Notas:
Para la variable 'Longitud de la red de alcantarillado' solo se publica el dato nacional. Los datos por comunidad autónoma  no se publicarán, hasta tanto no se disponga de una serie temporal representativa que permita hacer una estimación no  afectada por la variabilidad de los factores de elevación de la encuesta.
