“…The sustainability of the OSS was assessed by defining a set of sustainability criteria and related indicators. The criteria were selected based on available scientific literature assessing wastewater systems 4,8,10,15,18 and were organized into five main categories: Environmental, Economic, Socio-cultural, Technical and Health-related. A number of assessable indicators were defined for each criterion, which were accounted for either qualitatively or quantitatively ( Table 1).…”

“…Several studies have discussed and proposed indicators based on sustainability principles to evaluate wastewater treatment systems based on literature data. 4,10,11 Furthermore, life cycle approaches, [12][13][14][15] environmental systems analyses 16,17 and sustainability assessments 18,19 have been applied. Due to the large number of small-scale and on-site sanitation technologies that currently exist, 20 and despite the criteria and indicators already suggested in the scientific literature, 8,10,11 there is a lack of application of such information in a knowledge-based decision support context for OSSs that also incorporate the stakeholders' views to handle the trade-offs between indicators.…”

“…When considering various water supply alternatives, the evaluation and optimization of life cycle cost can be invaluable to the decision‐making process (Bradshaw, Ashoori, Osorio, & Luthy, ). A more comprehensive triple bottom line analysis might even be warranted because of its ability to simultaneously consider the social, environmental, and economic implications of an engineering design (Haak, Sundaram, & Pagilla, ; Schimmoller, Kealy, & Foster, ; Schoen et al, ). With respect to social considerations, the recent literature demonstrates that, when designed and operated properly, potable reuse systems provide adequate protection of public health (Amoueyan, Ahmad, Eisenberg, & Gerrity, ; Amoueyan, Ahmad, Eisenberg, Pecson, & Gerrity, ; Chaudhry, Hamilton, Haas, & Nelson, ; Pecson et al, ; Pecson, Trussell, Pisarenko, & Trussell, ; Soller, Eftim, Warren, & Nappier, ).…”

Evaluating the sustainability of indirect potable reuse and direct potable reuse: a southern Nevada case study

et al. 2019

This case study presents a framework for evaluating the sustainability of indirect potable reuse (IPR) and direct potable reuse (DPR) in Las Vegas, Nevada. A system dynamics model was developed to simulate population growth, water supply, water quality, energy costs, net present worth (NPW), and greenhouse gas (GHG) emissions. The model confirmed that DPR could achieve a net reduction in energy costs of up to US$250 million while still ensuring an adequate water supply. However, the high NPW of DPR ($1.0-$4.0 billion) relative to the status quo IPR approach ($0.6 billion) represents a significant economic hurdle, although future monetization of salt loadings and GHGs could reduce that disparity. DPR with ozone-biofiltration would also be hindered by an estimated concentration of total dissolved solids of up to 1,300 mg/L. Despite these barriers to implementation in Las Vegas, certain site-specific conditions may make DPR more attractive in other locations.

“…The deteriorating quality of surface water and groundwater is a global issue, and any measures aimed at improving it must be taken at the stage of local environmental management. Each aquatic ecosystem has a defined tolerance range to progressive human threats and climate change [2]. The latter lead to the depletion of water resources [3] and a deterioration of their quality [4], which intensified the eutrophication process.…”

Matter circulates in nature constantly, between terrestrial and aquatic ecosystems, exchanging elements between the biotope and biocenosis. Each aquatic ecosystem is resistant to a specific load, above which its degradation occurs. It seems that the resistance of cascade reservoirs is higher than that of drainless reservoirs. Changes taking place in one part of the river–lake system cause disturbances in the dynamics of nutrient circulation in another. Rivers supplying water to lakes in a river–lake system have a significant impact on their water quality and on the spatial distribution of pollutants in their bottom sediments and in macrophytes located along their route. The assimilation capabilities of cascading river–lake systems result from their reaction to environmental stressors in the form of anthropogenic factors. They act as natural biogeochemical barriers, limiting the transport of pollutants outside ecosystems. In-depth knowledge of the processes taking place in the river–lake systems enables analyses aimed at forecasting the directions and intensity of these changes and predicting the response of the river–lake systems to the loads from the catchment areas. The collected information makes it possible to create simulations of processes occurring in river–lake systems, which allows for effective action to be taken to protect surface waters. This article provides an overview of available literature, presenting significant research results which enable an understanding of these processes.
