Ngong Ping Sewage Treatment Works (NPSTW) was commissioned in 2006, and was the first tertiary sewage treatment plant with reclaimed water facilities in Hong Kong. NPSTW is located in the Shek Pik Reservoir catchment area and surrounded by country parks, which is an environmentally vulnerable area. In designing the facilities, we had also included the greening concept.
NPSTW has a fish pond with aquarium fishes. The fishes are reared by the reclaimed water from the facility.
