Factors influencing the performance of faecal sludge management services: case study in Thailand municipalities

Abstract

In most low- and middle-income countries, the service coverage of faecal sludge management is very limited resulting in uncontrolled disposal that directly impacts to water resources and public health. Similar to other countries, Thailand is facing faecal sludge management problems which lead to serious challenge to its local government authorities who are responsible for services provision. Local factors may strongly affect faecal sludge management services. Because of this problem, the management measures should be formulated in responding to significant factors affecting the performance of FSM services. This study aimed to evaluate existing faecal sludge management services in Thailand, their strengths, and weaknesses, and identify the significant factors influencing the performance of services. Based on data collected from 160 municipalities in Thailand, factors influencing the faecal sludge management services were identified using multiple regression analysis. The indicators involving operational efficiency, service performance, and treatment feasibility were used for the assessment of faecal sludge management performance. Significant factors encompassing technical, financial, social, and institutional aspects were identified based on each indicator. The findings identified the significant factors and proposed effective measures for improving faecal sludge management services such as providing technical assistance, implementing awareness programmes for private operators and households, and subsidizing investment and operation costs of faecal sludge management facilities.
