Refuse, Pond and Channel Designs
Project Highlights
Integrated Sustainability delivered a multi-phase geotechnical and civil design program to support coarse refuse material storage, runoff control, and closure planning. Work included expanding the refuse footprint through staged stockpile lifts, designing a sediment pond system, and evaluating till cover materials to reduce infiltration. Slope stability modelling, geotechnical testing, and material sourcing assessments informed design viability and positioned the site for phased construction and long-term discharge compliance.
Project Deliverables
- Completed slope stability analysis for expanded stockpile heights.
- Confirmed slope, foundation, and toe stability using circular slip surface modelling.
- Outlined conceptual cap designs including single- and dual-layer options with drainage and erosion control.
- Mapped likely clay material zones and developed a follow-up investigation plan for boreholes and lab testing.
- Designed a 132,000 m³ sediment pond with compacted clay liners, armoured inlets, and compliant discharge features.
- Integrated channel routing, berms, and road crossings to support year-round water management and site access.
