[1]Design and Fabrication of a Coconut Punching Machine placed on a tricycle



NGO/Institution Associated:

Assam Engineering College, Guwahati, Assam


  • To develop an efficient, safe and simple machine for  extracting tender coconut water

Punching and splitting of tender coconut for obtaining its water is normally done with traditional tool like dao whichis unsafe, messy and need skilled hand. The risk of injury to the operator is also high. There are some machines for punching coconut, but until now no household tool exists to punch hole and split it open. This necessitated developing a punch-cum-splitter for tender coconut.

It consists of a punch to pierce a hole in the coconut. The machine has a foot operating pedal which enhances vertical movement of the tool. The operator puts the coconut in the clamps with his hand and applies force paddling with his limb. The two springs provided in the frame allows quick return of the tool which saves time and self positioning of the tool for next operation.
The whole mechanism is placed on a tricycle. This facilitate the vendor to operate coconut punching at ease and also enables to carry and transport bunches of tender coconut for trading

Sono 3-Kolshi water filtration system

Contribution towards strengthening RuTAG:

A simple coconut punching and opening machine for trading tender coconut has been developed

Current Scenario - Multiplication/entrepreneurship etc:

Dissemination of the technology has not yet taken off.







[1] Sono 3-Kolshi water filtration system for removal of arsenic



NGO/Institution Associated:

Rural Volunteers Centre, Silapathar, Assam


  • To demonstrate the use of arsenic free drinking water with Sono 3-Kolshi water filter.

Sri Rabindranath, Chief Executive of Rural Volunteers Center, Dhemaji, a voluntary organization working in the Dhemaji District and adjoining areas of upper Assam and Arunachal Pradesh and parts of Arunachal Pradesh, presented the problem of Arsenic contamination in the ground water of Dhemaji and Karimganj district of Assam. The RuTAG-NE decided to adopt Sono 3-Kolshi water filtration system technology designed by a group of scientists of Bangladesh and West Bengal in the area.

The technology of Sono 3-Kolshi filtration system for removal of arsenic from arsenic contaminated water was demonstrated under the supervision of Rural Volunteers Centre, Silapathar and Dhemaji in five different locations of the district of Dhemaji where ground water is heavily contaminated with arsenic.

Sono 3-Kolshi water filtration system

Contribution towards strengthening RuTAG:

Result shows that the filtrate water is free from Arsenic. The technology is helpful in potential arsenic prone and flood affected areas for obtaining arsenic free drinking water.

Current Scenario - Multiplication/entrepreneurship etc:

The technology has been handed over to Rural Volunteers Centre, Silapathar, Assam, for its further dissemination
