Journal No. 3 (13th Week): An Underground Project

Singapore is a country where water resources are scarce. One day a university professor came out with an idea of storing rain water in subterranean cavern. The government thought it was a good idea and formed a task force to study if the professor’s idea was viable. Initial finding shows that a subterranean cavern would eventuate in earth movement or soil collapse unless the cavern formation is of granite material. Further study shows that even if granite formation is available, harmful gases could be emitted by trapped organic substances. Ultimately, the task force concluded that the project is so cost prohibitive that it was not viable.
