“…Several other GW treatment studies using innovative technologies like dual-mode biofilters [25], vegetated vermifilters [26], horizontal flow wetland integrated in a cascading vertical set-up [27], and green walls [28,29] with high removal efficiencies have been carried out very recently. One very promising approach in this regard is the decentralization of urban water management by using NBS such as green roofs and CWs [30,31].…”

“…Wetland roofs (WR) are multi-functional green roofs in combination with a water storage mat serving as a CW, where different marsh plant species (helophytes) are grown on the entire surface of a roof [31][32][33]. They are specially designed as a shallow horizontal subsurface flow CW without conventional substrate on a roof, thus saving weight and additional costs and helping to limit problems like nuisance odors and infectious diseases [34].…”

To solve the upcoming environmental problems, sponge city concepts as well as new technologies are being developed these days. One of the future challenges is to reduce drinking water demand by using decentralized water recycling systems. This study aimed to investigate the performance of a specially designed pilot wetland roof (PWR) treating domestic greywater (GW) at ground level under outdoor conditions and to evaluate the effects of different hydraulic loading rates (HLRs) for a period of two years. The results showed highly efficient removal of typical greywater pollutants from the system, e.g., five-day biochemical oxygen demand (BOD5) > 96%, chemical oxygen demand (COD) > 93%, total suspended solids (TSS) >94%, anionic surfactants (AS) > 94%, ammonium-nitrogen (NH4-N) > 84%, total nitrogen (TN) > 71%, total phosphorous (TP) > 87%, and E. coli (1.86 ± 1.54 log-removal). The mean concentrations of the targeted parameters at the outflow were in compliance with the requirements for discharge to the environment and met reclaimed water quality standards for agricultural irrigation, except for E. coli. Statistically significant (p < 0.05) results of pollutant mass removal rate across different HLRs indicated the potential effect of HLR on treatment performance, and HLR in a range of 67–80 L m–2 d–1 contributed to a higher removal efficiency without compromising the limit values. A comparatively low HLR of 45 L m–2 d–1 should be applicable if pathogen removal is the most important requirement. Plant species showed good plant vitality and adapted well to the water storage mat. The higher the mean ambient air temperature, the greater runoff reduction (>50%) was observed due to high evapotranspiration. The results showed the system is a promising green technology for GW recycling and can be scaled up for application to urban buildings.

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 (IW2MC→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.
