“…Greywater is wastewater which contains a large amount of drinking water and which is used for irrigation when the plant is grown enough to be able to consume water containing particulates (Jeong et al, 2018). Unlike short-term methods, reuse of greywater resolves an important part of societies' problems and will remain an indispensable and unchangeable method for the far future (Mara et al, 2001).…”

Lack of water resources, on the one hand and degradation of the quality of available resources; on the other hand, raise serious concerns about water supply. Limited water resources in some areas necessitate planning for use of unconventional resources, such as: Unconventional and recyclable water resources, which should be used optimally. Therefore, there is an increasing need for use of low-quality water in areas where freshwater is scarce, in which case, unconventional water resources (such as saline water, brackish water and household wastewater) can be considered as valuable resources. The aim of this study was to investigate the possibility of water extraction from household wastewater (greywater) and surface water running in villages in Abadan and to simultaneously evaluate some water collection systems to find the best one in order to use these water resources as unconventional and recyclable water resources for various uses such as: Agriculture and irrigation of date palms. In the present study, we investigated three systems for the collection of surface water and household wastewater (greywater) in villages of Abadan The studied systems included: A conventional system, a small-diameter gravity sewer system and a simplified conventional system. We evaluated the said systems using all three methods in five villages of Abadan County as case studies. While estimating the economic cost of implementing each of these systems and taking into account the existing economic, social and cultural constraints, we recommended the most suitable system for the extraction and collection of wastewater and surface water in the region considering the lack of a system for the collecting and disposal of surface water and wastewater. The results indicated that the small-diameter gravity sewer system was more preferable than the other two methods. The studied villages included Albuhameed Manyoohi, Abudgol of Arvandkenar, Hadd of Arvandkenar, Sadat of Bahmanshir and Tarreh Bakhakh.

“…Lastly, several studies performed life cycle assessment of wastewater reclamation as a decentralized approach to urban wastewater management [264][265][266]. They emphasized that local wastewater reclamation is environmentally preferable to the common centralized system, especially for non-potable uses, agricultural and urban, with environmental and economic advantages.…”

Wastewater reuse as a sustainable, reliable and energy recovery concept is a promising approach to alleviate worldwide water scarcity. However, the water reuse market needs to be developed with long-term efforts because only less than 4% of the total wastewater worldwide has been treated for water reuse at present. In addition, the reclaimed water should fulfill the criteria of health safety, appearance, environmental acceptance and economic feasibility based on their local water reuse guidelines. Moreover, municipal wastewater as an alternative water resource for non-potable or potable reuse, has been widely treated by various membrane-based treatment processes for reuse applications. By collecting lab-scale and pilot-scale reuse cases as much as possible, this review aims to provide a comprehensive summary of the membrane-based treatment processes, mainly focused on the hydraulic filtration performance, contaminants removal capacity, reuse purpose, fouling resistance potential, resource recovery and energy consumption. The advances and limitations of different membrane-based processes alone or coupled with other possible processes such as disinfection processes and advanced oxidation processes, are also highlighted. Challenges still facing membrane-based technologies for water reuse applications, including institutional barriers, financial allocation and public perception, are stated as areas in need of further research and development.

“…Operational requirements, such as electricity production, largely affect the environmental impact contributions of water management and heating systems [38,39]. The 2018 Alberta electricity mix was used as the default alongside a 2040 projected electricity mix, and a hypothetical 100% renewable energy mix [40,41].…”

Life Cycle Assessment of Community-Based Sewer Mining: Integrated Heat Recovery and Fit-For-Purpose Water Reuse

Municipal sewage contains significant embedded resources in the form of chemical and thermal energy. Recent developments in sustainable technology have pushed for the integration of resource recovery from household wastewater to achieve net zero energy consumption and carbon-neutral communities. Sewage heat recovery and fit-for-purpose water reuse are options to optimize the resource recovery potential of municipal wastewater. This study presents a comparative life cycle assessment (LCA) focused on global warming potential (GWP), eutrophication potential (EUP), and human health carcinogenic potential (HHCP) of an integrated sewage heat recovery and water reuse system for a hypothetical community of 30,000 people. Conventional space and water heating components generally demonstrated the highest GWP contribution between the different system components evaluated. Sewage-heat-recovery-based district heating offered better environmental performance overall. Lower impact contributions were demonstrated by scenarios with a membrane bioreactor (MBR) and chlorination prior to water reuse applications compared to scenarios that use more traditional water and wastewater treatment technologies and discharge. The LCA findings show that integrating MBR wastewater treatment and water reuse into a district heating schema could provide additional environmental savings at a community scale.
