Arup has been appointed as principal designer to the Veolia-Leighton-John Holland joint venture (JV) to construct the world’s largest sludge treatment works in Hong Kong, due to open in 2013.
Arup was the JV’s civil, structural, geotechnical and power generation designers during the tender stage, with engineers from Hong Kong, UK and Australia being influential in developing the project’s striking architectural design.
The sludge treatment plant will be commissioned in 2013. The waste water sludge, mainly collected from Stonecutters Island Sewage Treatment Works, the largest treatment facility in Hong Kong (also with Arup as its consultant), will be incinerated by fluidised bed incinerators. It will evaporate all of the water content in the sludge and burn 90% of the remaining solid component, thus the capacity required in landfills for sludge disposal will be greatly reduced.
The facility will provide Hong Kong with an iconic landmark building that is respectful of its environment. It will be entirely self sufficient; generating and exporting power to the regional electricity grid and processing sea water through a desalination plant. Rainwater will be collected for non-potable use, and waste water will be treated and re-used on site with a very low impact on the environment.
“This is an extremely important win for Arup,” said Arup’s East Asia Energy, Resource and Industry Leader Fergal Whyte.
“We are proud to help Hong Kong deliver its commitment to developing a sustainable economy with state-of-the-art sludge treatment facilities.”
