Abstract

:
An urban–rural dichotomy currently exists in policy documentation, accessibility to resources, and human rights. In Brazil, there remains a significant deficit in water and sanitation services coverage, particularly in rural areas. To achieve universal access to water, the legal framework addresses the development of decentralization actions and co-participation in management. As a result, a community-managed water supply (CMWS) has emerged as the social tool in which the community effectively participates in decision-making and oversees the operation and maintenance of water systems. The long-term sustainability of these systems is affected by critical factors in implementation, management, and maintenance. However, no strategic plan exists to solve/mitigate the critical factors commonly associated with CMWS. We proposed an action plan with multiscale intersectoral management strategies to guarantee water security for rural populations. The strategies were separated into areas of responsibility discussed in the recent literature and evaluated by experts. The strategies at the national level were related to institutional aspects and policy formulation. At the local level, the strategies were related to supporting CMWS from project implementation to post-construction. Finally, at the community level, the strategies were related to the quality and financial recognition of the services.

1. Introduction

Water insecurity and injustice almost always respond to the weakened power and lack of visibility that the most remote and peripheral communities have [1]. In Brazil, water and sanitation services (WSS) are structured through public policies with a technical–administrative dimension in the decision-making process, and water supply services are operated by private or public entities. Therefore, it is the responsibility of the state to develop and expand access to water supply [2,3]. Consequently, promoting WSS in areas with low population density, low family income, that are far from urban centers, and that are rural communities is often not considered a priority [4,5,6].
The reality of access to water can be underestimated when analyzed nationally without differentiating between rural and urban areas. Although Brazil still needs to meet the Millennium Development Goals (MDGs) targets on advancing access to water supply, the rural population still faces a significant deficit in WSS coverage [7]. Consequently, the rural population becomes more vulnerable and needs to develop other water sources, such as manual pumping, rainwater harvesting, or healthy water [8].
According to the World Health Organization (WHO), 86% of the Brazilian population can access safe WSS. However, only 40.5% of the population in rural areas have adequate water supply, 33.5% have access to precarious services, and 26% have no services at all [9]. In the context of accessibility to water and sewerage, 1 billion Brazilians do not have access to sanitary facilities; of these, 90% live in rural areas [10]. The conditions expressed by the data clash with the human rights to access water and basic sanitation recognized by the United Nations (UN) since 2010 [11].
In Brazil, basic sanitation is a right provided for by law. According to Law No. 11.445, the public authorities must seek ways to universalize access to sanitary sewage services, drinking water supply, garbage collection, and proper disposal of these residues and rejects. Therefore, all Brazilians must have access to safe, quality, and regular water supply [12]. However, the challenge of WSS management in rural areas remains due to the inexistence or insufficiency of public policies for rural sanitation, the distance from urban centers, and the financial limitations of communities. Without profitability, these areas are not attractive for large service providers, and universal access to water is far from being achieved [7,13].
In this context, the National Rural Sanitation Program (PNSR) highlights guidelines and strategies for action in rural areas, aiming to achieve equity and sustainability in access to water in regions far from urban centers [14]. To this end, the PNSR points out, as one of its strategies, the involvement of the community management of water supply systems (CMWS) in implementing and managing water supply systems.
The CMWS has occurred as a response to government negligence in providing water service to rural areas [15]. According to the authors, it is an important model to meet the objectives defined by the Sustainable Development Goals (SDGs)—“Clean Water and Sanitation” and to achieve universal access to water [16,17,18,19]. The structure of the CMWS is based on the responsibility of the population for the operation, management, and water supply of a local association. Water facilities construction and providing technical, institutional, and political assistance are delegated to external agents [20,21]. However, there is no specific framework for its commencement, since its sustainability depends on adapting to local specificities at an economic, social, and political level. The CMWS is indicated for small water supply systems, especially in communities with 40 to 400 households. This is a central element of investment projects in rural WSS and is already implemented in Brazil and other Latin American countries [14,22,23,24,25].
However, when analyzing the CMWS in the rural communities of several countries, some researchers have indicated the critical factors that influence the sustainability of systems managed by the community in the long term. These factors include the lack of technical and financial capacities, effective empowerment of the community, support after the construction, and interaction between institutional levels [26,27,28,29,30]. Nevertheless, there is a gap in the literature concerning integrated and coordinated strategies and actions to solve/mitigate the critical factors commonly associated with CMWS in several countries [27,31,32,33,34].
In this study, we used a combination of methods based on reviews of the existing literature, lessons learned from successful experiences, and the evaluation of specialists to propose multiscale management strategies helpful in evaluating and planning the management of community-managed water supply systems.

