Benalla Landfill

Construction of Landfill Cell 2 to EPA andBPEM requirements.

Scope

Keystone Civil delivered the construction of Landfill Cell 2 for Benalla Rural City Council, meeting strict EPA and BPEM requirements. The project involved complex, environmentally sensitive works, with precision at every stage.

Surveying and set-out were completed under licensed supervision using GPS technology to ensure accurate earthworks. Dewatering was carefully managed with controlled pumping and agreed discharge locations. A high-quality clay liner was installed using GPS-guided 45-ton excavators and 40-ton dump trucks, with each layer compacted to meet impermeability standards.

Following this, geomembrane and geotextile layers were placed according to approved specifications, with skilled technicians completing welding and rigorous testing to ensure integrity. The leachate collection system was then installed with advanced welding methods such as electrofusion and butt welding, and alignments verified by surveyors. Leachate aggregates were placed with precision, and protective haul roads were constructed to prevent liner damage. Care was taken to level materials and avoid liner movement during placement.

Quality assurance was embedded in all activities, with inspections, documentation, and hold points built into the program to ensure compliance and performance. The result was a technically sound, environmentally compliant landfill cell delivered to the highest standards. Innovative Thinking: Our commitment to sustainability and innovation was evident in the project, where we employed a Telebelt for the placement of leachate aggregate, significantly reducing our carbon footprint and delivering a high satisfactory outcome to the client.

Project Delivery

A series of pumps maintained continuous dewatering to reduce delays, with controlled discharge to an agreed location. A Telebelt was used for leachate aggregate placement, reducing plant movement over sensitive liner areas and supporting efficient delivery.
