Chennai, India deploys tech to manage floods

The Chennai Municipal Corporation is deploying technologies to prevent flooding and water stagnation after cyclone Nivar hit the region last week.

It is using a three-wheeled automated tree-cutter machine in several parts of the city. Also, robotic machines fitted to mini-tractors to lift garbage, an aquatic weed harvester to remove weeds from water bodies, and amphibians used to remove silt from the canals, a news report noted.

According to Chief Minister Edappadi K Palaniswami’s tweets, “High tech machines are being used to remove water stagnation at the flood-prone localities along the water channels such as Velachery, Adyar, and Mambalam.”

Corporation officials said that these machines were used throughout the night to make way for the smooth flow of water. “We have deployed amphibians and robotics machines to remove silt in water bodies in almost all the zones. These machines were all working throughout the night with two officials present,” a government official said.

The robotic tractor was used at the Mambalam canal, while the Adyar Creek was being dredged using an amphibian. The civic body is deploying ‘super recyclers’, which are fitted into huge tankers.

“They also have very broad pipes and more powerful motors, unlike the normal sewage removal machines used in the city. Up to 12,000 litres of water can be sucked out in about 20 minutes with these machines,” the official said, adding that in most of the broad roads, they use this machine and less manual work was involved.

The corporation has distributed six motorised tree-cutters in the city. “Three have been given to the central zone, two to the north zone and one to the south zone,” the official said. The machines were used in several areas such as Adyar, Nungambakkam and Ashok Nagar where several trees fell.

The cyclone has left Chennai with an excess of 36% rain for the season so far. The India Meteorological Department (IMD) has forecast that a low-pressure area may form this week. Weather trackers said there are chances of it intensifying into a cyclonic storm.

The forecasting, planning, and management of critical events help authorities prevent disruption of life and damage to property. Governments rely on several, specific systems for critical event management. Such programmes are essential to national well-being, especially with the increase in natural disasters. But, more often than not, they operate in isolation of each other. According to world experts in Critical Event Management – Everbridge, this approach can create duplication in information and processes, data contradictions, and, when unchecked, could lead to loss of life and damages.

Unlike fragmented or homegrown tools, Everbridge offers the most proven modern public warning platform which delivers best of breed capabilities to help governments and public authorities keep people safe before, during, and after critical events, anytime and anywhere in the world. The Everbridge Public Warning platform delivers the most comprehensive, flexible, and modular solutions for population alerting to suit the needs of each city, state, or country.

The Everbridge front-end alerting gateway can be deployed as a standalone solution through to more sophisticated hybrid or multi-channel systems. This combines cell broadcasts or location-based SMS technology to send targeted alerts to mobile phone users, through secondary channels including mobile apps, emails, SMS, voice calls, sirens, radio, television, social media, and opt-in address-based systems.
