In 2023, Spain had the largest population not connected to urban wastewater treatment, followed by Serbia and Kosovo. Notably, there were significant variations, with countries like Spain, Kosovo, Poland, and Croatia showing an increase in unconnected population, while Bosnia and Herzegovina, Bulgaria, and several others registered declines. Lithuania, Ireland, and Slovakia particularly saw sharp decreases. Over the past five years, the cumulative average growth rate highlights varying levels of commitment or infrastructural developments across European countries, leading to these disparities.
Future trends to watch include the continued efforts in infrastructural development and environmental compliance aimed at reducing the unconnected population, especially in countries with higher numbers like Spain and Serbia. The increase in connected populations in countries like Poland and Croatia indicates a positive trend towards improvement. Additionally, the European Union's directives and financial support might further minimize disparities across regions.
