T and T Landfills Limited operate a construction and demolition landfill in the Owhiro Stream catchment. The site holds a suite of resource consents to operate from Wellington Regional Council and Wellington City Council. The site is located at 289 Happy Valley Road.

In addition to T and T, two other landfills operate in the catchment, the Wellington City Council Municipal 'Southern Landfill' and another construction and demolition landfill known as C and D Landfill.


Latest News - September 2020

In June 2020 GWRC received notifications from the public of earthworks on a ridgeline within T&T landfill and the discharge of contaminants from T&T Landfill into Owhiro Stream. In response to these notifications GWRC have visited Owhiro Stream and have undertaken and a compliance assessment of the site. The Director of T&T Landfill and their agent assisted GWRC with this assessment.

GWRC have identified a number of non-compliances with the Resource Consents for T&T Landfill. GWRC have requested that T&T Landfill undertake a number of actions to address these non-compliances by 30 September 2020.

After 30 September 2020 GWRC will re-assess compliance and make a decision on how to proceed with any outstanding issues - this may include enforcement actions.

We will continue to meet with T&T and inspect the site and Owhiro Stream to inform our investigation.

We will update this webpage as and when we have further information for public release.
