This document was developed in the context of the Household Centered Environmental Sanitation (HCES) planning approach shown in Figure 1. The HCES approach is a 10-step multi-sector and multi-actor participatory planning process.
Target User of the Compendium
This Compendium is intended to be used by engineers, planners and other professionals who are familiar with sanitation technologies and processes. It is not a training manual or stand-alone resource for people with no experience in sanitation planning.
The user of this document must have an interest in learning more about alternative or novel technologies which may not be part of the common suite employed or taught in the local context. The approach and information presented herein is meant to broaden the spectrum of innovative and appropriate technologies considered for sanitation planning.
Objective of the Compendium
The objective the Compendium is threefold:
- Expose the Compendium user to a broad range of sanitation systems and innovative technologies;
- Help the Compendium user understand and work with the system concept, i.e. the process of building a complete system, by iteratively choosing and linking appropriate technologies;
- Describe and fairly present the technology-specific advantages and disadvantages.
Structure of the Compendium
The Compendium is divided into 2 Parts; (1) the System Templates and a description about how to use them; and (2) the Technology Information Sheets.
It is recommended that the Compendium user reviews Part 1: Sanitation Systems to become familiar with the terminology and structure of the System Templates and their components. The user can then familiarize themselves with the technologies of interest in Part 2: Technology Information Sheets. The user can move between the System Templates and the Technology Information Sheets (they are cross-referenced) until he/she has identified some systems and/or technologies that could be appropriate for further investigation. Eventually, the user should be able to develop one, or several system configurations that can be presented to the community. The Compendium can then be used, following the community’s suggestions, to re-evaluate and redesign the system accordingly.
The first four steps of the HCES planning approach define the project-specific social, cultural, economic, health and environmental priorities which will influence technology selection and the system design. The goal of steps five (5) and six (6) is to identify specific technological options and to evaluate feasible service combinations. The following steps, seven (7) through ten (10), lead to the formulation or design of a comprehensive Urban Environmental Sanitation Services (UESS) plan. This Compendium is designed to serve as a resource tool during steps 5 and 6 of the HCES planning approach. It is presupposed that the user of this Compendium has a well-developed awareness of the context and priorities of the community and other stakeholders as the social-cultural elements of sanitation planning are not explicitly addressed in this document.
