Our results can be achieved because of the numerous resources available on the internet. With a snap of the finger, we were able to find knowledge. Research means the systematic investigation into and study of materials and sources in order to establish facts and reach new conclusions. After collecting data on each tap and the factors that affect them, we will put them in a neat table. This way, we can analyse each tap in a systematic manner. Upon completing this, we will them classify them into another table. Here,we will put ticks to indicate which tap is affected positively or not affected by which factor. This will allow to identify the most sustainable tap by collating the number of ticks it has.
