The development of sustainability criteria to facilitate the selection of sanitation technologies within the Buffalo City Municipality (Eastern Cape Province, South Africa)

Two and a half billion people mostly in sub-Saharan Africa and southern Asia remain without improved sanitation facilities despite the Millennium Development Goal 7's target to halve this number by 2015. While it might be tempting for developing countries such as South Africa to implement the cheapest and most rapidly constructed sanitation services simply to meet the desired target, this could have significant negative implications on human health and the environment over the long-term. As a result, there is a need to ensure that the most appropriate sustainable sanitation technologies are selected during the planning stage. The purpose of this research was therefore to document the development and pilot application of a flexible context-specific decision-support tool for sustainable sanitation technology selection within Buffalo City Municipality (BCM) in the Eastern Cape Province of South Africa. The first step in the development process was to ascertain the current status of sanitation within the municipality, with a specific focus on the main challenges related to the provision, maintenance and performance of these technologies. Thereafter, a participatory approach was employed involving BCM stakeholders to develop a series of sustainability criteria and indicators that took into consideration economic, social, environmental and technical concerns as well as legal requirements. The development process resulted in a list of 38 BCM sustainable sanitation selection criteria that were applied in a pilot study involving rural, urban and peri-urban communities within BCM. Certain criteria related to topographical features and the availability of piped water and land were considered useful for 'coarse screening' while others were applied during 'fine screening'. In order to enhance the context specificity of criteria, each was weighted, through consultation with key BCM stakeholders. This research confirmed that the sanitation situation in BCM was poor and preliminary evidence indicated that sanitation systems were negatively impacting on the quality of water resources within BCM justifying the need for a sustainable sanitation decision support tool. Based on the pilot application of the BCM Sustainability Selection Criteria List, the urine diversion technology was considered the most sustainable technology option in each study site. There were however, certain social criteria that received relatively low sustainability scores and these would need to be addressed prior to the approval of this technology for implementation. The approach adopted in this thesis was considered highly context-specific yet flexible and appropriate for adoption not only by BCM but other municipalities on a range of spatial scales

Sanitation policy and prevention of environmental contamination in South Africa

Prior to 1994, 21 million people were without access to sanitation in South Africa. Progress towards the backlog elimination started after 1994, but was slow-paced. From 1994 until 2011, the sanitation backlog has been decreased by between 29.8 and 79.2 % from the 1994 levels, depending on the province. Mechanisms were created for implementation of sanitation projects, but this was marginally successful and risk of environmental pollution from sanitation persisted. The period between 2009 and present day seemed to have brought on a significant fast-tracking of sanitation project around South Africa. This coincides with the transfer of oversight and partial implementation responsibility to the Department of Human Settlement and the launch of the Rural Household Infrastructure Programme. It also originated from the integrated programmes which drew in input from all stakeholders at the national and local government levels. Limitations still exist in maintenance and sanitation skills’ portfolio of some local municipalities, mainly in the Eastern Cape and Limpopo Province. However, the present status is still in partial conflict with government aims, legislation and policies. Novel tools such as the Technology Assessment and the Environmental Technology Assessment will have to be implemented in the sanitation decision-making and the novel strategies for skills development will have to be devised. If sufficient maintenance skills are developed in a local municipal area, then this will prevent negative environmental effects and results in lowered sanitation-related environmental contamination. Improvement in can be expected from the new national Department of Water Affairs and Sanitation

Disaster management policy options to address the sanitation challenges in South Africa

The current population of South Africa has been migrating into informal urban settlements that lack adequate sanitation service delivery, caused at least in part by the lack of the necessary skills in the local government sector and the lack of buy in from the community into the provided sanitation facilities. The authors report results of policy research into the relevant disaster management options that could be applied to improve the sanitation service delivery in South Africa. The best policy option was identified as the draft Disaster Management Regulations: Disaster Management. Local government can use these tools through the formation of the volunteer units from the nongovernmental organization sector, the business community, and from among the end users of sanitation facilities. Formation of the volunteer unit should follow the principles of cooperative governance and participatory approach to disaster management. Implementation should be facilitated through the adoption of locally specific municipal by laws

Disaster Risk Management, Ventilated Improved Pit Latrines, and Sanitation Challenges in South Africa

The current paper provides a review and meta-analysis of the practical implications of disaster risk management related to the ventilated improved latrines in South Africa. This technology is evaluated through its legacy and novel challenges of disaster risk reduction. In the current article, the methodology adopted was a literature review and meta-analyses. The results indicate that the in-situ treatment and breakdown of faecal sludge in the ventilated improved pit latrines is not always taking place and that anaerobic digestion might not always be feasible. New strategies are proposed to manage the sanitation-related risks in South Africa by specifying more exact dimensions for the newly built ventilated improved pit latrines by suggesting the use of novel sanitation additives such as fly ash to enhance on-site and in situ treatment, as well as ex situ treatment of the pit latrine faecal sludge. Regular maintenance can lead to prevention of the dysfunctional character of the ventilated improved pit latrines as a functional sanitation technology and a user-friendly hygiene barrier to the spread of sanitation/WASH-related epidemics or infectious diseases. The implementation of the novel strategies should be enhanced by the application of the (Environmental) Technology Assessment in sanitation service delivery in South Africa
