Cosgrove Landfill – Cell 3

Construction of two engineered landfill cells at Cosgrove Landfill to support Greater Shepparton City Council's long-term waste management requirements.

Scope

Keystone Civil was engaged by Greater Shepparton City Council to construct two engineered landfill cells, Cell 3A and Cell 3B, within the operational Cosgrove Landfill facility.

The project involved bulk earthworks, subgrade preparation and engineered fill placement, followed by installation of geosynthetic clay liners (GCL), HDPE geomembranes and geocomposite drainage layers. Works also included anchor trench construction and a leachate collection system incorporating sumps, risers, pumps and HDPE pipework.

Working within an active landfill environment, Keystone coordinated construction activities around ongoing site operations while meeting strict environmental and Construction Quality Assurance (CQA) requirements.

Project Delivery

Construction was staged across two separable portions to manage material supply, specialist liner installation and operational requirements. Close coordination with Greater Shepparton City Council, independent quality assurance personnel and specialist contractors supported safe delivery, environmental compliance and quality control throughout the works.
