No / The human right to water offers a strong legal tool for empowering millions of people living without safe drinking water around the world by creating legal obligations and standards for universal access to safe drinking water. The human right to sanitation creates legal obligations and standards for progressive improvement of access for the bil lions of people living without a basic level of sanitation services and the millions depending on open defecation. Both rights have evolved through closely linked processes at the international level, with implications for water and sanitation governance processes at the national level. This chapter analyses the co-evolution of the human rights to water and sanitation and the legal foundations of the rights at the international level, while highlighting the relationship between the rights and discussing the unique developments which each right has experienced. The chapter also considers the implementation chal- lenges and justiciability issues that will shape the future development of both rights at the international and national levels.

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.

Thesis (M.Dev.) --University of Limpopo, 2008 / Rural sanitation researchers, particularly in the Limpopo Province, have not offered theories in relation to the patterns of the development of rural sanitation. Several researchers have concerned themselves with the need for the solution of water supply but not sanitation services. The present study seeks to enhance the understanding of the dynamics of the patterns of the development of rural sanitation in the Capricorn District Municipality, in particular at the Eisleben Village. This research paper applied an evaluative methodology to assess the impact of VIP sanitation technology at Eisleben Village at Ramokgopa under Capricorn District Municipality in Limpopo Province in comparison to dry sanitation. Supportive cases studies on sanitation delivery in South Africa have also been cited to where both technologies have been applied to assess their impact to the health and dignity of the communities, the environmental impacts. Examples of such case studies included examples of the Mosvold Hospital Sanitation Programme, the Northern Cape Household Sanitation Programme, the eThekwini Water and Sanitation Programme and the Dry sanitation in an urban environment at Weiler’s Farm in Johannesburg. The following five major findings emerged from the study: 1. Sanitation development should be community driven in terms of information, knowledge and decision making. 2. There is need for the vision of health, hygiene and education strategy for water and sanitation. Efficient and effective hygiene education is urgently needed. 3. There is resounding evidence from previous sanitation projects done in various places in South Africa that dry or waterless sanitation has been found to be an adequate sanitation technology that best suits urban, peri-urban and rural areas. 4. There is need to replace VIP with a better technology such as dry sanitation as a matter of urgency to avoid unhygienic and unhealthy conditions due to inadequate VIP sanitation technology. 5. Sanitation solution and technology should comply with the Department of Water Affairs and Forestry (DWAF) policies of adequate sustainable water and adequate sustainable sanitation solution, Millennium Development Goals (MDGs) and the German Helmhotz Association HFG’s “concept of integrated sustainable development”. In the main, the study suggests possible strategies and mechanisms to overcome the challenges that are identified in the research, with the idea in mind of contributing in improving sanitation, not only in the Eisleben Village, but rather to all rural communities in the Limpopo Province, South Africa.

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.
