Despite significant financial investment, the effective implementation and sustained use of water and sanitation (WATSAN) technologies remains a chimera, with one billion people using unimproved water facilities and two and a half billion not benefitting from adequate sanitation. The poor success rate of WATSAN interventions results from a predominance of supply-driven approaches which lack recipients' inputs into planning and implementation to ensure that technologies are fully absorbed and adapted to users' needs. In the academic literature, users' feedback and experiences of technologies in the post-implementation phase have received scarce attention. The purpose of this study is to investigate users' experience of sanitation technologies in the early post-implementation phase, when opportunities for remedial intervention are still available. Fieldwork comprising semi-structured interviews was undertaken with users and potential recipients of three community ablution blocks (CABs) in informal settlements around Durban. Results suggest that non-technical aspects such as affordability or cleanliness of the facilities can affect acceptance among the investigated communities. User training is positively associated with higher levels of facility maintenance as well as satisfaction with its functionality. A comparison between users and potential recipients of CABs shows that perceived health benefits, attitudes in case of problems, and trust are affected by use of the facilities. Conclusions relate to how early post-implementation assessments of users' experience could enhance the process of acceptance and management of the technology, thereby increasing progress towards achievement of the related Millenium Development Goals.

The most recent UN Joint Monitoring Programme report suggests that achievement of the Millennium Development Goals (MDGs) for water and sanitation remains a chimera, with one billion people still using unimproved water facilities and two and a half billion not benefitting from improved sanitation. Progress on both targets is slowest in Sub-Saharan Africa (WHO and UNICEF, 2008). Recent years have witnessed the launch of several initiatives to alleviate the problem of inadequate water supply and sanitation services, by investing in the transfer of appropriate technologies. However, despite the financial resources and institutional commitment involved, most programmes have failed to deliver the expected benefits (Younger, 2007; Rodgers et al., 2007). Typically, unsuccessful interventions have been characterised by top-down approaches to service delivery with little consideration of recipients' demands or their participation in the planning, construction and implementation process (Breslin, 2004; Burra et al., 2003).
In the post-implementation stage of technology transfer, analyses of poor success rates of water and sanitation (WATSAN) projects focus mainly on the engineering aspects of the process, attributing lack of success to intrinsic technical faults and failings (Lilbken et al., 2007). Alternative diagnoses which address the social and human aspects of technology transfer can be traced back to the work of Linstone (1981) and his conceptualisation of technologies as multi-perspective entities: possessing not only technical aspects, but also a set of organisational and personal dynamics in which the system is embedded. In the context of WATSAN initiatives in developing countries, few contributions have focused on the post-implementation phase of technology transfer, or investigated the reasons why users' desire or willingness to adopt has not translated into appropriately encouraging impacts (e.g. Simms et al., 2005; Mukheli et al., 2002). Findings from these studies attribute project failure to scarce attention to 'software' aspects in the implementation, such as lack of users' participation and capacity building (Burra et al., 2003) or their perceptions of ease and convenience of using the technology (Diallo et al., 2007). Although addressing human aspects of the transferred technology, these contributions provide evaluations of WATSAN technologies which are not guided by strong theoretical foundations and are conducted several months or years after implementation took place (Simms et al., 2005; Mukheli et al., 2002). The consequential lack of a constructive time frame for remedial action makes it difficult to establish accountability and to plan interventions.
In this study we respond to these weaknesses, by exploring and assessing the experience of community ablution block (CAB) users in informal settlements around Durban, where WATSAN provision is due to expand over the coming years to provide services to 317 new settlements. The investigation rests on the perspectives developed by Linstone (1981) as well as on the theoretical framework provided by the work on Receptivity, whereby the success of an implemented technology can be measured by investigating users' willingness and (crucially for this study) their ability to 'absorb, accept and utilise innovation options' (Jeffrey and Seaton, 2004: 281-282). The main premise behind the Receptivity model is the benefits to be gained from understanding the people's responses to a technology, in terms of perceptions, attitudes and agendas for change which are relevant to them. The Receptivity framework allows researchers to explore technology users' perceptions of problems related to water and sanitation and their ability to scan for new knowledge (Awareness); their understanding of the potentiality of knowledge exploitation and its association with needs and capabilities (Association); the process of learning to gain the knowledge and skills necessary to adopt a technology (Acquisition); and their ability of internalising it in their routine, organising maintenance and managing risk (Application).
