The SENT Landfill Extension Feasibility Study is composed of four key study workstreams, namely Engineering Feasibility Study, Environmental Impact Assessment, Sustainability Study & Public Consultation.  Each of the workstreams consists of a number of integrated tasks and the workstreams interacted with one another throughout the whole study. At the end of the study, a preferred extension option will be recommended and its feasibility in terms of engineering and environmental considerations will be demonstrated.
