What you should know about Barcelona water supply

Where does Barcelona’s water come from?

The first thing to consider when determining water quality in any city is the water’s source. In Barcelona, the city main tap water supply comes from two rivers: the Ter and the Llobregat.

The Llobregat, which supplies the city with the majority of its water, has very high levels of minerals such as potassium and magnesium.

Because the river passes through a very salty region northwest of Barcelona near the town of Súria, the water fro the Llobregat tastes much better in areas before the river reaches Súria.

Afterwards, it takes on a very salty taste. Barcelona does have desalinization plants, but they can only handle about 20% of the city’s water demand and are very expensive to operate.

The bad taste of the water in Barcelona comes from the high salt levels, the osmosis process the water goes through to remove some of the salt, and the high levels of chlorine used to protect it from contamination.
