The significant increase in the amounts of drinking water supplied and wastewater collected in 2010 was largely attributable to the
operational start-up of new and integrated infrastructures, as shown in the following table:

As regards infrastructures, there was significant progress in expanding the number of pumping stations (+600), the size of the supply and
drainage networks (+3,830 and 2,061km, respectively) as well as a sharp rise in the water collection sources (+256), largely due to the
work of AdRA - Águas da Região de Aveiro and AgdA - Águas Publicas do Alentejo, which launched its operational activities in 2010.
The UNA-PD companies charged significantly different tariffs, due mainly to the amount of investment involved and the size of the
population served (population density and orography have a significant impact and can require larger investments) as well as in the
