“…Only 11 articles articulated requirements about the quality of an indicator, for example, stating that each indicator needed to be SMART (e.g., specific, measurable, achievable, relevant, and time bound) . While most of those articles did not use the SMART terminology, they had similar requirements of representative or relevant, ,,,− conceptually sound or scientific, , understandable or transparent, , clear and unambiguous, ,,, quantifiable, ,,,, and measurable based on data availability. ,, Whether an indicator meets a specific set of requirements, though, can be context specific (i.e., the same indicator could be SMART in one context but not in another). , Since so few articles discussed requirements for indicator quality, the associated metrics and applications of each article’s listed indicators were reviewed.…”

Despite the existence of numerous sanitation assessment frameworks, it remains unclear how to provide and measure sustainable access to sanitation. A systematic literature review was conducted to evaluate and collate sanitation criteria (i.e., indicators) for evaluating the sustainability or resilience of sanitation systems. The identified indicators represented 30 evaluation themes that included triple bottom line sustainability and technical and resilience considerations, but none of the individual articles had included all themes. In particular, resilience themes were not commonly integrated with other themes. Further, many indicators were not measurable, even though most literature articles (85%) applied their indicators; over a third of the identified indicators had vague or absent metrics. These findings highlight several future research needs, such as developing validation processes to help ensure a set of indicators is sufficiently measuring progress toward or away from sanitation sustainability; expanding guidance on, and options for, data collection and analysis procedures, especially for resilience; and supporting future indicator selection processes, for which a database of existing sanitation criteria was created. These all provide opportunities for improving the measurement of environmental and human well-being associated with sanitation access.

“…It is visible that cost of ecological effect was selected as the most important indicator in economic analysis, due to a very low possible profitability of organized sanitation in rural catchments and low founds available, not only in conditions of the eastern Poland (Peter and Nkambule 2012;Chinyama et al 2012;Engin and Demir 2006;Frone and Frone 2015;Massoud et al 2009;Bouabid and Louis 2015;Widomski et al 2017Widomski et al , 2012Suchorab et al 2015;Chmielewska et al 2013). Similarly, possible odors emission, as the most popular and onerous side effect of sanitary sewerage management was chosen as the most important indicator in environmental analysis, due to the advanced and up-to-date technology of sewage transport and treatment applied.…”

Financial, environmental and social sustainability of rural sanitary wastewater system: case study

et al. 2022

Undeveloped sanitary wastewater systems and sanitation often based on septic tanks of unproven tightness, especially in the eastern part of Poland, pose the significant threat to the natural environment and public health. On the other hand, designing the sanitation systems for rural settlements with low population density, limited volume of wastewater, large distances and variable topography may be a difficult task because the proposed design, corresponding to actual law and standards, should not only limit anthropopressure on the environment but also should gain the local population acceptance due to investment as well as operation and maintenance costs. Thus, in our opinion, the variant analysis concerning financial, environmental and social sustainability of proposed sanitary systems is required at the initial stage of the design process. This paper presents variant analysis of financial, environmental and social sustainability of three variants of sanitary wastewater system proposed for the selected rural located in eastern part of Poland. The studied variants covered: vacuum sewage system, pressure sewage system and gravity sewage system combined with the individual, on-site devices for wastewater treatment. The financial analysis was based on three popular indicators of investment cost efficiency: Dynamic Generation Cost (DGC), Net Present Value (NPV) and Benefit–Cost Rate (BCR), while environmental analysis focused on possible intensity and pathways of emissions. Possible employment as well as social involvement and acceptance were selected as indicators for the determination of social sustainability. Then, the obtained results of partial analyses were introduced to weighed sum model (WSM) allowing to determine the most suitable design, attractive for investors as well as for the local population.

“…The analysis of the financial aspects of the proposed designs, including their costefficiency and economic profitability, was based on a selected set of popular, sound and clear indicators. The cost-efficiency of possible investments was assessed according to the determined vales of the Dynamic Generation Cost (DGC) indicator, which allows us to present the price of ecological effect [107][108][109]. The DGC is a very popular and easy to understand indicator, which allows an assessment of the averaged costs of the product unit during the assumed life cycle of the design, and which was successfully adopted in numerous technical analyses, including not only into various water, wastewater and rainwater systems but also into providing heat energy and materials (fuels plastics, zeolites, etc.)…”

Sustainable rainwater management may counteract the effects of climate change and significantly improve the distorted water balance in urbanized catchments. However, despite the hydrologic advantages of rainwater management, acceptance and willingness-to-pay in the local society are required. This paper presents an assessment of the financial aspects, i.e., the cost-efficiency and economic feasibility, of various designs of rainwater management for a small-scale urban housing community in Lublin, Poland. The research was performed for a housing community covering approx. 1.38 ha and five multi-family residential buildings. The proposed designs covered rainwater harvesting systems, supported with extensive green roofs, with rainwater retained in underground or above-ground reservoirs, used with variable demand for watering the green areas and for underground parking lot flushing. For each designed variant, the investment as well as operation and maintenance costs were estimated. The assessment of the cost-efficiency and profitability of the proposed rainwater management systems was based on three indicators: Dynamic Generation Costs, Payback Period and Benefits–Costs Ratio. The performed calculations showed that only two designs, utilizing above-ground rainwater reservoirs, could be assessed as economically profitable. Thus, local communities may be unable to financially sustain investments in sustainable rainwater management, so it seems that financial support is required.
