Reservoirs, rainwater, and machines between hills and sea
Hong Kong hides engineering between hills and sea: 108 stone columns hold up a circular reservoir, a bay became freshwater, stormwater waits beneath playing fields, and trams still pass through a street market.

A ring of arches opened under the hill
Beneath Bishop Hill, 108 stone columns support a circular former service reservoir.
Beneath a hill used for morning exercise lies the former Sham Shui Po Service Reservoir, completed in 1904. The circular tank held 9,900 cubic meters; brick arches transferred the concrete roof’s weight to 108 granite columns.
From the dam, sea lies on one side and fresh water stored in a former bay on the other.
Plover Cove Reservoir is not a basin dug in the mountains. Engineers built a long dam across a bay entrance, excluded seawater, and turned the inside into fresh-water storage.
Eleven playing fields stay in use while 60,000 cubic meters of stormwater waits underground.
Games continue above; during a downpour, the underground shift begins. Beneath Happy Valley Recreation Ground is a 60,000-cubic-meter stormwater tank, roughly equal to 24 standard swimming pools.
When a North Point tram turns into Chun Yeung Street, produce stalls yield half a step to the rails.
A tram turns from broad King’s Road and Chun Yeung Street instantly narrows. Awnings reach toward the track; vegetables and fresh fish nearly touch the car.