Water Supply in Rural Communities in Brazil

In national territories, water supply services are operated by private, public, or mixed capital entities within the urban areas. These entities, in turn, still need to fully meet the demands of the rural regions [35]. The centralized control, the prevalence of poverty, and the ineffective involvement of public and private entities continue to impede water supply in these areas [36]. Consequently, the absence of these services affects 29.9 million people residing in rural communities [37,38]. In these communities, especially with a greater concentration of poverty, only 40% of the population benefits from a high-quality water supply. In addition, some already implemented water-supply systems are considered deficient, inefficient, or improperly used [9,39].
This lack of technical knowledge hinders the creation of strategic programs that guarantee the sustainability of water supply services. Most government policies apply only to urban areas. Rural communities consequently need more appropriate systems for water supply, sanitary sewage, and solid waste collection. In addition, there exists a high dissemination rate of diseases, such as cholera, leptospirosis, and hepatitis A, which promote a low quality of life, health, and wellbeing in the population [40].
Achieving universal access to water in rural communities is challenging due to the heterogeneity of these areas and diffused occupations. It requires interventions that meet each region’s specificities, as conventional technologies in basic sanitation may become unfeasible. Sustainable management models have been implemented to universalize access to water in these regions [41].
The PNSR represents a group of strategies to develop WSS in rural areas [42]. The objectives of PNSR complement the principles of the National Basic Sanitation Plan (PLANSAB) [12,43]. In 2020, Law No. 14.026 was established to rationalize WSS and increase private sector participation, based on its acknowledgment of the following principles: the right to water, achieving universal access, the eradication of extreme poverty, sustainable local development, promotion of population health, and preservation of the environment. Furthermore, this Law encouraged the privatization of the water supply sector. However, privatization may result in a tariff increase and can further impact gender access to water [44,45].
Additionally, PLANSAB considers it essential to develop a conceptual model addressing the relationship of a technological matrix appropriate to the local reality. It should evaluate the social, economic, cultural, institutional, environmental aspects, community participation, educational actions, and model management. Moreover, the accountability and involvement of government agencies, communities, and NGOs are essential in preparing supply system projects [46].
In the state of Ceará, the Integrated Rural Sanitation System (SISAR) has emerged along with the state policy for water supply and sanitary sewage of Ceará (Law No. 162/2016) [47] as an institutional alternative to provide technical, administrative, and social support for the sanitation utilities installed to serve rural communities. The SISAR is present in 1419 communities and benefits 611,252 inhabitants of rural areas (32% of the rural population) [13]. Currently, eight SISARS act in Ceará, operating in sub-regions geographically delimited by the watershed.
The model proposed by the system receives support from the Companhia de Água e Esgoto do Ceará (CAGECE) and is financed by the World Bank, which also provides administrative and technical support to the system’s operations. While community associations assume the management and operation of the system, SISAR provides training and knowledge transfer to the community, equipment maintenance, and water quality control [48].

2. Materials and Methods

2.1. Critical Factors

This study brings a methodological outline of the research that discusses the critical factors for achieving sustainability of supply systems in rural communities that had the participation of 88 specialists [17]. Therefore, for this research, eleven specialists with experience in water and sewerage management in rural areas were consulted. This is presented with an order of priority in Table 1.
Once the critical factors were identified, alternative strategies were proposed to implement these criteria. To achieve the sustainability of these supply systems, these proposed strategies had the potential to promote this prioritized list of critical factors. They were based on national and international experiences, with evaluated expert assessments.

2.2. The Strategies Plan

The plan aims to systematize information observed in the literature and successful experiences to suggest specific strategies at the national, local, and community levels to address factors that have been identified as critical to the success of the CMWS in ensuring water security for rural populations.
The local term is regional/sub-regional, with the division considering the states’ geopolitical conditions and the grouping of operational factors by geographic, socioeconomic, cultural, and environmental characteristics. This division favors decision-making and applying strategies more consistent with the reality of the communities in question.
The proposed improvement process is illustrated in Figure 1.
The proposed strategies were based on successful experiences in rural communities in the state of Ceará, which are under the management of SISAR, as examples of achieving sustainability in the administration and management of water supply systems. Such proposals are considered within their scope of competence for implementing action at the national, local, and community levels [6].
There were indications for these strategies to achieve universal access to safe and quality water within the rural communities, primarily those with community-managed and operated water-supply systems. Moreover, the strategies were translated into the Brazilian scenario.
Finally, the proposals were presented to specialists operating in rural water and sanitation areas through face-to-face interviews during the VIII National Seminar and III Latin American Rural Water and Sanitation Meeting, held in May 2016 at Fortaleza-Ceará.

