Abstract:In developing countries, the drinking water supply is still an open issue. In sub-Saharan Africa, only 68% of the population has access to improved sources of drinking water. Moreover, some regions are affected by geogenic contaminants (e.g., fluoride and arsenic) and the lack of access to sanitation facilities and hygiene practices causes high microbiological contamination of drinking water in the supply chain. The Water Safety Plan (WSP) approach introduced by the World Health Organisation (WHO) in 2004 is now under development in several developing countries in order to face up to these issues. The WSP approach was elaborated within two cooperation projects implemented in rural areas of Burkina Faso and Senegal by two Italian NGOs (Non-Governmental Organisations). In order to evaluate its sustainability, a questionnaire based on five different sustainability elements and a cost and time consumption evaluation were carried out and applied in both the case studies. Results demonstrated that the questionnaire can provide a useful and interesting overview regarding the sustainability of the WSP; however, further surveys in the field are recommended for gathering more information. Time and costs related to the WSP elaboration, implementation, and management were demonstrated not to be negligible and above all strongly dependent on water quality and the water supply system complexity.

“…The derived index may be a rational and transparent basis for recommending postconstruction support for a rural water utility. The limitations of the presented research are the comprehensiveness and effectiveness of the data considered, being slightly biased to the accessibility of information, in the absence of a more rational data-recording system (Dwivedi and Bhadauria 2014).…”

'Decision Making is the act of choosing between two or more courses of action'. However, it must always be remembered that there may not always be a 'correct' decision among the available choices. There may have been a better choice that had not been considered, or the right information may not have been available at the time. Multiple-criteria evaluation problems consist of a finite number of alternatives, explicitly known in the beginning of the solution process. In Multiplecriteria design problems (multiple objective mathematical programming problems) the alternatives are not explicitly known. An alternative (solution) can be found by solving a mathematical model. The number of alternatives is either infinite or not countable (when some variables are continuous) or typically very large if countable (when all variables are discrete). But both kind of problems are considered as a subclasses of Multi Criteria Decision Making problems. The MCDM problems can also be divided into two major classes with respect to the way the weights of the alternatives are determined: Compensatory and Outranking Decision Making. The example of the former is Analytical hierarchy Process (AHP) and the latter is ELimination and Choice Expressing Reality (ELECTRE). The basic working principle of any MCDM method is same: Selection of Criteria, Selection of Alternatives, Selection of Aggregation Methods and ultimately Selection of Alternatives based on weights or outranking.Keywords Fuzzy decision making Á Analytical hierarchy process Á Outranking methods Á Decision making in water resources 2.1 Definition MCDM or MCDA are well-known acronyms for multiple-criteria decision-making and multiple-criteria decision analysis. MCDM is concerned with structuring and solving decision and planning problems involving multiple criteria. The purpose is to support decision makers facing such problems. Typically, there does not exist a
“…As explained before, the Multi-Attribute Theory (MAUT) method was selected to interpret the identified attributes and the Analytical Hierarchy Process (AHP) was used to assign weights to the selected attributes. This approach has been used in similar studies in the field [15][16][17]22,57], and is considered useful and adaptable [46]. Table 1 summarizes the attributes and indicators (with codes) identified to assess the sustainability of RWSS with their corresponding weights and data collection methods.…”

“…There are a number of studies that have developed multidimensional assessments of rural water supply systems in developing countries using multi-criteria analysis, specifically the Analytical Hierarchy Process (AHP). In some of these studies, AHP is used to select suitable alternatives for water provision [11,12], whereas others focus on the assessment of water supply services at a country level [13], district level [14], the individual family level [5,15], or the collective water system level [16,17]. Molinos-Senante et al [17] assessed and compared 40 rural water supply systems in Chile.…”

“…However, the assessment was based on expert judgement and secondary information, using only a few indicators to generate recommendations at the country level. Dwivedi and Bhadauria [16] assessed 11 systems in India, but acknowledged the potential bias in the collection of information resulting from data collection instruments focused on easy to collect information that comes from a small sample size. In addition, attributes measuring system performance in rural areas-such as those related to policies, rules and norms, collective action, population characteristics, users acceptability, accountability and transparency, conflicts, risks to service provision, and environmental impact of technology-are typically not included.…”
Rural water supply systems (RWSS) in developing countries typically have deficiencies that threaten their sustainability. This research used Multi-Criteria Analysis and the Analytical Hierarchy Process to identify indicators that can be used to assess the sustainability of RWSS. The assessment tool developed is composed of 17 attributes with 95 quantifiable indicators. The tool enables the assessment of the sustainability of RWSS, using data collected through semi-structured interviews, social cartography, technical inspection, household surveys, and water monitoring. The tool was applied in a case study of a RWSS in the Andean region of Colombia, illustrating a participatory, holistic, and structured assessment that provided a single sustainability measure for the system (3.0/5.0). The tool’s completeness is represented by its extensive attributes and indicators that deliver a robust baseline on the state of a system, help identify improvement strategies, and monitor system performance over time that can assists rural community organizations with RWSS management.
