Calm local town excited on expected World Heritage registration of old pumping station
Residents near the riverside pumping station in
Nakama City, Fukuoka Prefecture, had been little aware of its historical
importance until a few years ago. Cherry trees planted inside and outside of the
compound of the facility provided a nice location for local people to enjoy
cherry blossom viewing parties. The site was also sometimes used as a shelter to
protect people from floods, according to Manabu Hamada, a Nakama City government
official.
The 105-year-old pumping station has come into spotlight this year,
however. The facility was among the 23 industrial assets in eight areas across
Japan recently recommended to be registered as World Heritage by a
UNESCO-affiliated organization.

The Onga River Pumping Station started supplying water to the Imperial Steel Works,
Japan, in the Yahata area of the current Kitakyushu City, in 1910. This was
about 10 years after the inauguration of the steelworks as a symbol of Japan’s industrialization drive in the decades after Japan opened itself to the western
civilization toward the middle of the 19th century.
The pumping station is still in operation, providing
120,000 tons of water a day to the Yahata steelworks. This is 70 percent of
water used there. Water is used to cool the blast furnace body and steel rolled
out of the mill, and to clean steel sheets and other products. Overall, 200
tons to 300 tons of water is said to be necessary to make one ton of steel.

The pumping facility, located in the inside of the east bank of Onga
River, is capable of providing up to 180,000 tons of water to the steelworks,
currently owned by Nippon Steel and Sumitomo Metal Corp.
The pumping station is actually a rectangular, double-ridge building. The walls are covered with red bricks, while gray slag bricks are used for beams and arched window frames. The design provides a stylish outlook to the building as a whole.

The northern section of the building was used as a pump room and the southern section housed a coal-burning boiler which provided power to a steam engine. The facility started operation with four pumps introduced from Hathorn, Davey and Co. of Britain. The boiler and steam engine system was introduced from Babcock and Wilcox, also of Britain. The facility was electrified in 1950, but at that time, the building and related structures were preserved almost as they were.

River water is taken at a point up on a water gate and funneled into a settling pond in the northern area of the facility compound. An 11.4-kilometer water supply pipe starts from the northern end of the compound and crosses a branch of Onga River,
and then it runs northwardly and eastwardly toward the steelworks.

Three historically important structures at the steelworks
in the Yahata area are also among the candidates this time recommended for
World Heritage registration.
The compound of the steelworks is sandwiched by
the sea to the north and an amusement zone and densely populated areas to the south.
The candidate assets there are not open to the public. Visitors
can only have a distant view of one of the three structures from a recently
built viewing deck. No entry or photo is permitted. Instead, visitors can take
a look at monuments set up at part of the site formerly occupied by the
steelworks.

The 10th generation model of the No. 1 blast furnace, which was in operation
from 1962 to 1972, is preserved and opened to the public at a site near the
steelworks compound.
The recommendation by ICOMOS, the UNESCO-affiliated
entity, for the “Sites of Japan’s Meiji Industrial Revolution: Iron and Steel
Making, Coal Mining and Shipbuilding,” has paved the way for the 19th case of
World Heritage registration of natural assets and other globally important sites
in Japan.
The recommendation must be authorized by a UNESCO
committee in charge of the matter at its meeting from late June to July. Indications
are that the recommendation will be adopted at the meeting, but South Korea has
raised objection to the recommendation, claiming that some of the 23 assets are related to forced labor involving Koreans taken from their homeland when Korea was under colonial rule by Japan from 1910.

Hamada is a key person of a five-man task force set up by
Nakama City, southwestern Japan, in April 2014 to promote the pumping station as part of the candidates
for World Heritage registration.
Nakama City, with a population of 43,000, has so far had few tourist assets, It had
no budget for tourism-related activities until last year, but the former
coal mining town has earmarked 30 million yen for tourist-related purposes
this fiscal year, according to Hamada.
No entry is permitted into the pumping station compound,
because it is a working, high-voltage facility. Some other candidate sites recommended
this time are also operating, among them a shipbuilding yard crane. If registered, these facilities will be the first operating World Heritage assets in Japan.

The compound of the riverside facility had been surrounded
with densely planted trees. The facility could be little seen from
outside, but many of the trees were cut down earlier this year, enabling people to
have a look at the facility from outside.
On a holiday in early May, just after the ICOMOS recommendation
was made public, the sites involved were flocked by hundreds to
thousands of visitors. The Onga River Pumping Station attracted at least 450 visitors on
that day, said Hamada. After the initial fever, the number of visitors comes to
around 100 on weekends.
The pumping station was not included in a provisional
list of World Heritage candidates prepared by the Japanese government in 2009. Later
in the year, a group of experts took a firsthand look at the facility and
recommended that it should also be included in the candidate list.
A large water supply system was indispensable for steelworks in the modern times.
This means that a water supply facility was always built as part of a
steelmaking project. “This is what experts (in the steelmaking business) equally
stress,” said Hamada. The pumping station attests to this theory as it
continues to operate at the original site.

When the site will be actually registered as a World
Heritage, “we will have many jobs, not just to better preserve the facility
but also to make it available as an asset for the public, so that its historical value may be disseminated,” Hamada said.

People in the Meiji era carefully used old items and
assets as long as possible. When the power for the pumping station changed to
electricity from steam and then, when the facility was shifted to an unmanned
operation, “they (the facility operators) could have rebuilt it to a smaller, easier-to-maintain facility, by
scrapping old and unnecessary items and sections, but they did not do so,” Hamada said.
“This may be a spirit of craftsmen in
the Meiji Era,” he said. “We can learn their view by looking at this facility and we will have to preserve the asset toward the years ahead.”
