Namami Gange

By | June 20, 2016

This Government is very much enthusiastic related to cleaning Ganga River. In 2014, when new Government got elected they set up different ministry to look after this project. Government is also roping in other countries for dual purpose, one is investments and other purpose is technology. Countries like Germany and Israel have already pledged that they will help India in this project. Germany has promised that it will provide 3 million Euros. There could also be assistance and collaboration in areas like strategies for rejuvenation of Ganga, defining the prime spots, assigning priority to various areas of work, evaluating and monitoring the basins of Ganga, and establishing Ganga knowledge centers. Israel, one of India’s biggest defence partners, wants to offer its expertise in water management and help the government with its ambitious Ganga cleaning project. Armed with these water management techniques, Israeli officials have met their counterparts in the Union Ministry for Water Resources, River Development and Ganga Rejuvenation, headed by Uma Bharti, to offer help in water conservation and the Ganga cleaning programme.

Lately, Government has set a 3-year target to rejuvenate the River Ganges, formulating an integrated plan for the use of new technologies to solve the water pollution crisis. Currently, Government is looking to technology which can be used for this project.

One such technology is to send SMSes automatically to factory when their industrial wastes extend certain limit. This will be basically a M2M technology. For this government is likely to rope in state-run Telecom Consultants of India, which has submitted a proposal to the ministry for the use of transducers to monitor effluent levels in the Ganga in real time.

Basically, transducer is a device that converts one form of energy to another. Types of energy could include chemical, electrical, acoustic, thermal, mechanical, electromagnetic, etc. So transducer converts a signal which could be of any kind of energy and will convert into another signal which could be another kind of energy. There are various kinds of transducers, for e.g., oscillator transducers, resistive transducers, etc. Following are some of the examples on transducers:

  • a loudspeaker driver converts an electric signal to sound
  • another example could be a transducer might detect pressure (a mechanical form of energy) and convert it to electrical signal for display at a remote gauge.

Transducers are widely used in measuring instruments. In Ganga project, these devices will convert chemical parameters into electrical information, process and transmit the data and are capable of sending automated SMSes through mobile networks to alert the authorities.

The challenge over here is the availability of transducers in the country and their cost. About 100,000 units would be needed for the Ganga project and each imported transducer costs close to $30,000. TCIL expects the cost to go down if transducers are manufactured locally, in line with the government’s ‘Make in India’ initiative.
