Educational guides

This book is intended not only for development planners and project leaders seeking to disseminate decentralized wastewater treatment systems, but also for engineers who need a tool for designing treatment plants and for everyone who needs to understand the issues involved in wastewater treatment.
It helps to understand the systems and how they can be implemented, as well as serving as a decision-making tool.
