Appropriateness of Low-cost Sewerage for African Cities: A questionnaire survey of expert opinion

A questionnaire survey was circulated via internet-based sanitation forums to assess the prevailing expert opinion on the appropriateness of low-cost sewerage for African cities. The questionnaire explored opinions about low-cost, solids-free sewerage (settled sewerage), low-cost, solids-transporting sewerage (simplified ed sewerage, condominial sewerage), and conventional solids-transporting sewerage.
