles stuck in water are seen at many places. The same is the case with Delhi. The national capital starts suffocating with a little rain.
But why doesn’t this happen in big cities like London? Which wings of Surkhab are there? First let’s know the problems of Delhi and Mumbai. After this, read about the system in cities like London, which does not cause waterlogging and waterlogging.

Delhi and Mumbai’s problem…
Inadequate infrastructure… Both Delhi and Mumbai are struggling with very old and inadequate drainage systems. These systems cannot handle heavy rainfall. Hence, severe flood-like situations arise. Every time it rains, waterlogging and flooding occurs three to four times. Because the sewerage systems are not able to function.
Lack of rainwater harvesting… Some work on rainwater harvesting has started in both Mumbai and Delhi. But it is not on a large scale. Nor has this system been linked with the city’s planning. Whereas in London, this system has been in place since the very beginning. If this is implemented, the city can conserve the right amount of water.
Urbanization and climate change… Due to rapid urbanization, the water-absorbing areas have decreased. Wetlands and green spaces are decreasing. Due to climate change, rains occur more frequently and at times. This puts a lot of pressure on the current drainage system.
Limited government assistance… Like the government of London, there is a lack of government policies in India. The government should plan a massive awareness campaign and incentive plan for rainwater harvesting. So that people who want to do such things get encouraged. Installing this system in buildings will make water management easier in the city.
What goes better with London…
Rain water harvesting… In London, full attention has been paid to rainwater harvesting at most places. This technology has been incorporated in the buildings. Rainwater is stored and reused. Take the Museum of London for example. It has a roof of 850 square meters. Here 25 thousand liters of water is harvested in the rain. That is, it is stored. Which is used for toilet flushing and irrigation.
Sustainable Urban Drainage Syst… Stormwater management technology is well implemented in London. This reduces the load on the sewerage system. With stormwater management, rainwater can be drained out at the right time. Or it can be collected at one place and reused. This way, rainwater does not go unnecessarily into the sewerage system. Rather, it flows into clean water sources without getting mixed with the sewer.
Laws and incentives… The London government promotes rainwater harvesting a lot. Strict rules have been made for it. It has to be implemented in every new building.
