Project: Solid waste system  planning and feasibility study  
 Problem: Develop a waste  management plan that provides  at least 20 years of disposal  capacity.
 Solution: BVA conducted a  thorough analysis of the waste  stream and examined several  proposed disposal and transfer  sites. BVA also prepared a  preliminary waste management  plan and landfill design.    

Located on the Atlantic Ocean on the eastern bank of the Demerara River, Georgetown, Guyana, covers approximately 16 square miles. Together with the surrounding communities, the Georgetown area has a combined population of 180,000. In 1999, the greater Georgetown area landfilled approximately 76,500 tons of waste. BVA assisted with the development of an integrated waste management system to provide long-term management through landfilling, incineration, composting, and/or recycling of the municipal solid waste generated by residents, businesses, and industries.

The mayor, city council, and Ministry of Local Government in Georgetown were working closely with a multilateral bank to analyze the existing solid waste system, assess alternative management solutions, and select and implement a waste management plan. BVA was retained to conduct the pre-investment study for the Georgetown Solid Waste Management Program, including solid waste characterization fieldwork and analysis and data collection and field investigation of potentially suitable sites for the development of transfer stations, sanitary landfills, and other waste disposal facilities.

BVA conducted a waste characterization study of the municipal solid waste received at the city's landfill to determine the concentration of various material types (i.e., paper, glass, metals, plastics, other organics, and special wastes), the moisture content of the waste materials, and the heating value of the waste. Later, BVA examined four landfill sites, two transfer station sites, and one incinerator site to verify the suitability of the sites—based on existing data and a field investigation of geologic, geophysical, hydrogeologic, soils, meteorological/atmospheric, and topographic conditions—for future disposal use.

Using the findings of our site assessment study, BVA identified a suitable landfill site and prepared a conceptual site design. Incorporating local geologic features, our design included a composite liner design system that relied on naturally found clay soils and a flexible membrane liner with a leachate collection system.
