This Compendium defines sanitation as a multi-step process in which human excreta and wastewater are managed from the point of generation to the point of use or ultimate disposal. A Sanitation System is a context-specific series of technologies and services for the management of these wastes (or resources), i.e. for their collection, containment, transport, transformation, utilisation or disposal. A sanitation system is comprised of [8185-Products] (wastes) which travel through [8186-Functional Groups] which contain [8187-Technologies] which can be selected according to the context. By selecting a [8187-Technologies]for each [8185-Products]from each applicable [8186-Functional Groups], one can design a logical [8188-Sanitation Systems].
A sanitation system also includes the management, operation and maintenance (O&M) required to ensure that the system functions safely and sustainably. A [8188-Sanitation Systems] defines a suite of compatible technology combinations from which a system can be designed. In Part 1 of this Compendium nine different sanitation system templates are described. A detailed explanation how system templates function and how they are used is given in the section “[8181-Using the System Templates]”.
