Assessing preferences regarding centralized and decentralized water infrastructure in post-earthquake Leogane, Haiti

Abstract

Though the benefits of centralized water systems (e.g. improved publichealth, environmental protection, streamlined operations, economy of scale, reliability) are well known, these systems are not always feasible or appropriate. In developing world settings there has been growing interest by infrastructure experts,researchers, and international lending institutions in decentralized means of improving access to drinking water. While decentralized water systems with independent components may be less vulnerable to systemic failures, hazards, and extreme environmental events, centralized water systems are often associated with a higher quality of life. This study investigates stakeholder preferences regarding water infrastructure issues in Leogane, Haiti (population ~300,000), a town situated at the epicenter of the January 2010 earthquake.
