When conducting the review of the proposed relocation site, the feasibility study consultant has identified a nearby site suitable for cavern development assessment for the existing STSTW, including Nui Po Shan of A Kung Kok, Shek Mun, Ma On Shan, Kau To
Shan South and Kau To Shan North.

The feasibility study has confirmed that Nui Po Shan of A
Kung Kok is the best site for the relocation of the STSTW. The
methodology and result of the review have been examined by an
independent expert panel composed of three professors from
the Hong Kong University of Science and Technology. To
sum up, Nui Po Shan of A Kung Kok site has the
following favourable conditions:

	The geology of this area, belonging to hard granite with no obvious weak zones and faults, is most suitable for construction of large caverns
	The selected site is located in the proximity of the existing STSTW and effluent export tunnel (which conveys the treated effluent from the STSTW to Kai Tak River in Wong Tai Sin for discharge). As such, relocating the STSTW to this area will minimize the effect on the upstream sewerage and the downstream disposal network, thereby minimizing the disturbance to the whole Sha Tin District, reducing the construction and operation costs and shortening the construction period
	As majority of the area belongs to government land, the relocation project does not involve large extent of private land resumption
	The overall community and environment will be enhanced after the relocation of the STSTW
	With appropriate measures, the traffic impact due to the relocation of the STSTW could be minimized
