Diary 216: Clean and healthy water in Vienna

This is the second day of our meeting in Vienna.

Last night, I learned the following interesting and important aspect of water supply in Vienna.

You can drink the water directly from the tap.

The authority in Vienna manages a wide forest area which supply clean and healthy water.

The hill water is filtered by the soil.

It is not treated with chemicals in the modern treatment plants.

The hill water is channeled to households and shops diretly.

We were at the restaurant last night (8 Nov 2010) and I asked for a glass of water.

The waiter just turned on the tap and passed me a glass of water.

The cold water from the tap is free at the restaurant.

However, if you asked for some hot water, you will be served in a pot.

Energy is used to boil the water.

The pot of hot water costs about $4 Euro at the restaurant.
