The population in Germany connected to wastewater treatment has been steadily increasing from 80.64 million in 2013 to 83.7 million in 2023. This represents a gradual year-on-year growth, with noticeable annual increments, such as a 0.87% rise in 2015. The compound annual growth rate (CAGR) displays a decreasing trend, shrinking from 0.51% in 2016 to 0.19% in 2023. Forecasts suggest a continued increase, reaching 84.44 million by 2028, though the growth rate is expected to slow further, evidenced by a forecasted 5-year CAGR of 0.14% towards 2028.

Future trends to watch for:

Implementation of new environmental regulations could further boost connectivity rates at an accelerated pace.
Technological advancements in wastewater treatment may alter trends by improving efficiency and coverage.
Socio-economic factors and urbanization levels will continue to influence the population connectivity to wastewater systems.
