The Council currently charges $267 per tonne for contaminated soil and $350 for asbestos disposal. Silverstream charges $510 for contaminated soil and $398 for asbestos.

Our preferred option proposes incremental year-on-year increases to these fees – over the next three years to limit the impact on the city’s current budgeted construction projects – while bringing our contaminated waste fees into alignment with the region.

Options for consideration

A: Increase the Contaminated Soil and Special Waste (Asbestos) fee incrementally over the next three years (preferred): this will generate about $1.3 million in increased revenue for the Council in 2026/27.

B: Increase the Contaminated Soil and Special Waste (Asbestos) fees by 5 per cent: this will generate about $220,000 in increased revenue for the Council in 2026/27. Note this means contaminated soil disposal will cost less than the cost proposed for commercial waste.

C: Keep the Contaminated Soil and Special Waste (Asbestos) fees to inflation increases only: This will generate about $110,000 in increased revenue for the Council, to cover the inflation increases in costs. Note this means contaminated soil disposal will cost less than the cost proposed for commercial waste.
