South Africa is a water-scarce country (Otieno and Ochieng, 2004; Wassung, 2010). The current sanitation system mostly used in South African urban areas depends on extensive use of water in a form of flush toilets. The housing sector in major cities is continuously growing and this is putting a strain on water services. The government has explored a range of sanitation technologies including waterborne, the Ventilated Improved (VIP) toilet and ecological sanitation (widely known as ecosan) in a form of a urine diversion dry (UDD) toilet. The latter provides a reasonable solution to the current sanitation challenge. This study explores the perceptions of the users of the UDD toilets installed in the medium density mixed housing development of Hull Street in Kimberley. Understanding the users’ socio-cultural perceptions of the UDD toilet will contribute to future policy making, as the information can be used to improve the future roll-out of the technology in order to make it more acceptable. The study was qualitative in nature and used a phenomenological research design. The sample size comprised 16 participants, 13 of whom were residents of the Hull Street housing project and three were employees of the Sol Plaatje Housing Company (SPHC). The sample was selected by a purposive sampling method. Semi-structured interviews were conducted to collect data for the study. The data was analysed by means of content analysis, which enabled the researcher to identify important themes for the study. The findings of the study revealed dissatisfaction regarding the use of the UDD toilet, which emanates from poor design of the toilet facility. The research was successful in identifying, inter alia, odour, uncomfortable sitting position on the toilet mainly by female users and high cost of operating and maintaining the sanitation system. Recommendations emphasise the importance of involving users in future UDD sanitation projects and educating the public at large about sustainability aspects of this sanitation technology (UDD). One of the key lessons drawn from the study is that challenges experienced by the users should be used to improve future UDD toilets.

<p>The purpose of this study was to examine the level and extent of community participation in the Danga Ecological Sanitation Project carried out in the Zvishavane district of Zimbabwe. The people-centered approach was chosen as a theoretical background. Both quantitative and qualitative methods were used to gather relevant information. The results indicated that the community was not fully involved in the ecological sanitation project. As a result, the project had a poor performance record. In the course of this study, political interference in community projects carried out in Zimbabwean rural communities, resulting in the failure to reach the intended beneficiaries, was also noted. Full community participation in community projects may ensure that empowerment and ownership take place.

The widespread practice in Latin America of separating greywater from blackwater at the domestic level lends itself to the application of Ecological Sanitation, or Ecosan. In this research simple, low-cost subsurface flow wetlands, or reedbeds, were investigated not only for their potential in treating the greywater component but also to evaluate their acceptance as an appropriate Ecosan technology in rural Central America. The hypothesis for this thesis is that Ecological Sanitation, namely via reedbeds for the treatment of greywater can improve sanitation in rural Central America. The first aim of this research determined that untreated greywater was having a significant negative impact on the water quality of the local streams of Monteverde in Costa Rica (the site of this research) and that the associated public health risks will continue to increase in line with population growth. Local residents expressed strong dissatisfaction with the current situation and were supportive of any means to improve it. The second aim of this research was to determine if reedbeds designed according to the principles of Ecosan could provide a healthier, affordable and more sustainable sanitation alternative suitable for rural areas. As a result five case study reedbed systems were designed and installed. All these reedbeds made use of locally available materials and incorporated low-maintenance design features, and research with a local plant species determined a robust macrophyte suitable for use in these systems. The ability of low-cost reedbed systems to successfully treat greywater was demonstrated. The Costa Rican guidelines for wastewater reuse were found to be overly restrictive in regards to fecal coliform limits (<1,000cfu/100mL) and may inhibit the wider uptake of reedbed systems if enforced. Despite this the uptake of the reedbed technology was strong and more than ten systems were installed in Costa Rica as a result of this research. An innovative environmental services contract, the first of its kind in Costa Rica, was developed to ensure on going funding for operation and maintenance of a four-household reedbed system. The third aim was to specifically investigate the use of waste plastic (PET) bottle segments as an alternative media in reedbeds to conventional crushed rock, or gravel. Twelve mini-reedbeds, or cells, incorporating PET media and plants as the two variables, were monitored through wet and dry seasons. This experiment demonstrated that reedbeds incorporating PET segments were able to achieve comparable removal of fecal coliform and BOD when compared to conventional media reedbeds, and at a significantly reduced cost. The local plant species Coix lacryma-jobi enhanced the performance of all reedbeds, most notably in the PET-based reedbeds, which was attributed to the considerably greater root biomass achieved in these systems as compared to conventional media systems. This research has demonstrated that reedbeds incorporating simple, low-maintenance design features are able to provide an affordable and appropriate technology for the treatment of greywater in rural Latin America.

