Did you know that if you have five or more people registered at your address, you can get a ~10% discount on your water bill? Well, you do now. Just head over to the friendly Sorea office near Torreblanca and they will help you out.
It doesn’t really matter who is registered, as long as they can phone and check the headcount with the townhall. Even if it’s your illegal South American housekeeper. Or you could get your friends from the US to empadronamiento at your place when they are visiting.
