In 2023, the population connected to the urban wastewater collecting system in France was less than 56.26 million persons. Forecasts for 2024 to 2028 indicate a gradual annual increase, with an anticipated growth from 56.26 million to 57.0 million persons by 2028. The year-on-year growth rate is modest, indicating a steady but slow increase in the population relying on these systems.

Future trends to watch for include:

Technological advancements in wastewater management that may enhance capacity and efficiency.
Urbanization trends that could accelerate or decelerate these population connections.
Policy changes aimed at improving infrastructure investment could impact forecast accuracy.
