In 2023, self water supply to the manufacturing sector in Germany stood at an estimated 3.77 billion cubic meters. Between 2024 and 2028, forecasts project a slight decrease, with values gradually declining from 3.74 billion cubic meters in 2024 to 3.61 billion cubic meters in 2028. The year-on-year variation shows a steady decline, reflecting a diminishing trend in self water supply to the sector. This equates to an average compound annual growth rate (CAGR) of approximately -0.91% over the forecasted period.

Future trends to watch for include:

Potential impacts of environmental regulations that may encourage resource efficiency.
Technological advancements in water conservation and recycling within the manufacturing processes.
Changing economic conditions influencing industrial demand for self-supplied water.
