Proposed extension to the Southern Landfill

With only four years left until the current stage of the Southern Landfill is full, we’ve been busy looking at the best ways to manage our City’s waste.

Latest update March 2020

Here’s a recap of where we’re at:

  • Alternatives have been investigated and the option for the immediate future has been determined – extending the Landfill. 
  • Technical studies to assist with the design are being finalised. 
  • A draft concept design for the extension has been developed.

Background

The Southern Landfill is a critical piece of sanitation infrastructure for Wellington. We accept waste from kerbside collections, commercial collections and materials delivered by residents and businesses to the on-site transfer station.

The Southern Landfill is the only facility in Wellington City that accepts special waste including all the city’s dewatered sewage sludge, contaminated soil and asbestos containing materials. The existing disposal area will likely reach capacity as early as 2023.

Waste generation is projected to rise in line with population and GDP (Gross Domestic Product) growth. The Landfill itself does not generate waste; waste minimisation begins well upstream of the Landfill. Wellington City Council is committed to reducing the amount of material landfilled by 30 per cent by 2026.

We evaluated the waste management alternatives

In November 2019, we evaluated the waste management alternatives to landfill.

Engaging with the community

We’ve been talking to the community about the best way to manage waste for Wellington City in the future, you can find out more at www.letstalk.wellington.govt.nz/southern-landfill-future.

What next?

We are finalising the technical studies to help with the detailed design of the Landfill extension and to support our resource consent application that will be lodged in 2020. We will continue to talk with, and seek feedback from, interested parties prior to finalising the design.

The technical studies include:

  • Air:
    • Odour and dust
    • Landfill gas generation
    • Noise and vibration
  • Water:
    • Aquatic ecology
    • Groundwater (hydrogeology)
  • Land:
    • Geology and geotechnical
    • Contaminated land
    • Terrestrial ecology
    • Landscape
  • Roads:
    • Assess impacts on traffic in and around the site
  • People:
    • Cultural values
    • Archaeology
  • We’ll be showing the final design to the community prior to lodging resource consent applications.
