I have learnt so much and and confidently say this is an instrument and a great tool for individuals and the government to ensuring the health of their communities. Thank you so much for the knowledge from this course.

This course helped me to reinforce the knowledge I have about treatment and safe storage of drinking water. It has excellent material and I recommend it as support for work in the field and with vulnerable societies.

Very informative and practical course as water treatment is very useful and it is very nice to have knowledge about HWTS for a student.Teachers are very knowledgeful and interactive in this course.

It was great course of HWTS. I have a nice project for de-centralized water treatment solution for rural area of low and middle income countries. I need help to implement my project in my region.

Great intro course with renown professional in their respective fields. The interdisciplinary approach makes this course attractive and inspiring especially when you live in developing countries.

very educative course on household water treatment and safe storage technologies........All in all, the suite of courses from Ecole Polytechnique have been most informative.........

Excellent course, i learnt a lot of water treatment, but also about social concern, so i could be quite more aware of social issues happening around the world. Thank you very much.

Thank all the teachers who participated in this course, for me it has been a very important contribution because I am also dedicated to this fascinating field of water treatment.

A very well organised course. Dr. Rick Johnston is an excellent mentor to have! Wish him all the best. Highly recommended for Civil Engineering/ Environmental Study backgrounds.

Thank you so much, for your knowledge sharing. i would like to take up few more courses and get to know more about the things happening everywhere.

It was a great learning on the importance of HWTS . This course has thrown significant knowledge on the potential contaminants of drinking water

Great course!! I had the chance to be aware of many realities and definitely will continue learning with all the papers, books they provide us.

Dr Rick Johnston and his colleague are awesome. They have good understanding of the subject matter. I will recommend this course to my friends.

Gran curso, me encató el enfoqué tecnico ya que soy ingeniero. Aprendí cosas que no conocía y que considero serán muy útiles en el futuro.

This was a great course that cleared up a lot of stuff for me. I would like to thank its wonderful tutor for making this course possible.

This course is very valuable. I learnt a lot in terms of HWTS. Many thanks to EAWAG, EPFL and Coursera teams for this wonderful course.

Excelente curso, super completo y detallado. Explica de forma directa lo requerido para aplicar estos conocimientos en el campo real.

Congratulations for making an excellent course! I'm sure this is going to help me achieving my professional goals. Thank you so much!
