The Mangrove Pond Landfill in Barbados, was nearing capacity and the island had no alternative landfills to receive solid waste. In an effort to ease this critical situation the Government decided to expand the Mangrove Pond Landfill.
Burnside worked with the Sanitation Service Authority (SSA) to design Phase IV of the Mangrove Pond Landfill site. The pre-selected existing quarry site presented several challenges to incorporate a leachate containment system due to the severe grades of the quarry walls. The HDPE and GCL composite liner system anchored to the quarry walls was combined with an engineered clay and sand wedge side wall liner system to overcome these vertical challenges. Burnside was also asked to ensure that the final design incorporate current best practices for environmental protection. Burnside’s final design included a leachate containment and collection system, and surface water management.
Upon completion and implementation the short-term solid waste crisis in Barbados will have been mitigated for up to 8-years. As a result the Government of Barbados can continue to use the Mangrove Pond Landfill whilst further developing the facility as part of the National Waste Management program.
With additional waste processing systems coming online in the future, the lifespan of the Mangrove Pond Landfill could be significantly extended in excess of 50 years. It was integral to the design that health and safety standards were maintained at the Mangrove Pond Landfill and that the underground water supply was protected through an effective leachate collection system.
Engineering projects of all shapes and sizes.
