Ashiyama water purification plant

The Ashiyama Water Purification Plant is a treatment facility in Mito that processes water through sedimentation, filtration, and disinfection to remove impurities. The central water tower stores the treated water for distribution throughout the city.

The facility opened in April 1932 and operated the region's water supply for over six decades until 1993. It played a key role in developing water infrastructure across Ibaraki Prefecture.

The water tower displays Gothic-style features and decorative reliefs showing crossed fire hose nozzles that represent its role in the city's water supply system. These design choices made the structure a recognizable landmark in Mito.

The water tower is easily visible from the street, though the interior of the facility is not open to visitors. The best views of the architectural details are available during daytime when you can see the Gothic elements and decorative reliefs clearly.

The water tower was designated as a national tangible cultural property in 1996, recognizing both its technical and architectural importance. This designation highlights how significant this structure is to Japan's industrial history.