2.3. Assessment by Experts

The interviewees were selected according to their interest in participating in this study. Initially, the validation of the preliminary strategies as a solution to the related problems was considered. The specialist panel, with eleven experts in water and sanitation, demonstrated agreement with the actions with either answer ‘yes’ or ‘no’. Based on the first evaluation’s results, the most accepted strategies were selected and improved.
The professionals interviewed had careers in rural water supply and, therefore, had the expertise to judge such proposals. All respondents had at least ten years of professional experience. Among the professionals, five (45%) had between 10 and 15 years of experience in the WSS, and six (55%) had more than 15 years of experience. The distribution by scope of action was also considered. Of the interviewed, three (27%) work in federal institutions, seven (63%) work at the state level, and one (9%) works in the municipal area. The level of education of the specialists was also considered. one of them being a Ph.D. (9%), four with a Master’s (36%), two with a specialization (35%), and four with completed higher education (18%) The survey also gathered the opinions of specialists from different institutions: three (27%) of the interviewees worked in federal institutions, seven (64%) in state institutions, and one (9%) in all areas of activity. The number of specialists interviewed reflects the established parameters of experience and level of education and the history observed in Brazil.
Evaluating the proposals allowed a better adaptation and development of proposals, priorities, and more effective strategies, considering the critical factors and the system’s sustainability in the long term. Only strategies with agreement above 80% among specialists were considered for this study.

3. Results and Discussion

3.1. Strategies at the National Level

The actions determined at the national level are related to the institutional aspects of formulating policies, strategies, and financing. These strategies aim at the institutionalization, legal instrumentalization, and recognition of community organizations. The experts’ assessments of the proposed strategies are presented in Table 2.
Only the proposals that received a positive opinion were considered effective strategies, excluding, therefore, “Define the composition of a national council that acts on issues related to water for human consumption and rural water and sanitation”.
It is possible to observe that the national level is most likely to assume the responsibilities that promote the institutionalization of this management model, favoring an optimistic scenario for developing rural communities and supporting the responsibilities that must be assumed at the local level. The relevance of this level has been reported in other studies. The national administrative and political systems need to support local water supply management systems as a crucial factor in achieving sustainability [15,25].

3.2. Strategies at the Local Level

At the local level, the actions are related to the direct support for rural communities and the strengthening of legal instruments; therefore, strategies must consider the technical, social, and economic variables involved in the implementation and sustainability of services. The assessment of the strategies at the local level is presented in Table 3.
At the local level, all the proposals received mostly positive opinions; therefore, all the proposals were considered effective.
The technology adoption strategy must be influenced by cultural and socioeconomic conditions, considering the principles of acceptability and financial accessibility. In addition, it must consider the environmental and demographic conditions and recognize the local particularities to guarantee access in an equitable and integrative manner [49].
The proposals established that the local level (regional/sub-regional institutions) assumes responsibility for managing the supply, training, administering, and supporting the establishment of tariffs for the self-sustainability of the system. It is the city hall’s responsibility to provide social assistance to support the implementation of the water supply system project, as well as the work execution team, with community participation. To achieve the sustainability of the system, the operating and maintenance costs of the services must be adequate to the population’s ability to pay, with the consequent establishment of a tariff model.
Based on the experience of living in Ceará, SISAR presented the technical, administrative, and social innovations that propose the division of responsibilities within communities and the training and transfer of knowledge to the community, in addition to the use of appropriate management technologies specific to rural areas [48]. In this model, SISAR operates at the subregional level.
The municipality is responsible for the management and planning stages, which must be based on the Municipal Basic Sanitation Policy and the Municipal Basic Sanitation Plan (PMSB), established by Federal Law No. 11.445/2007 as instruments of implementation/jurisdiction [8].
The proposed strategic plan followed the recent literature [16,18,50]. The municipality or state must acquire responsibilities to reduce the urban–rural dichotomy that appears in policy documents. Therefore, this results in making the governance of the resource more effective, establishing more significant political interventions to guarantee equity in water distribution in the communities and outlining co-financing strategies shared by donors, local governments, and community members [15,18,51,52]. It is also up to the state to ensure the effective right to social participation of all social groups, guaranteeing human rights principles and combating social inequalities [53].
Moreover, it is appropriate for the local level to assume responsibility for system maintenance and operation from the planning phase to the support phase. System planning should consider the capacity of the local water resource, incorporate hydrogeological and socioeconomic variables, and understand the economic value that communities attribute to system operation and maintenance services. In addition, adequate technology transfer must be considered to ensure that communities understand the practical options for operation and maintenance [50,54,55,56]. It is essential that, at this stage, the community has its voice heard, and its needs are prioritized. This approach allows for broader community participation to maintain a sustainable supply [57].
After the implementation of the system, there must be post-construction support in the form of a permanent contact channel with the regional or sub-regional institutions, so that communities can routinely contact them to receive assistance, guaranteeing the operations, governance, and financial management of the systems [58].

