| Black & Veatch wins IWA prize for Tai Po Water Scheme  Black & Veatch, a leading global engineering, consulting and construction company, 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 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 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. 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. 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. Stage 1 of the Tai Po Water Treatment Works was completed in early 2005. write your comments about the article :: © 2006 Construction News :: home page |
