Fresh Drinking Water From The Sea

As mentioned in an earlier post about the rainfall in Aruba, this island is very dry. Rainfall is average 16.2 inches/44 centimeters per year. Being a volcanic island (meaning: this island came about an underwater volcanic eruption a long time ago) and also a coral island, there is no water source under the ground. A major conundrum: how do you get your fresh drinking water? The title gave it away: from the sea. The body of water that surrounds Aruba is the very salty Caribbean Sea and the only source of Aruba’s fresh drinking water.

According to international organizations, Aruba’s drinking water ranks among one of the best in the world. It can easily compete against any fancy brand of bottled water. “Tap water is pure distilled water filtered through a bed of coral rocks where it absorbs important minerals such as calcium, and oxygen,” according to Aruba’s water company’s information site.

How come it is so good? The water company: “The World Health Organization’s standard for dissolved salt is 600 parts per million (ppm). Aruba’s water contains between 5 and 15 ppm of salt which is 40 times better.” Furthermore: “The quantity of bacteria is consistently below detectable levels, in other words, a very high level of purity.”

The core machinery uses fossil fuel, namely gas-oil or better known as diesel. The desalinization process is a very extensive and expensive one. When oil prices keep rising the water bills go up, too.

I have an information booklet with drawings on how exactly the purification process works. In a later post I’m going to scan it and publish it for you. Stand by for that.
