The Harbour Area Treatment Scheme (HATS) was honoured with the 15th Tien-yow Jeme Civil Engineering Prize in the Municipal Engineering category.
The award is the top honour for civil engineering and construction in China. Established by the China Civil Engineering Society and the Beijing Tien-Yow Jeme Foundation for Development of Science and Technology in Civil Engineering, the prize commends engineering projects with outstanding achievements in technological innovation and application.
The only Hong Kong winner this year, HATS is the city’s largest environmental infrastructure project, with the objective to improve the water quality of Victoria Harbour by collecting and treating sewage generated from both shores. The project comprises two stages, with construction works spanning over two decades.
Arup’s work in HATS Stage 2A – upgrading the Stonecutters Sewage Treatment Works and eight preliminary treatment works on the Hong Kong Island – was critical in the successful commission of the Scheme. As the project consultant, we were responsible for civil, structural, electrical and mechanical, process, environmental, control and automation engineering, as well as the overall project management and implementation. This included building one of the world’s largest underground pumping stations measuring 55m in diameter, 40m deep with a capacity of 32m3/s, and a 260m interconnection tunnel connecting to the existing pumping station, within the tight 10.6ha sewage treatment plant.
Following the commissioning of the HATS Stage 2A, Hong Kong’s annual cross harbour swimming race returned to the original route from Tsim Sha Tsui to Wan Chai for the first time this year (2017), a move made possible by the improved water quality of the harbour.
