Suggestion to BMC to launched a project called ‘Pervious Concrete Road Pavement’ on pilot-basis in Mumbai
Pervious concrete an innovative, modified form of cement concrete is a cheap and environment-friendly material that can be used for the construction of several types of structures.
Pervious concrete could be this country’s answer to many effects of global warming, including the urban heat island (UHI) phenomenon.
Biggest advantage of using pervious concrete was its heat absorption capacity.
The absorption of heat is a very important advantage. Due to this, the light is not reflected into the atmosphere. This means the ambient temperature can be reduced by nearly 10-15 degrees celsius. Also, the surface of pervious concrete slabs are cool to touch. One can walk barefoot on them, something that is impossible on conventional concrete slabs.
BMC must use topmix permeable concrete technology to reduce flooding.
BMC which has started concretisation of several major roads. However, it has its adverse effects as rain water does not get absorbed by these roads. Due to this, water-logging takes place, throwing city life out of gear.
It is necessary to use topmix permeable concrete technology for the development of roads in Mumbai. This will ensure that water is drained off from these roads and there will be no potholes. It will also help in increasing the underground water level.
Using pervious concrete will also help recharge ground water and reduce the burden on the existing stormwater drains. It can also minimise the impact of urban heat islands, as the material absorbs sun’s radiation.
In the coming days, we need to adopt steps that are environment friendly and better measures towards water conservation. Adopting the concept of porous concrete is one such step towards water conservation.
Mumbai, which has a saucer-like topography, witnesses severe water-logging during monsoon. Of late, even a small downpour triggers flooding in several areas.
Pervious concrete allows rainwater to permeate, reducing flooding and helping groundwater recharge.
