Built between 1901 and 1910 as the fourth reservoir of the territory, Kowloon Reservoir was the first reservoir built in Kowloon in response to the growing population of Kowloon Peninsula. The way in which water was provided for the Kowloon Peninsula was radically changed by the establishment of the Kowloon Reservoir. Rainwater impounded in the reservoir replaced well water and subterranean water pumped out by the Yau Ma Tei Pumping Station.
