: Not applicable.
: The authors of this paper have an obvious conflict of interest, having all been involved in depth with either the original development of the CHC methodology, the intervention on the ground in CBEHPP in Rwanda or through being trustees, managers, volunteers, or founders of Africa AHEAD, the NGO where the CHC Model originated. However, this disadvantage is perhaps balanced by the fact that our experience over 30 years of CHC programming should qualify us to provide an informed analysis of this CHC intervention, as we are strongly committed to ensuring best practice in the WASH sector. Our opinions are those of the Africa AHEAD team and not that of the Government of Rwanda or Academic Institutions or funders associated with this research.
