One of the biggest problems in Mexico City is the floods that tend to be more common in areas with low and medium low levels are grouped in Gustavo A. Madero, Iztacalco, Iztapalapa and Venustiano Carranza. Ironically, most of the colonies identified as having a high risk of flooding by the Water System are located in the north and northeast of the city, where the level of precipitation is low. This may be due, in part, to areas with a lower elevation or insufficient drainage capacity.
In the urban area of the CDMX each year an average of less than 600 million cubic meters of water falls, that is 2.1 times the average volume supplied annually by the Cutzamala System, which represents 27% of the city's supply.

The British company dedicated to construction and which focuses mainly on the development of sustainable materials, Tarmac, has designed a porous asphalt capable of draining all the water you want to throw. Something as important in our day to day as the roads are, they needed a real technological revision. If you have already created asphalt lanes that store solar energy, kinetics or even recharge your electric car while you drive through them, a modern solution was missing for the puddles and the accumulation of water on days of heavy rain. The system The idea is not complicated, drain the water, but it can be its practical application. It basically consists of a multilayer system based on crushed permeable granite instead of the sand concrete that is commonly used. Once installed, the water 'course' can take three different paths: Filter the water completely and directly to the ground, only suitable for accustomed lands that do not suffer with it Accumulate it under the asphalt and reuse it for irrigation or even leave a part stored to cool the surface on hot days, ideal for urban streets, for example Conduct it through a semipermeable layer to the sewer system The application: Here could be a bit of jamming and puddles of the invention, because the cost of the material is greater than that of common concrete and, in addition, it would need a previous preparation of the land, which would trigger the budget. In addition, there is the issue of very low temperatures. In principle, a freezing of underground water, if storage is decided, could lead to cracks in the structure. However, the company states that it carried out tests in extreme conditions and the asphalting did not suffer great variations. Regarding possible interference from filtering, they also pointed out that the level of land and other external agents must be very high for this to happen.
