Walk around Singapore: Sembawang hot spring - May 2016

May Day went cycling with my friends in the Sembawang and Seletar areas and dropped by the hot spring.

Beware: Hot spring water may be good for your health, but beware that the hot water may burn your skin, especially those with chronic illnesses or insensitive skin

Water is so hot it can cook eggs

How the Sembawang hot spring was formed

According to Dr Grahame John Henderson Oliver, a senior lecturer at the Nanyang Technological University's Asian School of the Environment, the hot spring’s formation is linked to Bukit Timah Hill.

At 165 metres, the hill is the highest point in Singapore and when rain falls, the rainwater seeps through the granite within the hill.

The rainwater then sinks to about 4.8 kilometres underground, where it gets heated up by the surrounding rocks and mantle to about 160 degrees Celsius and 190 degrees Celsius, he explained.

As more rain falls, the water underground is pushed out through the faults and cracks that connect the ground under Bukit Timah Hill and the Sembawang Hot Spring, he said. The water then cools to 70 degrees Celsius as it reaches the surface.
