This is an industrial facility of Japanese colonial period showing the technological development level of the time.

It is also a very important research material for engineering works like water supply system. It had been used as a water purifying facility until recently. It is well preserved, so possibility of reusing or recycling is high.

Facilities such as gauging well, sedimentation basin, machine room, filter basin, chlorination room, clear well, and distributing reservoir remain as they were. So, it is worth preserving.
