Non-sewered sanitation technologies allow for access to safe and sustainable sanitation options for the underserved. The international standard ISO 30500 specifies general safety and performance requirements for design and testing as well as sustainabilityconsiderations for non-sewered sanitation systems (NSSS). South Africa is the second country in Africa to adopt this voluntary standard as SANS 30500. The ability to test and certify NSSS against an ISO standard provides regulators with the advantage of relying on global expert opinion and experiences to ensure the safety and performance of these systems for South African citizens. However, testing technologies against SANS 30500 can be expensive and would require significant investment by technology developers to achieve certification for their system. Moreover, the laboratory capacity for testing against SANS 30500 in South Africa does not yet allow for testing easily against the full standard. South Africa also lacks a defined framework on how to achievethe certification in a reasonable timeframe and in a manner that is beneficial to all stakeholders. These factors make it practically very difficult for technology developers in South Africa to achieve ISO 30500 certification. The purpose of this project is to develop a cost-effective mark scheme for the certification of NSSS against SANS 30500, identify in-country laboratories with the capacity to provide testing against the entire standard, and test at least one Class 1 and one Class 2 NSSS under the proposed mark scheme in order to identify any other barriers to NSSS systems achieving certification in South Africa and provide potential solutions going forward.
