This guide, developed in partnership between IRC and RAS-HON (Water and Sanitation Network of Honduras), presents guidelines for the planning, design and implementation of MUS systems in Honduras. It has been developed and tested in the context of a pilot MUS programme, consisting of 6 MUS systems in the Department of La Paz. Lessons from these pilot systems have been taken up in these guidelines. The guides consist of a conceptual introduction to MUS in the context of Honduras, a series of steps in planning MUS systems and tools that may help in this process.
