Perception management of non-sewered sanitation systems towards scheduled faecal sludge emptying behaviour change intervention

Abstract

AbstractThis paper explores the influence of perception on behaviours associated with emptying of faecal sludge from non-sewered sanitation systems using findings from a study on the emptying behaviour of residents of Khulna city, Bangladesh. The purpose of the study was to highlight perception as a behaviour determinants as well as develop perception management strategies for the design, plan and implementation of effective behaviour change intervention programmes with a focus on ‘scheduled emptying’. The study uses a mixed-method cross-sectional approach to collect data through structured household questionnaire surveys, face-to-face key informant interviews, group interviews, and structured observations. The study revealed that the emptying behaviour of the community was reactive, untimely and unsafe and over half of the systems had never been emptied, which was traced to emptying perceptions that encouraged a laissez-faire attitude within households and the community. The study concluded by proposing a perception management model to achieve behaviour change towards scheduled emptying via perception change.
