With Chennai receiving 491% more rainfall between November 7 & 12*, the city once again witnessed flooding in at least 78 locations, including 167 streets that faced severe water stagnation**. In lieu of this, Grundfos India, along with its distribution partner, Siddharth Electricals, supported the Chennai Metropolitan Development Authority, Greater Chennai Corporation, Chennai Smart City Ltd. and residential societies across Chennai with its unique and self-contained Mobile Pumping Station and dewatering pumps.
The Mobile Pumping Station and the dewatering pumps from Grundfos India were operated November 10 – 14 and helped dewater approximately 50 lakh litres during this period. This eased the plight of residents across affected areas such as Chennai MMDA Colony, Adyar and Thiruvanmiyur.
George Rajkumar, Country President, Grundfos India, stated: “We can see the growing effects of climate change already through such recurring flood situations in Chennai. There are dewatering solutions we can use to addresses such flooding immediately. We at Grundfos India worked with local authorities to dewater a few locations across the city. While this was a stop-gap solution to cater to the problem at hand, we urge the authorities to look at long-term flood control solutions that are sustainable and efficient.”
For urban cities, the concept of mobile pumping stations serves as an ideal solution for dewatering flood prone areas where flood control infrastructure is not available. High efficiency mobile pumping stations are light weight and portable for use across varied environments such as low-lying catchment areas, drainage pits and waterlogged facilities. Disaster management teams can effectively deploy such mobile pumping solutions that are easy to operate and install.
The Mobile Pumping Station can be continuously used for 10-12 hours, and pumps at the rate of 300m3 of flood/sewage water every hour. The unit contains two dewatering submersible pumps (11 KW), a crane, as well as DG power supply. This solution is also easily transportable using tractors or similar towing vehicles.
