Types of fill sites
We currently monitor 30 consented cleanfill sites and six 'Managed Fill Sites' throughout the Auckland Region, which accept low-level contaminated waste.
There are three different types of fill sites:
- Cleanfill – for natural materials such as clay, gravel, rock and soil from areas that are not contaminated with chemicals (this can include small amounts of construction material)
- Managed fill – designed for material with low-grade contamination
- Landfill sites – for heavily contaminated materials and all refuse-type material, such as household and kerbside waste, commercial and building waste, and certain types of hazardous waste (for example, asbestos-containing material).
Disposal of contaminated material is tightly regulated and can only happen on licensed sites. Resource consent is required for these landfill sites, usually with stringent conditions, and all sites have a council monitoring scheme in place.
Managing a landfill site
The operator or consent holder of the filling site must have management practices and robust documentation to demonstrate that all fill brought to the site meets the requirements of the consent.
Fill site operators are required to provide evidence, generally through an annual or six monthly report to us, to confirm:
- which materials are being brought to the site, and that
- fill processes are done in accordance with consent conditions. This includes having fill samples tested at an independent laboratory. Any discharges from the site (such as surface water and ground water) are also tested to determine any risk(s) to the environment.
In some cases after a landfill is full, we can design and implement strategies to remediate and rehabilitate closed landfills for use as active or passive recreational open spaces and wildlife refuges.
List of consented operating landfill sites
The list of consented landfills is updated quarterly and includes clean-fill and managed-fill sites.
