Themed Water Gathering Grounds

The programme explores the interactive relationships between water and ecology with the public in three selected Water Gathering Grounds in Hong Kong.

Shing Mun Reservoir

Constructed from1923
Completed in1939
DistrictTsuen Wan District
Total surface area of the Water Gathering Ground Around 2,480 hectares
ValleyShing Mun Valley
NicknameJubilee Reservoir
DamsGorge Dam, Pineapple Pass Dam, Low Gaps Dam
Water catchmentAround 30 million m³ per year
CapacityAround 13 million m³
Ranking by capacity5th in Hong Kong
Cost spentAround HKD 9.5 million

With the magnificent landscape and brilliant accessibility, Shing Mun Reservoir tops the travel bucket list for holiday excursions. Construction of the reservoir commenced in 1923 and ended in 1939 after going through three successive phases of work. Shing Mun Reservoir and Lower Shing Mun Reservoir then become the first source in the peninsula distributing stored water to Hong Kong Island.

The history of Tai Tam Reservoirs dates back more than a century. Twenty-one of the water works are declared monuments, with unique architectural and historical value, helping make this popular with visitors from Hong Kong and overseas.

Work on the Tai Tam Reservoirs began in 1883, and was expected to be completed in four phases. Notwithstanding financial shortages, the project was completed in 1917. Unfortunately, during the Second World War, the woodland of the catchment area was largely burnt down and logged. What we see today is secondary forest.

Tai Tam Reservoirs were specially designed with four reservoirs in a group. When the upper reservoirs are full, water will overflow to the lower reservoirs, thus increasing the total capacity of water supplies for Hong Kong island.

Plover Cove Reservoir

Plover Cove Reservoir
Constructed from 1961
Completed in 1968
District Tai Po District
Total surface area of the Water Gathering Ground Around 3,220 hectares
Cove Plover Cove
Dams Main Dam, Three Subsidiary Dams, Spillway
Water catchment Around 75 million m³ per year
Capacity Around 230 million m³
Ranking by capacity 2nd in Hong Kong
Cost spent Around HKD 407 million

Plover Cove is originally a tranquil crescent bay with a few small islands sitting across. Before the reservoir was built, the place had long been priced as a nourishing ground for the harvest of pearls and marine fishes.

The first of its kind in the world, Plover Cove Reservoir was a big engineering project – reclaiming the sea with dams connecting the islands and the cove to form a large freshwater reservoir.

Plover Cover Reservoir stores rainwater collected in the catchment as well as freshwater imported from the East River (Dongjiang) in China. Plover Cover Reservoir, together with High Island Reservoir, ranks second and first in terms of capacity respectively. The two reservoirs play a strategic role in Hong Kong. In the worst-case scenario when unforeseeable water crisis happens, the two reservoirs can provide sufficient portable water for the people of Hong Kong over a period of four to six months.