The importance of Receptivity to the conduct of this research rests on its focus on feedbacks from CAB users by directing attention to those aspects of their experiences that influence acceptance of the facilities and thus their sustained use. The analysis of the research findings identifies potential challenges in technology implementation and suggests solutions, based on users' involvement, which increase a sense of ownership and acceptance of the technology. The timing of this investigation is opportune to provide an agenda for change, as Durban local government is expanding its provision of shared sanitation to the city's informal settlements.
Urban sanitation in South Africa
As a middle-income developing country, South Africa suffers unequal income distribution, with 34% of its population living below the poverty line (UN, 2005). This discrepancy is primarily reflected in the provision of basic services, such as water and sanitation, which are inadequate in informal settlements, characterised by high density of inhabitants, a largely transient population and poor health conditions.
South Africa has committed to meet MDGs Target 10 on increasing improved water and sanitation access by the year 2014. The efforts to expand coverage began after the apartheid era (1948-1994) through a more democratic redistribution of essential services according to principles of equity and dignity (Eales, 2008). With recognition of water scarcity and unequal resource distribution in the country, the Water Services Act of 1997 and National Water Act of 1998 established the right of all citizens to free water and basic sanitation as part of a strategy to fight poverty, whilst the new South African Constitution of 1996 transferred to local governments the responsibility for WATSAN service provision.
Besides reinstating the controversial debate on the nature of water as a public good, the principle of free water and sanitation bears important implications for WATSAN provision. Service delivery is thereby driven by supply-side approaches to achieve high coverage rates, a strategy which is often to the detriment of user engagement (Kihato and Schmidt, 2002). Although demand-driven and community-based approaches to water and sanitation interventions are recognised by South African WATSAN policies (DWAF, 1994), enthusiasm for participation does not often materialise in practice (Friedman, 2006). As reported in previous research on service delivery, users' agendas are not always transferred in consultative processes where feedbacks are inputted into project design (Friedman, 2006). Typically, service providers' mandates for WATSAN provision focus on providing access within tight project deadlines, and inappropriate human and financial resources (Eales, 2010). This approach to tackling service delivery is typical of most municipalities, despite differences in available resources and overall performances.
In Durban, eThekwini Metro is the authority responsible for providing WATSAN services to 3.5 million people. The challenges faced by eThekwini in meeting MDG Target 10 are enormous, ranging from increasing water scarcity and water stress (DWAF, 2004) to an unnervingly rapid urbanisation rate. The worst scenarios faced by eThekwini lie in the urban areas, where an estimated 1 million people of African/Black ethnicity live in densely-populated settlements (1 437 people/km2) under conditions of informal land tenure. Migration to informal settlements is driven by the need to find shelter in the proximity of job opportunities in the city (Marx and Charlton, 2003).
eThekwini's strategy to meet the MDGs entails the transformation of the city's informal settlements, either through relocation of their residents to new houses or on- site upgrading by means of basic services and infrastructures provision. To this purpose, community sanitation systems were chosen as the most appropriate solutions to swiftly serve disadvantaged communities. A CAB comprises a shared sanitation facility connected to a local sewer where the effluent is channelled. The units are characterised by separate areas for male and female users, each one with toilets or urinals, hand washbasins and showers. Provision is usually made for a storeroom and a washstand. Installation costs are incurred by the municipality, whilst users are expected take over management responsibilities. In most areas a caretaker is appointed by users to clean the toilets and liaise with the municipality on maintenance requirements. The caretaker may work on a voluntary basis or receive some compensation through a pay per use scheme.
Our assessment of CABs in Durban is explored by formulating 6 research questions (presented in Table 1), to investigate aspects of users' experience in a context of supply-driven free basic services. The responses to the research questions suggest a novel agenda and new solutions for the implementation of CABs in Durban.
