Sha Tin is the largest secondary sewage treatment plant in Hong Kong. Relocation to caverns would release the existing site of about 28ha for housing and other purposes.
Speaking after the signing ceremony, director of drainage services Chan Chi-chiu pointed to the department's experience gained in the construction and operation of Stanley Sewage Treatment Works. He said that the department is confident that the relocation of Sha Tin Sewage Treatment Works to caverns will bring extended benefits to the community and environment of Sha Tin.
The scope of the two-year study comprises technical and impact assessments, ground investigation, preparing an outline design for engineering works, formulating implementation strategies and programmes and public engagement.
The study will review the suitability of nearby Nui Po Shan of A Kung Kok as the cavern site. It will also involve a planning review of the future land use of the existing Sha Tin Sewage Treatment Works site to establish a business case for the relocation project.
