Could you imagine half a city-state soaking up rain like a giant sponge, where no water goes to waste? In Singapore it is not an imaginary scenario, it’s an amazing fact.
The creativity of the idea originates back to the mid 1980’s, when Singapore’s clean water crisis forced its people to become creative. The raindrops fell in abundance, but there was no evident way to capture them efficiently. Soil contamination made things even harder.
In its effort to exploit the 94 inches of rain falling every year, Singapore has a developed a plan to capture, save and recycle the water. The built-in runoff water capture systems existing in Singapore nowadays offer multiple benefits: reduced water purification costs and a healthier planet.
A classic example of this recycling method is located in the Changi Airport. It is estimated that 33% of the water used in this airport is the result of the reservoir captured and recycled rainwater. The airport is impressively said to save more than $275,000 annually from this pioneering model.
With the lack of water crisis expansion over time, countries wishing to have any hope of avoiding a water crisis should start thinking creatively, just like Singapore.
