The Lower Peirce Reservoir (Chinese: 贝雅士蓄水池下段 Malay: Takungan Air Lower Peirce) is one of the oldest reservoirs in Singapore. It is located near MacRitchie Reservoir and Upper Peirce Reservoir. Previously known as Kallang River Reservoir or Peirce Reservoir, it was renamed Lower Peirce Reservoir after the creation of Upper Peirce Reservoir. It has a surface area of 6 hectares and the surrounding forest contains many trees that are over 100 years old. There is a Lower Peirce Trail, which is a 900-metre boardwalk that takes visitors through a mature secondary forest. The reservoir is the source of the Kallang River, the longest river in Singapore.

The Central Water Catchment, also known as the Central Catchment Area, is a designated planning area and one of the two main water catchments of Singapore. The country's main reservoirs – MacRitchie, Upper Seletar, Upper Peirce and Lower Peirce – are in the central catchment area.The Central Water Catchment lies in the geographical centre of the city, and is largely home to the Central Catchment Nature Reserve which houses several other recreational sites, including the Singapore Zoo, the Night Safari and the River Safari.

The Central Catchment Nature Reserve (Chinese: 中央集水区自然保护区; Malay: Hutan Simpanan Kawasan Tadahan Air Tengah; Tamil: மத்திய நீர்ப்பிடிப்பு இயற்கை ரிசர்வ்) is the largest nature reserve in Singapore, occupying 2880 hectares. Forming a large green lung in the geographical centre of the city, it houses several recreational sites, including the Singapore Zoo, the Night Safari and the River Safari, as well as several newer facilities built to encourage public appreciation of the reserve, such as the HSBC TreeTop Walk. The reserve sits within the boundaries of the Central Water Catchment. It is one of the four gazetted nature reserves in Singapore. The other three are the Labrador Nature Reserve which was gazetted since 1 January 2002, Sungei Buloh Wetland Reserve and Bukit Timah Nature Reserve. All four nature reserves along with the parks are protected under the Parks & Trees Act 2005. The nature reserve acts as a catchment area for the surrounding reservoirs. The country's main reservoirs – MacRitchie, Upper Seletar, Upper Peirce and Lower Peirce are located within the reserve.Most forests in the CCNR were cleared for logging and cultivation unlike Bukit Timah Nature Reserve, which remain relatively undisturbed. The CCNR now consists of a mixture of young and mature secondary forests with virgin primary forest surrounding the reservoirs.

Singapore Island, or Mainland Singapore, is the main constituent island of the sovereign island country and city-state of the Republic of Singapore. It is located at the southern tip of Malay Peninsula, in-between the Straits of Malacca and the South China Sea. The Singapore Strait lies to the south, while the Johor Strait lies to the north. The island forms the bulk of the country in terms of area, population and prominence, since areas situated on the country's smaller islands consists of military or industrial areas, with the exceptions being Sentosa as well as Ubin Island. As of June 2021, Singapore's population stood at 5.45 million and the mainland has a land area of approximately 710 square kilometres (270 sq mi).

The Straits Settlements were a group of British territories located in Southeast Asia. Originally established in 1826 as part of the territories controlled by the British East India Company, the Straits Settlements came under British Raj control in 1858 and then under direct British control as a Crown colony on 1 April 1867. In 1946, following the end of the Second World War and the Japanese occupation, the colony was dissolved as part of Britain's reorganisation of its Southeast Asian dependencies in the area. The Straits Settlements originally consisted of the four individual settlements of Penang, Singapore, Malacca, and Dinding. Christmas Island and the Cocos Islands were added in 1886. The island of Labuan, off the coast of Borneo, was also incorporated into the colony with effect from 1 January 1907, becoming a separate settlement within it in 1912. Most of the territories now form part of Malaysia, from which Singapore separated in 1965. The Cocos (or Keeling) Islands were transferred to Australian control in 1955. Christmas Island was transferred in 1958. Their administration was combined in 1996 to form the Australian Indian Ocean Territories.

Singapore was a British colony for 144 years, apart from a period of occupation under the Japanese Empire from 1942 to 1945 during the Pacific War. When the Empire of Japan surrendered to the Allies in 1945, at the end of World War II, Singapore was returned to British rule. The Straits Settlements were subsequently dissolved in 1946, and together with Cocos (Keeling) Islands and Christmas Island, Singapore became a separate Crown colony.The Crown colony was governed by the United Kingdom until it gained partial internal self-governance in 1955. Singapore subsequently gained full internal self-governance on 3 June 1959, at which point it became known as the State of Singapore. Singapore went on to merge with Malaya, Sarawak and North Borneo to form Malaysia on 16 September 1963, thereby ending 144 years of British rule on the island. On 9 August 1965, Singapore was separated from Malaysia to become an independent sovereign country, due to political, economic and racial differences.

It hosted races from 1961 to 1973 for automobiles under Formula Libre and Australian Formula 2 rules as well as for motorcycles. During the initial years, the main races for motorcycles and cars were 60 laps long. This was eventually refined into two separate races – a preliminary 20 lap event followed by a 40 lap event. The first Singapore Grand Prix of 1961 was won by Ian Barnwell in an Aston Martin DB3S while the first Singapore Grand Prix of post-independence Singapore in 1966, which also ran to Formula Libre rules, saw Singaporean Lee Han Seng win in a Lotus 22. The final victory went to Australian Vern Schuppan in a March 722 in 1973.

Lower Peirce Reservoir Park is a park located along Old Upper Thomson Road in Singapore and overlooks Lower Peirce Reservoir, Singapore's second oldest reservoir. A mature secondary rainforest lines the bank with numerous rubber trees and oil palms. A 900-metre boardwalk constructed in Nov 1998 provides an outdoor classroom for nature study and recreation in a natural forest environment. Interpretative boards on the flora and fauna in the forest serves as a guide together with bum rest, scenic view and picnic points along the route. The boardwalk was specially routed and built on existing trails to elevate the compaction and soil erosion caused by the overuse of these trails in the forest to ensure the protection floral and fauna on the forest floor.
