The university has installed water servers to promote equal access to safe water and encourage the elimination of plastic on campus. The number of users has continued to grow due to more health awareness and increased consideration for the environmental, to the point that there are long lines at the servers during class breaks. 

A usage analysis found that the servers supply water 3,000 to 4,000 times a day. To alleviate congestion and promote further use, five more water supply stations were added, for a total of 10 water serving stations on the Yotsuya Campus.
