BLACK & VEATCH EARNS IWA GLOBAL GRAND PRIZE FOR DESIGN
OF TAI PO WATER TREATMENT WORKS AND AQUEDUCTS
Hong Kong (September 15, 2006) – Black & Veatch has earned the Global Grand Prize in the Design category of the International Water Association (IWA) Project Innovation Awards for the Tai Po Water Treatment Works and Aqueducts project in Hong Kong, China.
The award, which recognizes excellence and innovation in water engineering projects throughout the world, was presented to Black & Veatch on September 12 at the 2006 IWA World Water Congress and Exhibition in Beijing. The company was also awarded the Regional Prize Winner in the Europe (and Rest of World) region for design of the Tai Po Water Treatment Works and Aqueducts.
Black & Veatch provided innovative solutions as consulting engineers for the significant water treatment works project in Hong Kong, one of the world’s most densely populated and rapidly developing areas. The global engineering, consulting and construction company worked closely with the Hong Kong Water Supplies Department to incorporate space-efficient technologies in its design of the Tai Po Water Treatment Works, Pumping Stations and Aqueducts (Stage 1). The new facilities, which currently provide water treatment capacity of 250,000 cubic meters a day and include 12 kilometers of aqueduct tunnels, were designed to an ultimate capacity of 1,200,000 cubic meters a day on a small hill-side site that posed sizeable design and construction challenges.
“The plant is complete and operating very satisfactorily, providing a good quality treated water,” said Chan Chi-chiu, Director of Water Supplies for Hong Kong. “We are proud to have this facility as a key contributor to the overall provision of Hong Kong water supplies.”
Black & Veatch’s involvement in the planning and development of a supplemental water supply for the metropolitan areas of Hong Kong and Kowloon began in 1994 with a study of options and has continued through pilot testing and detailed design and construction supervision of Stage 1. Tai Po was selected as the location for the facility because of its proximity to the raw water supply system. However, due to Hong Kong’s large population and high land value, the site for Tai Po Water Treatment Works was relegated to a small hill-side area. During the development of the project, the available area was modified and reduced to accommodate the Fung Shui requirements of the local villages.
The difficult terrain required a shift in conventional thinking. By designing a stacked configuration of equipment based on successive treatment stages and effectively utilizing advanced small-footprint technologies, Black & Veatch enabled development of a major infrastructure asset on land with little value for normal urban development.
Space-efficient technologies introduced in the design of the Tai Po Water Treatment Works include aerated biological filtration for ammonia removal – which considerably reduced chlorine usage – and dissolved air flotation (DAF). The application of DAF for water clarification is much more efficient and operates within a smaller footprint than traditional sedimentation methods. The project marked the first use of DAF on a major treatment works in Hong Kong.
“This is another example of our global technology and practice leaders working closely with experienced project teams and world-class owners to apply the best possible solutions locally,” said Dan McCarthy, President and CEO of the water business of Black & Veatch.
Although the Water Supplies Department initially sought a new water treatment works with an ultimate capacity of 800,000 cubic meters a day, Black & Veatch professionals were able to increase capacity by 50 percent, to 1,200,000 cubic meters a day. Use of a modular design will allow the works to be expanded as needed.
Stage 1 of the Tai Po Water Treatment Works was completed in early 2005.
IWA Project Innovation Award entries were judged on their original or innovative application of new or existing technology; future value to the water engineering profession; social, economic and sustainable design considerations; complexity of the problem or situation addressed; and performance in exceeding client/owner needs.
