Project History
Timeline for the development and promotion of ISO 30500
In 2011, the need to develop “next-generation” toilets to deliver sanitation to the 2.5 billion people worldwide without access to safe, affordable sanitation and the need for standards in support of United Nations Sustainable Development Goal #6 (SDG 6) was recognized.
In response to the global sanitation crisis, the Reinvent the Toilet Challenge was initiated. The challenge aims to provide access to adequate and equitable sanitation and hygiene for all and end open defecation, while also paying special attention to the needs of women and girls and those in vulnerable situations.
Based on the fact that no ISO Technical Committee existed to address sustainable non-sewered sanitation systems, ANSI together with the Reinvent the Toilet Challenge took the first step by developing an international workshop agreement (IWA). Since there were no reference documents for the new technologies, an IWA was proposed as the most efficient starting point for the development of non-sewered sanitation system standards. The IWA served as the basis for the development of a new international standard through an ISO project committee. The goal of the IWA was to achieve an international standard, which contains commonly accepted criteria by which to measure the performance of reinvented toilets.
In 2016, ANSI submitted proposals to ISO focused on sustainable non-sewered sanitation systems, also known as "next-generation toilets," a practical solution for the sanitation-related death and disease that is rampant among developing nation populations. The proposals were part of a multi-phased initiative to facilitate the development of a globally recognized consensus standard for safer, cleaner reinvented toilets. In October 2018, ISO 30500, Non-sewered sanitation systems – Prefabricated integrated treatment units – General safety and performance requirements for design and testing was published. ANSI is actively involved in promoting the national adoption and use of ISO 30500 and other ISO non-sewered sanitation standards in South Asia, Africa, and China.
ANSI’s partners for 2019-2021 standardization outreach to support national adoption included: African Organisation for Standardisation (ARSO), L'Association Sénégalaise de Normalisation (ASN), Bangladesh Standards & Testing Institution (BSTI), Bhutan Standards Bureau, BRAC, CAP-Net UNDP, Department of Public Health Engineering (Bangladesh), Economic Community of West African States (ECOWAS), Environment & Public Health Organization (Nepal), Nepal Bureau of Standards & Metrology (NBSM), South African Bureau of Standards (SABS), South Asian Regional Standards Organization (SARSO), Sri Lanka Standards Institution (SLSI), Standardization Administration of the P.R.C. (China), Tanzania Bureau of Standards (TBS), The Shanghai Environmental Sanitation Engineering Design Institute (China), TUV SUD (Singapore), University of Kwazulu-Natal (UKZN), Water Research Commission (South Africa). Please note that this is not an exhaustive list.
2020-Present
- ANSI participates in international water and sanitation conferences (like World Water Forum, AfWASA Congress, and IWA Development Congress) to showcase the importance of ISO 30500 standard adoption
- Interviews with sanitation industry experts involved in the development of ISO 30500, implementation of ISO 30500-compliant technologies, and the advancement of non-sewered sanitation solutions published
- July 2025: ISO 30500:2025 published
- First ISO 30500-compliant toilet achieves certification
- June 2023: ISO PC 305 began ISO 30500 revision process
- ANSI continues to develop and update communication materials for the promotion of ISO non-sewered sanitation standards

2018-2019
- ANSI and partners hosted stakeholder workshops on ISO 30500, including national events in South Africa (with SABS), India, China (with SAC and the Shanghai Environmental Sanitation Engineering Design Institute), and a regional workshops in Senegal, Ivory Coast, Tanzania, and Kenya (with ARSO and ECOWAS)
- ISO 30500 published in October 2018
- ISO Final Draft International Standard 30500 finalized, with participation & input from 48 countries. ISO member countries given the opportunity to vote on the final draft
- ANSI participates in the Reinvented Toilet Expo in Beijing, China where the first ISO 30500-compliant porotypes are shown
- ANSI began advocacy work to promote national recognition of what becomes ISO 30500
2016-2017
- Testing of prototypes began in South Africa with the University of KwaZulu-Natal in September 2017
- PC 305 met regularly to draft the international standard using a formalized, consensus-based process
- Project committee (PC) 305 was formed with input from experts across the globe
- ANSI approached the International Organization for Standards (ISO) about beginning the process to create an international standard for sustainable non-sewered sanitation systems-ISO 30500
2011
- Reinvent the Toilet Challenge initiated and grants issued to 16 researchers around the world using innovative approaches for safe & sustainable management of human waste.
