CHENNAI: A s water crisis is looming large threatening to hit the supply, three student groups have developed innovative technologies that will reduce water consumption at all levels - from household to a restaurant to an industry.

A compact eco-friendly hand wash system ‘Jal Seemak’ was developed by KCG College of Engineering that combines the regular hand wash and finger bowl into recyclable tissue dispenser that delivers a warm antiseptic tissue with soothing fragrance.


Generally, people tend to use more water than what is needed during hand wash. On an average a person uses 500 ml to wash hands although 200 ml is enough. People use finger bowl, wash hands again and use dry tissue to clean-up. In the process, large quantities of water goes wastg. So, the Jal Seemak is designed in such a way that all the needs are met at once. It has a main water tank, heater, organic fill and bio-degradable tissue roll, which passes through the dip tank when a customer press the buttom for tissue.

It took six months for Maruthosh M, Lalith Shenoy S, Vishnu Priya G and Sreevatsan V, all  mechanical engineering students, to realise the product which is a first of its kind and patented. Few hotels in the city are already switching over to the new system to reduce water consumption, the students said.


A group from MAM College of Engineering and Technology in Tiruchy has developed an automatic water flow governor mechanism in rice wet grinder to conserve electrical energy and water. P Prabhu, Vilfrad Kistofer, Anandan and Mohamad Shanawaz, the develeopers, said this technology is useful in every household to cut the electricity bill and water consumption.

A normal wet grinder requires water to be poured manually. If water is not sufficient due to over load, current consumption becomes high and this leads to heating of the motor coils and it causes damage to motor and reduces its life. Time taken for grinding process is higher.

To avoid this problem we have used governor mechanism to enable water flow automatically when needed and conserve energy and prevent loss, the students said. The mechanism can be adopted in a big industry involving the same process as well.
