Located on Cheung Chau Island in Hong Kong, the Drainage Services Department is enhancing the capacity of the existing Cheung Chau Sewage Treatment Plant and upgrading its treatment level to secondary standards, while also increasing the capacity of the existing North Shek Pumping Station. To provide a comfortable working environment for on-site staff, a new site office has been established.

This two-story Cheung Chau site office is constructed using the Modular Integrated Construction (MiC) method, featuring factory prefabrication and on-site assembly, significantly reducing both time and costs.
