Sustainabilty framework

This document sets out a framework for sustainable water supply and sanitation services and hygiene behaviour change in low-income countries. It is intended primarily to guide WaterAid country programmes, but it is hoped it may stimulate the thinking of other agencies too. Its focus is primarily on rural populations who constitute the majority of those as yet unserved by improved water supply and sanitation services. However, where relevant, references are made to urban practice. It focuses more on water supply than sanitation and hygiene, since the evidence base is stronger in the former than the latter.