Data generation to respond to these research questions was effected via verbally administered semi-structured interviews. Three CAB schemes were selected on the basis of their operational age. Specifically, the first 2 units (Case Studies A- Clermont and B-Amaoti) had already been in use for 3 years and 1 year, respectively; a third unit (Case study C-Clermont) had just been completed at the time of investigation and recipients had not yet used it. Within the case study area servedby each technology, users were randomly selected throughtransect walks, generating a total of 136 valid responses. Thequestionnaire was specifically developed for this investigationand contained a demographic component (summarised in Table 2), and questions concerning use of the CAB, its maintenance, as well as perceived benefits, challenges and acceptance.
Responses from Case Study A and Case Study B were employed to answer the first 5 research questions. Questionnaire responses were coded and processed using the Statistical Package for the Social Sciences (SPSS) V.17 software. A Chi square test was used to measure the existence of associations between those nominal variables that constitute 5 hypotheses developed from the research questions. Furthermore, to answer the final research question, experiences of use, elicited from Case Studies A and B, were compared with anticipated experiences from Case Study C.
In addition, physical inspections of the facilities were undertaken to check their operational condition. The purpose of these inspections was to validate the results of users' interviews. To obtain an unbiased picture of their condition, CABs were inspected without notifying the attending caretaker.
Three sets of results are presented in the following paragraphs: a descriptive assessment of users' experience with the technology; tests of statistically significant associations to evaluate the hypotheses derived from research questions; a comparison of experienced and anticipated benefits of CAB use.
Results and analysis
Users' experiences of shared sanitation
Users' experiences of the facilities in Case Study A and B are reported in Table 3 (next page).
Inspection of the unit in Case Study A identified broken washing units and pipes. The block was unclean and malodorous and soap was not available to users. A facility caretaker was appointed by the community and worked on a voluntarily basis. The CAB was free to use for the community, with only a small contribution to be paid on a voluntary basis for maintenance. Conversely, the sec ond CAB (Case Study B), was clean and in good working condition. A caretaker was available in loco day and night and a pay per use scheme in place. Each user paid an amount ranging from 0.5 to 1 South African Rand to use the facility.
The aggregated data from Case Studies A and B were employed to test a set of hypotheses generated from the first 5 research questions. Table 4 reports the null hypotheses and the results of the Chi square tests.
Comparison of experienced and anticipated use
The final research question, presented in Table 1, explores how experience of using the technology affects users' perceptions of the system. To this purpose, perceptions from potential users' of a newly installed unit (Case Study C) were investigated. Descriptive statistics are reported in Table 5.
In order to assess the extent to which technology use may have influenced users' perceptions of the systems, results from Case Studies A and B were compared with the findings from Case Study C. Figure 1 illustrates a comparison between anticipated and experienced aspects of CAB use.
A decrease of 24% is reported in the perceptions of health benefits generated by using the shared toilets between Case Study A and Case Study C. This may be dictated by loss of enthusiasm for the systems and motivation to keep the toilets in a good status. A further variation is reported in respondents' anticipated and experienced attitudes in case of problems with the facilities. Whilst 75% of potential CAB users anticipated that they would report problems to the municipality, actual CAB users' willingness to address the municipality significantly decreased with experience of use (25% and 11º%). Finally, recipients' trust in those individuals or institutions which might provide advice on the CAB facility was recorded by asking respondents to indicate whose advice concerning the CAB facility was most trusted. In Case Study A, 45% of respondents indicated that they would trust the eThekwini municipality, with a small majority (55%) found to trust only themselves or their neighbours' opinions about CABs. Results from Case Study B reflect findings from Case Study A, in that a small majority of users (56%) only trusted themselves or their neighbours for advice related to the CABs and only 44% trusted the municipality. In comparison, trust in the municipality among potential users' was slightly higher, (53%), this result being further corroborated by their predicted intentions to inform the municipality in case of problems with the technology. These findings provide some evidence that experience of using CABs may influence perception of the benefits related to the facilities, as well as attitude towards and trust in service providers.
