The expansion of Tai Po Water Treatment Works (WTW) Project aims to enhance the reliability and flexibility of the water supply and distribution system. Tai Po WTW was designed to develop in various stages comprised of 3 streams, each with a capacity of 400,000cubic meters/day, to a total capacity of 800,000cubic meters/day upon completion of the Project. The ultimate capacity can be upgraded to 1,200,000cubic meters/day in its future expansion.
China State - ATAL Joint Venture was engaged in the design and building of a new Stream to expand the Tai Po WTW and ancillary raw water and fresh water transfer facilities. ATAL also provided electrical and mechanical (E&M) engineering services from design, supply, installation to testing and commissioning of the whole water treatment plant. Dissolved air flotation, aerated biological filtration and rapid gravity were deployed as the three main treatment processes to ensure the treated water in compliant with the World Health Organisation’s Guidelines on Drinking Water Quality. In addition, the expansion has incorporated ozonation for further water quality improvement.
Tai Po WTW has adopted an innovative design approach and incorporated various sustainable features for optimisation of the plant operation. Moreover, as the Project involved many sophisticated processes and techniques. Building Information Modelling (BIM) was applied in the work process for real time monitoring so that corresponding remedial action could be taken.
