In 1863, the Pok Fu Lam Reservoir and the first water main from Pok Fu Lam Reservoir to Bonham Road was built. However, the storage capacity of the reservoir was reduced from the original 30 million gallons to 2 million gallons (equivalent to 9,000 m3). The Pok Fu Lam Reservoir could at best provide 4 days of water to the community. Once completed the reservoir was found to be grossly inadequate. In 1871 the expansion project of the Pok Fu Lam Reservoir was commenced. In 1877, after the completion of several expansion projects, the reservoir’s capacity had increased to 68 million gallons, which was 34 times of its capacity originally built.
