Detailed Design for a New Sanitary Landfill for the Subic Bay Metropolitan Authority, Olongapo, Philippines

The Subic Bay Metropolitan Authority (SBMA) was created in 1992, after the United States Navy closed down its operations. The former US Naval Base was converted to a freeport zone, utilizing the facilities left by the US Navy. In order to keep up with the demand of a growing enterprise zone, SBMA endeavored to ensure that adequate basic services were maintained, including solid waste management. To that end, SBMA contracted a landfill siting study to determine the most suitable location for a new landfill site. Following identification of a suitable location, the detailed design of a state of the art sanitary landfill was undertaken. While the design project included numerous components, three primary elements are addressed within this report. These elements consist of drainage and hydrology; leachate generation, handling, and treatment; and liner system design and stability.