Poor sanitation and open defecation is a major concern in many parts of the world. Ecological sanitation is a possible alternative to the global issue by using dry toilet systems that allow for recycling the waste for other uses. The purpose of this thesis is to determine the cultural perception and design implications toward ecological sanitation in developing countries. By surveying the local population in the proposed environments and implementing a corresponding system, the sanitation system has a much higher chance of sustainability and success. In Northern Uganda, the population was surveyed through a questionnaire and a Visual Preference Survey to determine current conditions, immediate needs, cultural preferences, and attitudes toward the design of sanitation types with the main focus on privacy, placement, type and gender-specific facilities. Results demonstrated that the majority of the population was interested in learning more to improve sanitation and reuse waste for agricultural productivity.

2.4 billion people worldwide lack access to basic sanitation solutions, with major health and environmental impact as a result. The recently adopted worldwide Sustainable Development Goals (SDG) aim to reduce this problem and extend the access to basic sanitation. The sanitation systems have to be safe to manage, and resources such as nutrients within the waste be recovered to a great extent, for the system to be worthwhile. For Burkina Faso, a low-income country in West Africa, achieving the SDGs will be a challenge, especially considering the almost 9 million people that lack access to basic sanitation. One way of achieving this is through Ecological Sanitation (EcoSan), an innovation with the goal of protecting human health and enabling reuse of sanitized human excreta as fertilizer. The overall purpose of this study is to provide sanitation practitioners in Burkina Faso with useful information on how to better carry out EcoSan interventions in the future, within the scope of achieving the SDGs.The study aim is to investigate why and to what extent earlier EcoSan latrines have not been used to their full capacity regarding nutrient recovery to local agriculture. The results are mainly based on a household survey conducted on rural Burkinabe households possessing an EcoSan latrine and supplemented with focus group discussions, key informant interviews and measurements on site. To fulfill the study objective, a material flow analysis was performed which showed that nutrient losses of nitrogen, phosphorus and potassium all were likely to exceed 80%, compared to the theoretically calculated values. Additionally, 14 barriers for recovery of nutrients were identified, where the most important ones concern urine collection and storage. Furthermore, results showed that use and reuse practices tended to be higher if initialtraining focused on agricultural aspects rather than hygiene aspects. / 2.4 miljarder människor världen över saknar idag tillgång till grundläggande sanitetslösningar, med stora effekter på människor hälsa och närmiljö som följd. Tillgång till sanitet ska inte bara uppfyllas, enligt de nyligen antagna globala målen för hållbar utveckling (SDG) ska hantering av det mänskliga avfallet ske på ett  säkert sätt samt att näringsresurserna i detta återvinnas. För Burkina Faso beläget i Västafrika och ett av världens fattigaste länder, kommer det bli en stor utmaning att uppnå SDG-målsättningarna, särskilt med tanke på de nästan 9 miljoner invånare som helt saknar tillgång till grundläggande sanitet. Ett sätt att uppnå målsättningarna är genom ekologisk sanitet (EcoSan), ett koncept med målen att skydda människors hälsa samt möjliggöra återanvändning av hygieniserat mänskligt avfall som gödningsmedel i det lokala jordbruket. Det övergripande syftet med denna studie är att ge aktörer inom sanitetssektorn i Burkina Faso användbar information om hur EcoSan-interventioner kan genomföras bättre i framtiden inom ramen för SDG. Det närliggande syftet var att undersöka varför och i vilken utsträckning tidigare EcoSan-latriner inte har använts till sin fulla kapacitet när det gäller näringsåtervinning till det lokala jordbruket. Resultaten baseras huvudsakligen på en enkät på Burkinska hushåll som äger en EcoSan och kompletterades med fokusgruppdiskussioner, intervjuer med nyckelpersoner och mätningar. För att uppfylla syftet med projektet genomfördes en materialflödesanalys för att kvantifiera skillnaden mellan teoretisk och praktisk återföring av näringsämnena kväve, fosfor och kalium till jordbruket. Förlusten av samtliga tre näringsämnen överskred 80%. Dessutom identifierades 14 barriärer för återföringen, där de viktigaste rör insamling och lagring av urin. Hushållens återföringspraxis tenderade att bli högre om den initiala undervisningen var mer inriktad mot jordbruksaspekten än på hygienaspekten.