3.3. Strategies at the Community Level

At the community level, the actions refer to conditions that can be resolved independently, and that would consider the needs and particularities of each community. The experts’ assessments of the strategies at the community level are shown in Table 4.
According to [59], a community organization composed of residents creates conditions for legitimate community decision-making and meeting local needs. While the community association assumes the management and operation of the system, SISAR supports local management by training the operator, a member of the community, in its activities.
In the system operation stage, techniques and methodologies must be incorporated into the rural environment through adaptation to local characteristics and needs. The technical knowledge acquired by community members in their local management and operational activities can also be considered innovation.
Nonetheless, in the proposal of responsibilities and based on the experiences of SISAR, the communities must establish water regulations and keep the community organization regularized. Additionally, they must develop good practices in water use and comply with and enforce the statute and regulations of the rural community. Community organizations are to be encouraged through associations and committees. These organizational structures favor communication with public managers and organizations responsible for technical and financial support, thus managing a more efficient supply system.
The mobilization of financial resources has also been discussed in the literature. The lack of financial resources for organization and maintenance is one of the many problems affecting the long-term functionality of an asset [60]. The community must understand the value of the service and be committed to the purpose of accessing water. Services are negatively affected when there is a lack of persistence on the part of the community regarding the system. Finally, the lack of financial resources for organization and maintenance affects supply functionality in the long term [17,21,61]. However, establishing tariffs must consider the socioeconomic characteristics of the population [25].
Finally, the service quality must be observed. User dissatisfaction with access to resources negatively influences long-term effectiveness. Therefore, a system for the preventive maintenance of reservoirs and the installation of chlorination systems should be proposed, and it should be aimed at maintaining the quality standards of distributed water to protect the consumer [23,62].
A strategic plan to align the critical factors and improve the sustainability of community services is necessary to maintain the functionality of water supply systems in the long term [31,63]. Integrating different factors in the development of a project is essential. In addition, including implementation and process indicators aids understanding the processes by which water points remain functional over time [64].
Therefore, based on these critical factors, a proposal for strategies and actions is presented (Table 5). This was directed among the governmental spheres, indicating their respective responsibilities to provide rural communities with access to quality water and thus achieve sustainability in the management and operation of supply systems.
The political influence in the proposed areas favors the visibility of local communities, allowing them to escape exclusion or peripheralization by positioning them as central actors in the decision-making process. Adopting this plan is believed to provide better local management, foster the empowerment of the population, and articulate and mobilize the community, which can provide new achievements.

4. Conclusions

Community management in rural areas emerged as a solution to the centralized water domain. However, uncoordinated policies, deficiency of technical assistance, and post-construction support negatively influenced access to safe water and the system’s sustainability. The literature indicates that the lack of sustainability in the rural water supply is related to critical factors involving strategies and actions at different levels. This study proposes a multiscale strategy plan to mitigate the critical factors influencing this management model.
At the community level, the strategies focus on system management, the quality of the service provided to the population, the establishment of tariffs for the service, and strategies that should consider the needs and specificities of each community.
At the local level (regional/sub-regional), actions include direct support to communities and legal instrumentalization for the recognition of supply systems, with strategies that include community participation in all the stages of planning and implementation of the system as well as adapting the project to the needs of each community. Sub-regional institutions support a group of communities. Local-level actions are fundamental to community-level strategies. At the national level, actions are related to institutional aspects. The strategies involve formulating a national plan and strengthening local institutions. The actions at the national level are fundamental for the strategies at the local level to be executed.
Notably, due to its continental area, Brazilian rural communities have specific cultural, social, and environmental characteristics in each region. A detailed approach to actions at the regional and sub-regional levels can be carried out in other studies.
To achieve universal access to safe drinking water, all stakeholders must interact with integrated actions at the national, regional, sub-regional, and community levels and in the planning, financing, design, and operation phases involving post-construction support actions.
