Where can I dump soil in New Zealand?
Vac-U-Digga's Soil Transfer System
The processes that surround discarding the soil or debris left over from construction, excavation, or demolition project can be confusing and costly. Today, we look at places where you can legally dump soil as well as a variety of solutions to help you cut projects costs and reutilise project waste.
In New Zealand you can dump soil at a number of dedicated fill sites across the country. There are strict rules though as to where certain types of soil can be dumped. For example, clean fill soil (such as clay, gravel, rock and soil from areas that are not contaminated with chemicals) needs to be disposed of at a designated clean fill site, while material with low-grade contamination needs to be disposed of at a managed fill site, and lastly, heavily contaminated material needs to be disposed of at designated landfill sites.
Disposal of contaminated material is strictly regulated in New Zealand, where it can only be disposed of at licensed sites. You can also reuse clean soil and clean fill depending on its makeup. Reuse includes using clean fill as fill for holes or excavated sites that need to be filled in.
Soil reuse is a fairly new practice in New Zealand. Both large and small construction projects tend to have excess soil or material and debris like concrete, brick, soil and lumber left over at the project's completion and often end up dumping this excess into landfill sites. Instead of discarding this excess, soil reuse sees excavated material and construction debris repurposed to be used again on another project, essentially recycling soil and waste while reducing projects costs.
Clean fill is waste material, typically collected from construction projects, that can be used in future projects. To be classified as clean fill, the waste material has to contain (in isolation or in combination) dirt, cement, concrete, gravel, brick, topsoil, sand, and rubble. The great thing about clean fill is that you can reuse it to fill things like potholes, decrepit pools, old wells, trenches, and general excavated holes. Cleanfill is particularly useful in non-destructive digging and utility maintenance operations where companies are able to cut costs by reusing previously excavated soil to bury utilities that have been exposed for maintenance.
