Water scarcity is a huge challenge for industrial and urban developments. As such developments are based on a secure water supply, strategies to ensure the required water quantities must be put into effect. In this context, sustainability is becoming an increasingly important factor due to the worsening of pollution and climate change. The integrated industrial–urban water‐reuse concept (IU‐WA‐RE) links gray and green infrastructures by providing reuse water for different infrastructural purposes. Municipal and industrial wastewater is treated separately in different water resource recovery facilities. As a baseline the SEMIZENTRAL approach with the Resource and Recovery Center (RRC) and the Industrial Wastewater Management Concept with a focus on Reuse (IW 2 MC→R) for the industrial wastewater treatment are taken into account. These approaches are new concepts for wastewater treatment “fit for purpose.” IU‐WA‐RE combines the water‐reuse concepts by linking reuse water flows between the urban area and the adjacent industrial park, but focuses not on a production internal water reuse. The concept is designed to offer a holistic strategy to increase the water‐reuse potential and thus the water resources. It offers a solution to cover the lack of water requirements in urban areas. It is therefore possible to drive sustainable urban developments. Practitioner points The water‐reuse potential increases enormously by combining industrial and municipal wastewater flows. Industrial wastewater should be treated “fit for purpose” and applied in the urban area since the municipal wastewater is not sufficient to cover its own water requirements for infrastructural purposes. Water‐reuse for infrastructural purposes increases water resources. The application of reuse water drives sustainable urban developments.
