Nutzwasserlagerung
Nutzwasserlagerung is the German term for the storage and management of water that is intended for reuse in industrial, agricultural, or municipal processes rather than for direct discharge into the environment. The practice is an integral part of water conservation strategies, aiming to reduce the demand for fresh water, lower wastewater treatment costs, and minimize environmental impacts.
In industrial settings, Nutzwasserlagerung involves collecting process water—often called greywater—after it has been used in cooling
Agricultural reuse, particularly in irrigation, benefits from Nutzwasserlagerung by allowing nutrient-rich process water to be stored
Regulatory frameworks in Germany and the European Union encourage Nutzwasserlagerung through incentives such as the Water
