An Interdisciplinary Approach to the Sustainability of a Gravity-Fed Water System in the Peruvian Andes

Abstract

This paper analyzes the methods used by the Princeton University Chapter of Engineers Without Borders to ensure the sustainability of a gravity-fed potable water system in rural northwestern Peru. While similar small scale development projects consider sustainability in their design process, some do not recognize the importance of an interdisciplinary approach to sustainability. This team, however, is inherently interdisciplinary in nature due to its unique subteam structure, which subsequently affects its approach to sustainability. By examining the technical, social, and financial considerations of the project conducted by the Princeton University Chapter of Engineers Without Borders, this paper argues for a three-pronged approach to sustainability. As can be seen through thoughtful design parameters, strong local partnerships, and strategic financial mechanisms, the project displays promise of future success with regards to sustainability. The main objective of the Princeton Chapter of Engineers Without Borders in this partnership is to ensure that the community has the knowledge, tools, and resources necessary to maintain the water system in a self-sufficient manner at the completion of the chapter's involvement.Since its establishment in 2004, the Princeton University Chapter of Engineers Without Borders (EWB-Princeton) has partnered with communities in several developing countries to implement projects designed to improve the quality of life for their residents. Previous EWB-Princeton projects in Peru have involved installing latrines, solar lighting systems, cookstoves, and most recently, clean water distribution systems.The Peru Team of EWB-Princeton is composed of approximately thirty students of various academic disciplines who design the system, organize logistics, and raise funds during the academic year. The team is organized into four subteams, each of which is tasked with a specific aspect of the project.
