Gear up for monsoon floods with advanced storm water management technology [June 2012]
After beating the summer heat, comes the cool and drenching monsoon. This change in the weather brings us delight and pleasure. On the other hand many find this season inconvenient as it affects millions of people. During monsoon, most of the places are flooded with water and people are unable to walk in the knee high water filled on the roads. It is estimated that, more than 5 million people have hit by floods caused by annual monsoon rains, forcing many to flee as rivers burst their banks.
The effects of Floods are different in rural and urban settings. In urban setting, there is a huge economic loss, flooding leads to damages of roads, collapse of bridges, traffic congestion, which may affect the daily operation. People loose life and infectious diseases are spread. The main reason behind the problem is mainly due to lack of well planned and inadequate capacity of storm water drainage system. To limit the potential damage of coastal and inland, flooding requires a pump solution that is dependable and effective. In the longer term, flood control solutions should prevent damage of infrastructure and the potential risk of famine.
The innovative technologies used for storm water management gives cut edge result and lasts long. The pumps are installed in tubes, which are capable of handling extreme situations. With local presence, fast delivery, superior service support and state-of-the-art solution, the complete mechanical, electrical and automation systems are supplied to ensure perfect system compliance and reliability. The whole system will be controlled by SCADA, which tracks back the remote sites equipped with sensors.
Due to high tides during monsoon, the tides prevents the flood water from entering the sea and the water flows back to the city resulting in increase of water level and submerged of low lying areas. The flood water enters the pumping stations and submerged the pumps too. To avoid these circumstances, the pumping station is set up on the edge of an upstream of tidal control. The water collected in the inlet structures flows through a covered underground channel to the pump house. During the floods, when low tides conditions persist, the tidal control gauge remains open and the flood water passes through the gauge and flows into sea. But during high tide conditions, the gauge will be closed. The storm water from the city is diverted into the intake structure and to the pumping station. This water will be pumped into the channel and the water will be discharged into the sea.
Grundfos India has pioneered in providing storm water management technology, which helps to gear up for the monsoon floods confidently. The company offers the pumps and control solutions to meet the increasing demand. Grundfos India has designed reliable flood control solutions that will be immense help for managing storm water.
Grundfos India sets up a complete electro-mechanical solution, consisting of 4 numbers of 300kW heavy duty wastewater pumps delivering 4000m/hr, at 20m head with 6000v. Southern Avenue, Kolkata takes the credit of having the first storm water pumping station in India, which features complete automation with provision of SCADA systems too. Also, Grundfos India has provided the comprehensive solutions to flood control problems in Watgunj, Tala and Palmer Bazaar in Kolkata.
Also, the Mumbai Municipality has set up a pumping station in IRLA, central Mumbai, with the help of Grundfos India to deal with storm water. Grundfos provided a complete comprehensive solution, which consists of 8 numbers of 500kW axial flow pumps, delivering 6m3/second, at 6m head, along with soft starters, LT panels, HD panels and SCADA systems to sustain in the extreme conditions. Considering the tough conditions during monsoon, these pumps are designed to operate with decent and unique generating sets, which are helping Mumbai Municipality to manage the flood situation successfully.
