“Relocation of Sha Tin Sewage Treatment Works to Caverns” Thematic Exhibition

To enable the public to gain a better understanding of the project of “Relocation of Sha Tin Sewage Treatment Works (STW) to Caverns”, the Drainage Services Department (DSD) will hold the thematic exhibition at City Gallery from 2 December to 30 December 2020. Through videos, display panels, computer games and physical model, the thematic exhibition will introduce the project’s latest development and innovative technology applied. At the same time, to complement the thematic exhibition, DSD will be organizing online seminar on 12 and 13 December 2020 to introduce the latest development and the application of innovative technology of the project and the daily operation of the existing Sha Tin STW, the largest STW in Hong Kong, and Stanley STW, the first STW built in cavern in Hong Kong, so as to facilitate the public to understand the benefits of housing the STW in the cavern and the operation of the STW.

There is a pressing need to increase land supply for various uses by sustainable and innovative approaches to support social and economic development in Hong Kong. Rock cavern development is one of the feasible approaches to release our land resources. The Sha Tin STW is earmarked for relocation to a number of caverns to be excavated in Nui Po Shan opposite Shing Mun River. Sha Tin STW is the largest secondary STW in Hong Kong. Its relocation to caverns could release about 28 hectares of land on the existing Sha Tin STW site for other uses that benefit the public and improve the living environment of the district.

The future Sha Tin STW relocated in a cavern complex will be the largest of its kind in Hong Kong. The relocation plan will be implemented by stages, including site preparation and access tunnel construction, main caverns construction and upstream sewerage collection works, sewage treatment facilities installation, as well as decommission and demolition of the existing Sha Tin STW.
