wasserfreundliche

Wasserfreundliche describes measures, products or designs that handle water resources responsibly. The term is widely used in environmental and sustainability discussions and is not a legally binding standard; the concrete criteria vary by sector, region, or project goal. At its core, it emphasizes efficient water use, protection of water quality, and avoidance of negative impacts on waterways and aquatic ecosystems.

Applications span architecture and urban planning, landscape architecture, building technology, and consumer products. Typical principles include reducing water consumption, using collected rainwater or greywater, promoting infiltration and permeation rather than surface sealing, protecting water quality by limiting pollutants, and employing water-saving technologies or nature-based solutions such as vegetation and water-retentive soils.

Practical examples include water-efficient sanitary systems, rainwater harvesting for irrigation, green roofs or façades that store and gradually release water, and plant concepts suited for low irrigation needs. In many cases, the term serves as a guiding orientation for sustainability goals rather than a uniform certification; certification schemes and criteria differ by country and sector, so the exact requirements are not universal.

Overall, wasserfreundliche approaches are increasingly relevant in climate adaptation and urban resilience, helping to reduce flood risk, conserve potable water, and protect freshwater ecosystems while supporting functional and aesthetically appealing environments.
