The Fort Canning Service Reservoir (Chinese: 福康宁备水池) is an underground reservoir located on top of Fort Canning Hill in Singapore. Construction of the reservoir began on 1 April 1927 on the former site of a large artillery barracks and parade ground to help supplement the large impounding reservoirs. The reservoir was constructed in two sections, the southern section was ready for water storage by 1 August 1928, and the final work completed by the middle of January 1929. Water is pumped from the large reservoirs into the service reservoirs, thus enabling water to flow down the hill into houses.
