Notas:
La Demanda Bioquímica y Química de Oxígeno y los sólidos en  suspensión se miden en (mg/l)        
   
   
 A partir del año 2006, no se publica el dato del 'volumen total de agua vertida' ya que  el cuestionario de la encuesta se ha modificado para incluir el destino final  de las aguas residuales depuradas  

 A partir del año de referencia 2004 se producen algunas variaciones  en los datos de los apartados de recogida y tratamiento de aguas  residuales debido a un cambio metodológico, con objeto de adaptarse a  las necesidades de los usuarios de estas estadísticas y a las  recomendaciones internacionales.  
 Se ha procedido a incorporar en estos apartados las aguas residuales  no procedentes de la red de distribución (pluviales, extracción  propia, u otras procedencias), mientras que hasta la estadística del  año 2003 inclusive, se recogía exclusivamente la información sobre  las aguas residuales procedentes de la misma.
