The aim of this guide is to support contracting authorities, local decision-makers and their partners to develop their sanitation service by providing them with decision-making tools and practical methodological approaches. This guide will help these stakeholders determine whether non-conventional sewerage really is the most appropriate option for the area concerned. If this option is selected, it will also help them coordinate their project effectively and provide them with a clear understanding of the management methods that can be used and of the skills and know-how required.

This guide consists of four parts:

  1. The first part provides a methodology for planning out the area-wide sanitation service and selecting the most suitable types of sanitation. It sets out the advantages and disadvantages of the non-conventional sewerage option compared to other sanitation systems and outlines a number of conditions that need to be met to ensure that this option is properly aligned to local requirements.
  2. The aim of the second part of this guide is to inform the decisions that need to be made when designing the future non-conventional sewerage service, both from a technical perspective and with regard to the division of roles and funding. 
  3. The third part aims to focus attention, and that of contracting authorities and their project supervisors in particular, on key aspects of the service construction phase.
  4. Finally, the fourth part outlines the tools required to successfully manage and monitor the system and thus ensure sustainability of the service.
