Ninety-one percent of Spanish households are connected to public water supply networks.
Over 57 percent of the raw water (surface and groundwater) used for drinking water requires heavy
treatment, but only 33 percent of supply actually undergoes such treatment.
All municipalities of over 20,000 people have a sewer system, but only 60 percent of the population is
connected to wastewater treatment systems.
About 75 percent of the sewer systems carry sewage and rainwater runoff.
