This training material is targeted primarily at government officials, with the view that training workshops should be part of a national plan for the support and scale-up of HWTS. These training materials are made up of a Trainer Manual, which provides guidance on planning workshops, selecting trainers and participants, logistic arrangements, and other preparations for workshops. Lesson plans are also provided in the Trainer Manual, with guidance on participatory approaches and the use of the PowerPoint presentations that are included. A Participant Manual (ISBN 9789290616153) with five modules is also available. The training materials may be adapted to suit the audience. As HWTS is relevant for other health initiatives, such as nutrition, maternal and child health, and HIV/AIDS, the wider application and dissemination of this training material is greatly encouraged as an option for improving the safety of water, especially among the vulnerable populations and the poor.
