WasserWasserSysteme

WasserWasserSysteme refers to an approach in water management that emphasizes the reuse and circulation of water within a system. The term is used in German-language discussions to denote integrated, closed-loop designs that minimize freshwater intake and reduce discharge.

Key principles include modular design, system integration across supply, treatment, and distribution, and the use of decentralized treatment technologies. Systems often combine rainwater harvesting, graywater recycling, and recycling of process water in industrial contexts, with attention to safety standards and public health.

Common technologies include rainwater collection, filtration and disinfection, graywater treatment (biofilters, membrane processes), blackwater treatment (anaerobic digestion, nutrient recovery), energy recovery, and smart sensors and control systems for monitoring water quality and flow.

Applications span urban buildings, campuses, industrial facilities, and municipal water networks aiming to reduce freshwater demand, increase resilience to drought, and lower lifecycle costs.

Origin and usage: The term emerged in environmental engineering literature in the 2010s as part of broader discussions about water reuse and circular economy. It is used both descriptively and as a brand name by some regional initiatives.
