Jardine Engineering Corporation (JEC) designed and constructed a reclaimed water treatment plant for the Environmental Protection Department (EPD) at Shek Wu Hui Sewage Treatment Works (STW).
The contract was to build a 150 m3/day reclaimed water treatment plant at Shek Wu Hui STW. The project demonstrated that high quality treated water can be produced using membrane technology and disinfection.
The works, which commenced in April 2006 and were completed at the end of 2008, included Pumping and Conveyance Systems, Chemical Storage and Dosing Systems, Ultrafiltration Membrane Filtration System, and a Disinfection System. The focus for the design of the plant was to maintain consistent water quality performance and to enable the plant to operate cost-effectively once constructed.
Uses of Reclaimed Water
The reclaimed water is used by three local schools, an elderly home and domestic dwellings near the Shek Wu Hui STW for non-potable applications, such as irrigation, toilet flushing, and fish pond filling. Data and feedback collected from end users have provided a valuable database for the consideration of a full scale reclaimed water treatment scheme in the future.
Reclaimed water has been widely used in other countries but in this project JEC introduced the technology to Hong Kong for the first time.
