Project background

 

VW-VES (HK) Limited won the design-build-operate contract for a state-of-the-art sludge treatment plant located in Tseng Tsui, Tuen Mun of Hong Kong in 2010.   The company, jointly own by Veolia Environmental Services and Veolia Water will undertake the following 15 years of operation upon its completion.    

The facility is equipped to treat a maximum of 2,000 tonnes of sludge a day from Hong Kong’s 11 wastewater treatment plants, hence reducing  volume of sludge by 90% and pressure on the landfills of Hong Kong.

 

Major facilities

 

  • Sludge treatment
  • Environmental Education Centre, including an Exhibition Gallery and Visitors’ Gallery
  • Recreational facilities, i.e. Heated Pools, Landscaped and Ecological Gardens
  • Other facilities, such as: Conference Room and Lecture Theatre 

 

VES Excellence

 

  • The world’s largest wastewater sludge treatment plant; totally autonomous for its water and electricity needs, surplus electricity will be exported to the power grid;
  • Main structures and equipment of the plant includes: steam-producing incinerator boiler furnaces, turbines to convert the steam into electricity and flue gas treatment system that comply with the European Union strictest emission standards, a seawater desalination plant will be used to produce process and potable water for internal use;
  • Wastewater produced will be recycled on site using advance processes, no discharges of effluent into the sea will be made;
  • The wave-form and streamlined architectural design of the facility reflects the seaview in front and ridge lines at the back, which serves to integrate the plant into the surrounding landscape;
  • Natural ventilation and lightings are adopted to save energy consumption.
