The Aberdeen Reservoirs (Chinese: 香港仔水塘) are a group of two reservoirs, consisting of the Upper Aberdeen Reservoir (Chinese: 香港仔上水塘) and the Lower Aberdeen Reservoir (Chinese: 香港仔下水塘), in Aberdeen, Hong Kong.
The Aberdeen Reservoirs were built to augment Pok Fu Lam Reservoir in providing water supply to the west of Hong Kong Island. The Lower Aberdeen Reservoir, with a capacity of 44.2 million imperial gallons (201,000 m3), was originally a private reservoir owned by Tai Shing Paper Factory, built in 1890, which also provided water to nearby residents. The Government bought the reservoir at a price of HK$460,000 and expanded it to a capacity of 91 million imperial gallons (410,000 m3). At the same time, the Government built a new reservoir with a capacity of 175 million imperial gallons (800,000 m3) above the original one, increasing the total capacity to 266 million imperial gallons (1,210,000 m3). The reservoirs were officially opened on 15 December 1931 by Governor of Hong KongWilliam Peel, becoming the fourth and last reservoir group ever built on Hong Kong Island, after Pok Fu Lam, Tai Tam and Wong Nai Chung.
