In 2023, Belgium generated a total of 558 million cubic meters of urban wastewater. The forecasted data from 2024 to 2028 shows a steady decline in wastewater generation year-on-year. Specifically, the figures are 556.19 million cubic meters in 2024, 554.37 in 2025, 552.6 in 2026, 550.86 in 2027, and 549.15 in 2028, indicating a consistent downward trend.
Year-on-year percentage variations are as follows:
- From 2023 to 2024: approximately -0.6%
- From 2024 to 2025: approximately -0.3%
- From 2025 to 2026: approximately -0.3%
- From 2026 to 2027: approximately -0.3%
- From 2027 to 2028: approximately -0.3%
Over the last two years, the average yearly decrease (CAGR) is around -0.3% per year.
Looking forward, it is essential to watch trends related to urban population growth, water conservation measures, and the efficiency of wastewater treatment technologies. These factors could significantly impact the volume of urban wastewater generated in the future.
