Reinvented Toilet Standard National Recognition

2017 - 2021 • American National Standards Institute (ANSI)


To support the recognition of an international standard that will facilitate widespread deployment of low-cost, safe, and effective toilets


The American National Standards Institute supports the Bill & Melinda Gates Foundation’s commitment to solving the global sanitation crisis and is currently supporting efforts to develop an international performance standard for the reinvented toilet in the International Organization for Standardization (ISO). As secretariat of ISO project committee 305, the committee tasked with developing the standard, ANSI has begun and conducted significant outreach to experts and stakeholders throughout Africa, South and Southeast Asia, and other affected countries. Once the standard (ISO 30500) is published in 2018, the next step to advance the deployment of related technologies will be to encourage the standard’s recognition and acceptance at the national level. In addition, other existing non-sewered sanitation international standards would be beneficial to existing and future fecal sludge management (FSM) services.

This initiative to conduct outreach and training with selected target countries in Africa and Asia, with the goal of encouraging countries to recognize the future ISO 30500 and existing ISO 24521 through a variety of possible mechanisms, including national adoption, policy references, and others. The activities will primarily focus on South Africa, India, and China.

Countries of activity

Location of main activity


Goals: Encourage countries to recognize the future ISO 30500 and existing ISO 24521 through a variety of possible mechanisms, including national adoption, policy references, and others. While national recognition will be encouraged broadly, a particular focus on South Africa, India, and China, will direct the grant funds to the largest markets of affected users.

Objectives: This grant will be used to promote and facilitate the recognition of an ISO international standard(s) that will facilitate widespread deployment of low-cost, safe, and effective toilets and safely managed fecal sludge management in areas of need worldwide in order to achieve access to adequate and equitable sanitation for all and end open defecation

Further information

Research or implementation partners: ANSI will work with organizations in each market of focus to carry out project activities. These partners will be identified through initial fact-finding missions and workshops.

Results are not available yet, but will be published here:

Grant size: $ 4.5 million in November 2017
