π§ γKowloon Reservoir (δΉιΎζ°΄ε‘)γ is one of the earliest completed waterworks engineering projects in Hong Kong. Located within Kam Shan Country Park in the Sha Tin District of the New Territories, it was officially commissioned in 1910. The complex comprises the main reservoir, a bywash reservoir, and a reception reservoir that intercepts mountain streams along Tai Po Road. With an initial capacity reaching 3 billion gallons, it significantly alleviated the acute water shortages plaguing the Kowloon Peninsula at the time. Its iconic curved gravity dam, constructed from granite blocks, remains fully operational today. In 2009, five of its historic structures were declared statutory monuments of Hong Kong, standing as a testament to the achievements of early hydraulic engineering.

Nurtured by the lush woodlands around the reservoir cluster, Kam Shan Country Park has become the most densely populated habitat for macaques in Hong Kong, and visitors frequently spot monkey troops along the roadsides and dam crests. Furthermore, the remnants of the wartime Jubilee Battery and the path of MacLehose Trail Section 6 traverse the landscape, anchoring both ecological conservation and historical memory in one space. Facilities like the reservoir jogging trail and designated barbecue areas also make this a highly popular choice for weekend leisure. —
π Historical Background & Development
- π°οΈ Construction Era: Construction commenced in 1901 and concluded in 1910. It is the fourth reservoir built in Hong Kong and the very first located in the New Territories.
- π Reason for Construction: In response to a surging population across the Kowloon Peninsula, existing wells and pumping stations fell short of demand, prompting the government to construct a reservoir system to store rainwater.
- ποΈ Water Supply Revolution: The Kowloon Reservoir served as the source for the “Kowloon Gravity Fed Water Supply System,” marking a major milestone in Hong Kong’s water engineering history.
- ποΈ Subsequent Expansions:
- In 1922, the dam was raised to 100 feet, expanding storage capacity by 1.5 million gallons.
- In 1926, the Kowloon Reception Reservoir (historically known as Eption Pond) was completed.
- In 1931, the Kowloon Bywash Reservoir (commonly called the New Pond) was commissioned.

𧱠Architectural Features & Statutory Monuments
Five structures within the Kowloon Reservoir cluster were designated as Statutory Monuments of Hong Kong in 2009:
Monument Name Year of Completion Function & Characteristics Main Dam 1901β1910 An iconic, gracefully curved masonry structure. Main Dam Valve House 1901β1910 Regulates water flow and channels supply downstream. Spillway Dam 1901β1910 An overflow facility designed to safely discharge surplus water. Spillway Dam Recorder House 1901β1910 Monitors water levels and discharge flow rates. Recorder House 1901β1910 Houses hydrological telemetry equipment and records. A historical curiosity: Rhesus macaques were deliberately introduced to the surrounding woodlands to forage on the fruits of the toxic Strychnos axillaris vine, inadvertently giving rise to the reservoir’s famous wildlife spectacle.

π§ Structure & Capacity of the Kowloon Reservoir Cluster
Reservoir Name Year of Completion Storage Capacity (Million mΒ³) Main Dam Length / Height (m) Kowloon Reservoir 1910 1.578 182.9 / 33.2 Kowloon Bywash Reservoir 1931 0.800 106.0 / 41.1 Kowloon Reception Reservoir 1926 0.121 70.1 / 13.0 Shek Lei Pui Reservoir 1925 0.374 83.5 / 22.3
- π§οΈ As Kowloon Reservoir sits at the highest elevation, rainwater initially fills the main reservoir before being managed and channeled down to the bywash and reception reservoirs.
- π§ In 2019, the Drainage Services Department initiated the construction of a 2.8 km water tunnel linking the Bywash Reservoir to the Lower Shing Mun Reservoir to curb overflow issues during heavy rainstorms.

π§ Modern Functions & Flood Mitigation Engineering
Due to the modest storage limits of the Kowloon Reservoir cluster, heavy downpours historically caused frequent overflows, resulting in localized flooding in Cheung Sha Wan. To address this, the government executed a major infrastructural intervention:
π οΈ 2019 Inter-Reservoir Transfer Scheme
- The project involved boring a 2.8 km long water tunnel with a 3-metre diameter.
- By connecting the Kowloon Bywash Reservoir to the Lower Shing Mun Reservoir, it successfully minimizes overflow spills while boosting overall water harvest.
- The total engineering cost reached approximately HK$1.22 billion, with construction wrapping up in 2022.
- The system yields an additional 3.4 million cubic metres of local rainwater collection annually.