Magister Administrationis - MAdmin / The generation of large volumes of solid and liquid wastes in urban and periurban areas of Ghana is a big problem for the people and government of Ghana. It contributes to the outbreak of many diseases in the country such as malaria, diarrhoea and typhoid fever. In managing the situation, a new concept called ecological sanitation (ecosan), which focuses on reuse of waste, has been introduced in the country. The objectives of the thesis were to criticise the environmental sanitation policy by analysing its content in relation to policy implementation arrangements, to discuss programmes and projects identified under the policy, to critically examine the implementation of an ecosan project as a way of achieving the goal and objectives by outlining its implementation processes, prospects and challenges, and to make appropriate recommendations. The analysis and discussion of the thesis were based on both primary and secondary data. The primary data, on one hand, were collected on the prospects and challenges that exist in the implementation of ecosan projects from Kumasi metropolis. The secondary data, on the other hand, were from books, journals and websites. From the research analysis, it emerged that the policy allows the implementation of many sanitation projects including ecosan. Secondly, stakeholders see ecosanto be a good approach to reduce waste generation in the country. However, the main challenges that exist in promoting the concept are inadequate financial support, unavailability of implementation guidelines and lack of knowledge about concept details. It is therefore argued that financial support, implementation guidelines and awareness-creation activities should be available in the implementation of ecosan in the metropolis. Government, private organisations, companies and individuals should each contribute their quota in the support and processes. / South Africa

At the end of the Millennium Development Goal (MDG) period in 2015, 2.3 billion people, 31% of the global population, still did not have access to even basic sanitation services. Of these people, 892 million still practice open defecation, and 856 million people use unimproved facilities such as pit latrines without a slab or platform or hanging latrines or bucket latrines (JMP 2017). Sustainable Development Goal (SDG) Target 6.2 now aims to achieve adequate and equitable sanitation and hygiene for all and sets the ambitious target of eradicating open defecation by 2030. While the number of people open defecating was reduced from 1229 million to 892 million between 2000 and 2015, that pace must accelerate to be achieved (JMP, 2017). In Panama, it is estimated that countrywide sanitation coverage is 71%, and rural coverage 54% (WHO/UNICEF, 2013). Even so, in indigenous areas like the Comarca Ngäbe-Buglé, only 25% of the population has adequate access to basic sanitation (ANAM, 2006). This research builds upon the research presented in (Hurtado, 2005, Kaiser, 2006, Mehl, 2008, and Wilbur, 2014). These theses researched double vault urine diverting (DVUD) latrines, or composting latrines, in indigenous communities in the province of Bocas del Toro and the Comarca Ngäbe-Buglé in Panama. Hurtado, Kaiser, and Mehl researched the design, construction, and pathogen destruction capabilities of composting latrines. Wilbur studied how human attitudes and perceptions serve as incentives or barriers to composting latrine use. In this research surveys, interviews, and observations were recorded in 6 indigenous Ngäbe communities in Bocas del Toro and the Comarca Ngäbe-Buglé. The study quantifies usage of ventilated improved pit (VIP) and basic pit latrines in these communities, assesses positive and negative perceptions of composting latrines, and determines perceptions of feces and the reuse of composted human excrement. The results reveal that of n=103 latrines 88.3% were completed and in use, but only 35.2% were properly covered. To promote proper usage of latrines, continued education and trainings need to be carried out in these communities. Respondents were also favorable to the use of composting latrines, with 61.2% of respondents saying they would be interested in building a composting latrine for their households. The main perceived benefit of composting latrines is the compost, and the most identified barrier to use was lack of prior experience. Other main barriers included user disgust and the amount of work it takes to own and operate the latrine. There were more identified incentives (12) than barriers (11) to composting latrine adoption. Respondents also reported they would react more favorably to their neighbor implementing the technology and using compost than their neighbor would react should the respondent do the same thing. These results indicate the importance of pilot projects in communities, allowing people to see the benefits of the technology and how it works before implementing a larger scale project. These projects would also reduce the stigma associated with being a first adopter. Statistical analysis revealed that the demographics of community, sanitation classification, gender, and primary occupation were significantly linked to survey statements used to measure perceptions on composting latrine use and the use of composted human excrement as a fertilizer. Age, gender, and household size were not found to have a statistically significant link to user perceptions on the same survey statements. Logistic regression analysis was then performed using SPSS statistical analysis software (version 24). The results of this research indicate the importance of setting up follow up trainings as many respondents had forgotten how to properly maintain their latrines. It also suggests the setup of pilot projects for composting latrines, as many respondents were favorable to the technology but did not want to try to own and operate a composting latrine without seeing a successful composting latrine first.
