Siu Sai Wu, Reservoir in Sham Shui Po, Hong Kong, China

Siu Sai Wu is an artificial reservoir built by the Water Supplies Department in a ravine between Beacon Hill Road, Cornwall Street and Lung Cheung Road in Kowloon Tong. It consists of two lakes at different levels, about 20 feet deep, whose layout resembles Hangzhou's West Lake and gave the site its name. Most of the area is enclosed by Water Supplies Department fencing and dense vegetation.

Siu Sai Wu was an artificial reservoir built by the Hong Kong Waterworks Office in the valley between Beacon Hill Road, Cornwall Street and Lung Cheung Road, supplying water for flower watering and flushing in Kowloon Tong. It had two lakes at different levels, fed by an underground channel linked to the Tsim Sha Tsui railway station. The reservoir was decommissioned in 1972 and has stood unused since, no longer under the Water Supplies Department.

The name comes from its resemblance to Hangzhou's West Lake, with two tiers of pools among pines. In 1937 the Nam Wah Athletic Association ran a 50-person trip here, and Kowloon scouts held their first large camp in 1939. Today dense fencing hides the pools, and walkers see only the overflow spilling from the dam.

The site is fenced off with an 8-foot wire fence and dense vegetation, so access is not possible; the only view is from the downstream entrance on Cornwall Street, where overflow from the lower lake forms a small waterfall. The nearest MTR station is Kowloon Tong on the East Rail and Kwun Tong lines.

The reservoir was built by the Water Supplies Department as an artificial storage tank about 20 feet deep, supplying water for flower watering and toilet flushing in Kowloon Tong, with an underground channel linking it to Tsim Sha Tsui station. It has two lakes at different levels, and its name comes from a resemblance to West Lake in Hangzhou, Zhejiang.
