Based on the data for fresh groundwater abstraction for public water supply in Germany, the value for 2023 is not provided for comparative analysis. However, from the forecasts, there is a steady increase in abstraction from 2024 through 2028, beginning at 3.79 billion cubic meters in 2024 and reaching 3.84 billion cubic meters by 2028.

Year-on-year percentage increases are slight but consistent, with increments of 0.26% to 0.53% each year, indicating a gradual upward trend. The Compound Annual Growth Rate (CAGR) over this period is approximately 0.33%, reflecting mild but persistent growth.

Future trends to watch for include:

Climate impacts on water resources, potentially requiring adaptive water management strategies.
Technological advances in water conservation and reuse technologies.
Regulatory changes aimed at sustainable water management.
