ISO DIS 30500

Description / Abstract: This International Standard specifies technical requirements, test methods, and sustainability considerations for non-sewered sanitation systems.

A non-sewered sanitation system, for the purposes of this document, is a prefabricated integrated treatment unit, comprising frontend (“toilet facility”) and backed (“treatment facility”) components that

1) 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

2) is not connected to a networked sewer or drainage system.

This document is applicable to sanitation systems that are either manufactured as one package, or, manufactured as a set of pre-fabricated elements designed to be assembled in one location without further fabrication or modification that influences the system function.

NOTE: The plane or surface (e.g., flooring, concrete pad) upon which a fully assembled NSSS is situated is beyond the scope of this standard.

This document also covers non-sewered sanitation systems backend components that are designed to be integrated with one or more specified frontends that meet relevant national and/or international standards.

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

The following information is considered out of scope of this International Standard:

1) Guidelines for selection, installation, operation and maintenance, and management of sanitation systems.

2) Transportation of treated output outside of the sanitation system (e.g. manual transport, transportation by truck or trunk pipes) for further processing, reuse, or disposal;

3) Treatment processes taking place at another location separate from that of the frontend and backend components;

4) Reuse and disposal of sanitation system output; and,

5) Sanitation systems constructed in-situ.
