Explain your idea further
Adding a couple of water fountains around the university quarter would allow people to refill their water bottles around campus, lead to less waste (As people stop buying bottled water and soft drinks) and healthier students.
How would your idea benefit students?
People would not have to spend money buying drinks within the university quarter, additionally being better hydrated allows people to concentrate better when learning.
How could your idea be implemented?
Literally just by putting a water fountain or two in some of the buildings - if there are any already (which I'm not aware of) they should also be advertised better and clearly marked.