This study highlights some of the factors which facilitate or impede implementation and acceptance of CABs in eThekwini municipal area. Similar to previous post-implementation evaluations, the investigation ascertains the importance of 'nontechnical' aspects as a key influence on the process of WATSAN implementation and acceptance. Statistical results demonstrate that users' acceptance of CABs can be undermined by lack of cleanliness (as in Case Study A), or lack of affordability (as in Case Study B). These findings conform to conclusions from other studies (please reference them again!), as discussed in the introductory section. The majority of users surveyed in Durban were aware of the problems related to CABs and suggested potential improvements to the existing situation. Respondents with experience of CAB use from Case Study A and B suggested an increase in personal safety and privacy, as well as the introduction of regular cleaning and maintenance procedures. Similar findings have been highlighted by other studies (Diallo et al., 2007; Duncker et al., 2006), where convenience of use, cleanliness and privacy emerged as important issues from the investigation of acceptance of household latrines and UD toilets respectively.
Results of the Chi Square tests (Table 4) underline the importance of training in increasing users' awareness of maintenance as well as their satisfaction with the technology. Furthermore, even if, as our findings suggest, pay-per-use schemes positively influence caretaker presence and, consequently, facility cleanliness and tidiness, they do not appear to be correlated with users' satisfaction with the CAB. Although characterised by different payment schemes, neither of the CABs in Case Studies A and B met with significant levels of satisfaction. The affordability of sanitation systems is a controversial issue, particularly within a context of free service provision like South Africa, where WATSAN services are perceived as a symbol of human dignity and a legal right (Eales, 2008). Our results, however, suggest that users' financial contributions to CAB operation would provide an important incentive to caretaker availability, thus enhancing security and cleanliness, both desirable improvements suggested by users. Respondents' participation in training activities represents a further positive influence on user satisfaction with CAB facilities. Training proved to be correlated with respondents' satisfaction with both facilities and with proactive attitudes towards problem solving. This may relate to the role played by users' consultations and engagement in enhancing their responsibility for and acceptance of the service provided. Evidence of this argument is provided by studies on communal sanitation in India, where toilets designed, built and managed by communities attracted a high degree of acceptance from users (Burra et al., 2003).
Our findings on experienced and anticipated aspects of CAB use (Fig. 1) deserve particular attention since they corroborate results of the Chi square test (Table 4). Although Case Study A and B present different scenarios, respondents in both cases exhibit low levels of trust in the municipality's capacity to provide maintenance for the units. Furthermore, a comparison of perceptions of trust shows a discrepancy between the responses from actual and potential CAB users. Where respondents have not yet used the technology, trust in the municipality is higher when compared to that of respondents who were already using a CAB. This discrepancy may be explained by users' disillusionment with technology providers when problems are not adequately addressed. Thus, experience of use may have affected their perceptions of trust and subsequently their indifference towards the systems. This finding is also corroborated by respondents' lack of attention to problems and reporting them to the municipality (Fig. 1). In line with other studies on communal sanitation in Southern Africa (Mukheli et al., 2002), this investigation shows that after a period of use communal facilities may be perceived as mere 'open resources' for which users do not feel accountable. This may relate to the fact that eThekwini's sole responsibility for the provision of sanitation systems constitutes a poor incentive to initiate participatory approaches that would enhance users' sense of ownership.
Conclusions and recommendations
An understanding of non-technical issues is fundamental to the acceptance and sustained use of the implemented technologies. The social, cultural, economic and behavioural aspects influencing technology use should be investigated, not only at the planning stage but also at the early post-implementation phase, when interventions to mitigate problems are still possible. This study shows that low satisfaction levels for CABs represent a challenge to the systems' sustained use, and thus the overall success of the interventions.
Although presenting one of the most dynamic and progressive WATSAN management plans in South Africa, eThekwini's forthcoming WATSAN interventions would require significant efforts to maximise the progress towards MDG Target 10. As discussed in previous studies (Stalker Prokopy, 2005), the outcome of WATSAN projects could be significantly improved through users' involvement in decision-making. Participatory approaches should be promoted from the planning stage of interventions through inclusion of recipients in the decision-making processes. Furthermore, regular training of CAB users should be provided to counter the problem of frequent migrations in informal settlements. Community-based financial contribution plans could be created by linking them to micro-finance activities related to the sanitation facilities, such as locally-managed shops, health centres and recreational spaces. With users' input into project design, CABs could be transformed into central areas of the settlements where social activities occur. In the post-implementation stage, mechanisms for monitoring CAB performance should be in place. Users' motivation and responsibility could be kept high through the use of post-implementation awards for the best performing facility, as successfully implemented in East Asia (Evans and Tremolet, 2010).
