Busan: high-performance water

Annual Report 2022 Megatrends Water supply Water

Urbanisation has been a global megatrend for some time now. More and more people are moving to urban areas. Cities already account for ten percent of global water consumption. People are living and working in increasingly tall buildings – a development that poses considerable challenges for the water supply. The volume of water transported to major cities and pumped to great heights is increasing as a result of urbanisation.

Haeundae Doosan We've the Zenith Gebäude

Haeundae Doosan We’ve the Zenith is a perfect example of this challenge. The trio of skyscrapers is one of Korea’s tallest residential complexes. The towers make a striking impression on the skyline of the South Korean metropolis of Busan. Wilo pumps and systems ensure the supply of heating water, drinking water and water for fire-fighting – all the way to the top floor. The facts and figures are impressive: Reaching a height of 301 metres, Tower A, the tallest of the three buildings, is just 30 metres shorter than the Eiffel Tower in Paris. It offers housing across 80 floors in the best location in Busan. Altogether, the three towers contain around 1,800 apartments. Wilo pumps and systems are used to ensure the reliable supply of heat and water.

Highly efficient water supply

134 Wilo Cronoline IL pumps transport heating water through the veins of the skyscraper, while 15 Wilo PUZeN MVI pressure boosting systems and twelve Wilo Multivert MVI high-pressure centrifugal pumps are in place to supply drinking water. Additionally, 19 Wilo PMT and Wilo PMV fire-extinguishing systems have been installed to supply water to the building in the event of a fire.

Haeundae Doosan We've the Zenith Gebäude

Metropolis by the sea. With 3.5 million inhabitants, Busan is the second largest city in Korea.We've the Zenith skyscrapers are in a prime location right by the sea.

The requirements for building services in skyscrapers are particularly exacting: Pumps have to transport water over long distances and to great heights. To ensure that water comes out of the taps and rooms are properly heated even on the 80th floor, particularly reliable and high-performance pumps are called for. Wilo has the know-how and the products to meet the demands of high-rise construction – which is why Haeundae Doosan We’ve the Zenith is not the only high-rise construction project in Korea to use Wilo pump technology

The three skyscrapers with the eye-catching name occupy a prime location in Busan: Haeundae Beach, a popular destination for locals and tourists alike, is just a few minutes’ walk away. The city in southeastern Korea also enjoys a global reputation as an industrial location and is home to one of the world’s busiest container ports. With 3.5 million inhabitants, Busan is the second-largest city in the country after the capital, Seoul.
