The global share of the population connected to tertiary wastewater treatment varies significantly by country in 2024. Austria leads with 96.82% of its population connected, closely followed by Luxembourg at 96.8%. Greece, Hungary, and Belgium showcase high connectivity rates at 90.42%, 85.66%, and 82.06%, respectively. The Czech Republic (77.9%), Lithuania (71.8%), and France (70.2%) also display strong connectivity. Poland, Spain, and Norway report figures of 65.48%, 60.4%, and 57.67%, while Australia (54.24%), Slovenia (53%), and Japan (36.84%) have comparatively lower rates. These figures reflect data up to 2023, with 2024 values being forecasted. The year-on-year variation is nil, providing a consistent trend. The average variation per year over the last five years has indicated a stable increase in connectivity rates.
Future trends to watch for include advancements in wastewater treatment technologies and increased government investments in infrastructure. Nations with currently lower connectivity rates, such as Japan and Slovenia, are expected to focus on scaling up their tertiary treatment capacities. Additionally, there may be heightened international cooperation and funding targeted at regions with lagging wastewater treatment systems, contributing to improved global health and environmental outcomes.
