ISO proposal for the creation of a project committee on “Sustainable non-sewered sanitation systems”


A proposal to establish a new ISO project committee on “Sustainable non-sewered sanitation system” has been submitted by ANSI (USA).


According to the World Health Organization (WHO), an estimated 2.5 billion people worldwide have no access to safe, affordable sanitation and an estimated 1 million deaths per year, primary from dysentery-like diarrheal diseases.


Sustainable non-sewered sanitation systems are a practical solution to address sanitation-related death and disease. The sustainable non-sewered sanitation systems are based on the idea to create reinvented toilets, or “next-generation” toilets that work without a sewer or water connection or electricity and ideally cost less than 5 cents per user per day.


In support of the project “Reinvent the Toilet” initiated by “Bill and Melinda Gates Foundation” ANSI submits a proposal for the creation of a project committee to develop an international standard in the field of sustainable non-sewered sanitation systems. The standard will define criteria to qualify sanitation systems in terms of safety, functionality, reliability, maintainability and usability and that the discharge (treated effluent) is compliant with leading practices. The aim of the standard is to ensure safety aspects related to the operation of the sanitation systems in the intended areas of use and that the treated discharge products pose no user, operator health or environment risks.


The development of another standardization document (IWA) in this field is currently in progress. Once developed, the IWA may serve as the basis for a new international standard developed by the proposed ISO project committee.


In case of national interest, BDS can approve the creation of ISO/TC on “Sustainable non-sewered sanitation systems”. If the establishment of ISO/TC is accepted by the national standards bodies – members of ISO, Bulgaria can obtain P- or O-membership in the work of the newly established committee.


The national stakeholders can provide their position on the proposal for this new field of ISO technical activity by 15 of April 2016 to Violeta Mihaylova, email:, tel: +359 2 81 74 595.
