“…the efficiency of greywater recycling is inherently linked to the amount of water consumption. Existing data reveals that tourists generally have a higher per capita water consumption than that of residents [16]. This disparity is particularly pronounced within hotels.…”

“…Secondly, the energy consumption associated with greywater recycling is significantly influenced by the nature of the treated greywater. In tourist resorts, the composition of greywater primarily stems from showers, laundry facilities, and recreational water activities [16]. Notably, these sources yield greywater that is less challenging to treat in comparison to the kitchen water prevalent in typical residential settings.…”

Freshwater scarcity combined with high water demand from rapid urbanization, population growth, and changing consumption has resulted in increasing stress on urban water supply systems. Seasonal fluctuations in the population of tourist destinations are especially evident in tourist resorts. Greywater recycling and rainwater harvesting have been proposed as the most widely used valuable strategies to address water scarcity. By taking the conventional water supply system and the water supply of tourist resorts as examples, this study systematically compares and analyzes the advantages and limitations of greywater recycling and rainwater harvesting by enumerating the stress of water supply in different systems, discussing the benefits of both strategies and comparing the differences when using them for tourist destinations. The results showed that pumping systems or elevated tanks used to meet the water supply needs of high-rise buildings pose energy challenges. The water use characteristics of tourist resorts cause it to be closely related to the seasonal influx of tourists. Greywater recycling is more effective than rainwater harvesting in mitigating tourist resorts' water shortage problem. Suggestions for ways to implement these strategies for different regions are also given to make informed decisions about water distribution efforts. This study provides a reference for sustainable urban water resource management.

“…Based on the Open Coding transcription, the Environmental Service gave an exciting discourse: managing waste in the city of Padang requires a large budget, especially if it is accompanied by the main tasks and functions of managing river cleanliness. The concept of decentralization is helpful for efficient waste management by combining economic efficiency with the environment [15]. In addition, decentralization is needed to encourage lower-level governments (local governments) to compete and show the best performance in management, and granting authority to lower-level governments (local governments) also reduces investment from the Government in economic and environmental development [16] [17].…”

River damage is often caused by human activities, one of which is massive domestic waste pollution in river flows. Using the Good Environmental Governance model, this study analyzes domestic waste management in Batang Arau, Padang City. This type of qualitative research with data analysis techniques Manual Data Analysis Procedure (MDAP). The results show that the domestic waste management of the Batang Arau City of Padang has not yet implemented the Good Environmental Governance model. Field data illustrates several pillars of Good Environmental Governance, such as low community participation, access to information on domestic waste management is not available, and Transparency and Accountability of domestic waste management in Batang Arau are constrained due to the difficulty of collecting domestic community data. Waste. Domestic waste processing in Padang City has not been decentralized and is still centralized. Environmental management institutions in Padang City have not been well integrated because there are still sectoral egos between institutions. The obstacle to managing Batang Arau domestic waste is that the Wastewater Treatment Plant in the city of Padang has not appropriately been facilitated in the city of Padang.

“…In both cases, it was shown that, given specific boundary conditions, the existing centralized treatment options can be successfully integrated into transitional approaches to resource-oriented sanitation, or even completely replaced. When considering the decentralized scenario (membrane technology for the anaerobic digestion of the BW instead of the centralized greywater treatment), Estévez et al [23] found a better environmental performance in terms of resource recovery and a 2 kWh•m −3 lower energy demand required for the operation, based on a sensitivity analysis. Even so, these kind of on-site recovery facilities must be seriously optimized in terms of global warming potential for the operation phase.…”

“…These examples highlight the need for LCA studies that should incorporate the environmental impacts of wastewater treatment systems that are suitable for transitional states and energetic benefits, or consider hybrid wastewater treatment options, as seen in Resende et al [24]. It has been noted that, in addition to the scale, technology, operation, and products that determine the competition between centralized and decentralized systems, another important factor is the system boundaries considered in the LCA [23]. Given this, there are several challenges that will lead to further developments that must consider new data bases, new correlations for energy use at different scales, and the integration of LCA studies into environmental policy issues.…”

Life Cycle Assessment of Black and Greywater Treatment Solutions for Remote and Sensitive Areas

et al. 2023

Sensitive and remote areas have come under pressure from growing populations and tourism, often resulting in improper wastewater management. Efficiency, durability, the use of renewable construction materials, and the minimization of environmental impacts must be conformed to a sustainable paradigm. A life cycle assessment (LCA) was applied to compare three different decentralized wastewater treatment systems built at tourist facilities: a source separation sanitation system with a hybrid constructed wetland (S1), a sequential batch reactor (SBR) with a hybrid constructed wetland (S2), and a solar-powered composting toilet (S3). Benchmarking showed that S1 was preferred over S2. The differences were up to a factor of two, except for eutrophication, which was significantly higher for S2 (10×). S3 had the lowest environmental impact, but S3 treated only the blackwater fraction, i.e., urine, faeces, and toilet paper, and excluded greywater treatment, i.e., handwashing and/or kitchen wastewater. The scenario analysis showed that the environmental performance could be improved by installing solar panels, but this would increase the impact on the abiotic depletion of elements by 83% for S2. The LCA indicated the advantages, disadvantages, flexibility, and potential for design improvements to meet the environmental sustainability and market demands for system diversity.
