Relocation of Sha Tin Sewage Treatment Works to Caverns

Improve the Environment and
Control Odour Impact

Major facilities are hidden inside caverns,
integrating with the surrounding environment
Caverns serving as natural barriers,together
with appropriate odour control
measures and ventilation shafts
at a remote location on the
hill, will effectively
resolve the odour issue
Enhance Service

Upgrade sewage treatment facilities and
adopt advanced sewage treatment system
Minimize the footprint and enhance
operational efficiency
Enhance the Community
Develop new land resources
Balanced development considering
community needs
Prepare for the Future
Long term planning for the aging STSTW
Different scale of rehabilitation will still
be required for the existing facilities
if STSTW is not relocated
Reuse Treated Effluent
Investigate to further treat a portion of
effluent as reclaimed water for non-potable
uses in the plant
