The construction of the Cell 0 piggyback liner system at Reedy Creek Landfill is being carried out in two stages over a non-operational waste cell. Stage 1 focuses on the eastern section, tying into existing Cells 1 and 2 West Wall, while Stage 2 addresses the western section, divided into Zones A and B. All construction is occurring concurrently with the landfill’s operational and maintenance activities.

Scope of Works:

• Site Preparation and Excavation: Remove unsuitable material, conduct leachate investigations, and manage excavated waste.
• Subgrade Preparation: Prepare the subgrade and maintain its integrity until covered.
• Landfill Gas Venting System: Construct the landfill gas venting system with provisions for future Stage 2 connection and coordinate with operators to protect it during construction.
• Base Layer Construction: Construct the base layer with provisions for future Stage 2 connection and ensure protection until covered.
• Bearing Layer Construction: Build the bearing layer, considering Stage 2 integration, and protect it during construction.
• Bund and Trench Construction: Construct perimeter and internal bunds, anchor trenches, and ensure approval for geosynthetics placement.
• Geosynthetics Installation: Install geosynthetics layers with proper connections and integrity and conduct liner integrity surveys.
• Drainage and Leachate Infrastructure: Construct drainage aggregate layers, install leachate infrastructure, and integrate with existing systems.
• Access Infrastructure: Construct access ramps, culverts, and drains with provisions for future stages, and complete topsoil placement and revegetation.
• Documentation and Compliance: Submit progressive As-Built surveys and reports, ensuring compliance with approvals and specifications.
