Since it was established on November 27th, 1924, the Kumamoto City municipal waterworks
entire water supply has come from groundwater. Kumamoto is the only city with a population
greater than 500,000 people that supplies water to the entire city using groundwater alone.
At the same time, our sewage system plays a key role in ensuring good water quality in thesurrounding area, as well as in promoting eﬃcient use and reuse of energy and valuable water
resources to contribute to a more recycling-oriented society. The Water Science Museum wasestablished as a place where visitors can experience and learn about the sewage system that
protects our water environment and Kumamoto s groundwater, which supplies the entirety of
our water supply and is shared by everyone in Kumamoto.

In October 2000, the Wakuwaku Water Experiment Room was created to commemorate themuseum s 10th anniversary and provide morehands-on learning experiences.
The ingenious HP-shell roof structure utilizes
the facility s gray-water system to ﬁlter andsterilize the rainwater that falls on it so thewater can be reused in the pond and restroom.
All of our exhibits were redesigned in March
2012.
