Infrastructure Impact and Sustainability: The Case of Public Sanitation Facility in Indonesia

Abstract

Recently, the focus of infrastructure has been not only on its physical output per se but also on its impact on sustainability. This study aims to introduce an infrastructure framework based on Epstein and Buhovac’s model to better understand the step-by-step process of the creation of infrastructure sustainability for wastewater treatment facility in Indonesia. The study employs a qualitative approach using a qualitative data set from interviews, observations and a survey. We focused on the case study analysis of a wastewater treatment facility in Yogyakarta Province, Indonesia. Through this framework, stakeholders’ participation was found to play an important role, thus enabling the sustainability of the infrastructure project in the future. This active participation is the result of a set of impacts-social, economic, and environmental-that have been created by the wastewater treatment facility in their community. We provide a theory-of-change diagram to explain this process.
