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 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. This document does not encompass the following aspects:
