Having understood the working of water treatment plant, the students of classes IX-X got into the task of preparing documentaries in which they not only shared the knowledge received during their visit to MCG Water Treatment Plant, but also added more ideas and implementation strategies to portray waste water stories. The competition was organised on 30.08.2017. These documentaries were shared with the students of God’s Ark School, Nigeria. This competition played a significant role in developing the understanding of right choices to be made for sustainability with local and global issues.
