The gross environmental condition of the Payatas Disposal Facility in Metro Manila, Philippines, implores the need for sustainable technologies to control and abate toxic municipal solid waste leachate and protect public health. A team of environmental engineers recognized this need by selecting the site as a design project for the Mondialogo Worldwide Engineering Award, sponsored by the United Nations and Daimler Chrysler. The project culminated in a technical proposal that highlighted the following design features: an impermeable dumpsite cap to control leachate generation; vertical impermeable barriers for containment and isolation of leachate; a drainage system to divert clean, surface water from the cap and prevent its contamination prior to discharge; a leachate recirculation system to enhance stabilisation of the waste deposit; and a facultative lagoon and constructed wetland system to treat excess leachate. The oral presentation will present the key leachate control and treatment components of the design as well as data from the phytoremediation experiments conducted to assess the potential for use of a constructed wetland system on site.
