Neighborhood-Scale Urban Water Reclamation with Integrated Resource Recovery for Establishing Nexus City in Munich, Germany: Pipe Dream or Reality?

With the rapid expansion of cities due to population growth and urbanization, conventional centralized wastewater collection treatment systems are slowly becoming a burden; expensive maintenance is required for aging plants piping infrastructure, cost expanding capacity cover demand from growth, new regulations tighter control over certain pollutants such as micropollutants. As an alternative this system, study discusses feasibility decentralized at neighborhood scale. Taking Water-Energy-Food (WEF) Nexus approach, can support water energy conservation, recovery water, energy, nutrients well generation wastewater, be customized individual requirements, eliminate need lengthy pipe networks. The method employed in comparing economic status quo proposed solution. finds that costs implementing hypothetical reclamation with integrated resource system using anaerobic membrane bioreactor (AnMBR) downtown high-density city Munich, Germany, theoretically recuperated within two years. This may 60% what it run system. By linking AnMBR biogas digestor systematically harvested organic waste co-substrate, generate enough itself even feed some grid. highly hypothetical, yet generating evidence systemic socio-technical transition towards more circular economy optimal recovery.
