ISO/SANS 30500 Is Official

17 May 2019

With this Gazette publication, South Africa has become the first nation in the world to adopt the ISO 30500-2018 closedloop water/sanitation treatment standard for facility infrastructure, in the form of the SANS 30500-2019 standard. Also published is the SANS 33003:2019 standard for digital process assessment. Keep pushing forward...



ISO 30500:2018 Non-sewered sanitation systems -- Prefabricated integrated treatment units -- General safety and performance requirements for design and testing

This document specifies general safety and performance requirements for design and testing as well as sustainability considerations for non-sewered sanitation systems (NSSS). A NSSS, for the purposes of this document, is a prefabricated integrated treatment unit, comprising frontend (toilet facility) and backend (treatment facility) components that:

a) collects, conveys, and fully treats the specific input within the system, to allow for safe reuse or disposal of the generated solid, liquid, and gaseous output, and

b) is not connected to a networked sewer or networked drainage systems.

This document is applicable to sanitation systems that are either manufactured as one package, or manufactured as a set of prefabricated elements designed to be assembled in one location without further fabrication or modification that influences the system function. The plane or surface (e.g. flooring, concrete pad) upon which a fully assembled NSSS is situated is beyond the scope of this document. This document is not applicable to sanitation systems constructed in situ.

This document also covers NSSS backend components that are designed to be integrated with one or more specified frontends.

Although this document is primarily applicable to the development of sanitation systems that are not connected to water and electricity networks, it can also be applied to systems that can utilize water mains and/or electricity.

This document defines the basic treatable input as primarily human excreta and gives options for extending the range of input substances. Requirements for the quality of the outputs from the sanitation system are given for solid and liquid discharges as well as odour, air, and noise emissions.

It contains criteria for the safety, functionality, usability, reliability, and maintainability of the system, as well as its compatibility with environmental protection goals.


ISO/IEC 33003:2015 sets out the requirements for process measurement frameworks for use in process assessment. The requirements defined in ISO/IEC 33003:2015 form a structure which

a) establish the requirements for process measurement frameworks in the context of process assessment,

b) establish the requirements for the validation of process measurement frameworks for use in process assessment, and

c) establish requirements that are applicable to any process measurement frameworks to develop composite measures across domains.

ISO/IEC 33003:2015 is applicable to the development of process measurement frameworks for any process quality characteristic across all application domains.
