Build more storm waterways, say experts

Gurgaon: Authority in Delhi-NCR needs to build more storm waterways to overcome urban floods, professors attached to several main institutions in the region have told TII.
Experts show that in most cities, the drainage system is not designed or added to deal with short bursts of heavy rain or unexpected rainy season, both have become quite often over the past few years.
Therefore, they suggest, the authorities must change the size of stormwater disease.
“Yes, the number of rainy days has been reduced due to climate change.
Most of our cities do not have the right drainage pattern.
Strangely, the flow of traffic is considered when planning a road, but the drainage pattern is not.
The sewer network is now not designed to accommodate the rain of high intensity It has been witnessed by the region for the past few years.
As a result, urban floods are more often, “said CR Babu, Professor of Emeritus and Head of the Environmental Management Center for the degradation Ecosystem (Cemde) at Delhi University.
“The waterways we have are designed for drizzle, not heavy rain.
Also, most of the roads don’t have a tree cover.
Trees help rain water to seep into the ground,” he added.
Experts suggest that storm waterways must be separated from those who carry waste.
“The capacity of storm waterways has been reduced by connecting them with waste sewers.
Natural disposal lines have never been considered when planning cities.
Also, storm waterways are filled with solid waste and plastic, which also leads to urban floods.
We It has also lost a number of water bodies, “said Manoj Misra, Convenient Yamuna Jiye Abhiyan, a NGO.
Two scientists from Bengaluru who were in the panel who prepared the IPCC report on climate change this year had notified the previous toi that Delhi-NCR needed to build more water bodies to eliminate increased temperatures.
Scientists – Govindasamy Bala and NH Ravindranath – also say that extreme weather conditions in the form of heat waves and high intensity rainfall will become more often in NCR.
But it is not just the lack of storm waterways that have triggered concern, rapid urbanization, loss of wetlands, large-scale carbon dioxide emissions and changes in urban landscapes are several reasons that contribute to the increase in temperature, according to experts.
“There are several factors that contribute to increased temperatures, such as reducing green cover, intensive concretization, heat waste from air conditioning and heated carbon dioxide emissions.
We need to reduce our carbon emissions,” said Anumita Roychowdhury, air pollution head and transportation program Clean in the center of science and the environment.
Amita Singh, a former professor in JNU, said, “Climate change is a reality.
We need more water reservoirs and administrations to do regular maintenance of storm waterways.”
