Kate Valley Landfill, Canterbury, New Zealand

Kate Valley Landfill, Canterbury, New Zealand


Waste Management NZ Ltd



Commissioning of the new Canterbury regional landfill at Kate Valley in June 2005 was the culmination of more than five years investigation, planning, design and construction effort.

The project is a cooperative venture between five territorial authorities including Christchurch City (population 800,000) and Canterbury Waste Services Ltd - a wholly-owned subsidiary of Waste Management NZ Ltd.

The project provides a residual waste disposal solution that integrates with extensive regional recycling and resource recovery initiatives.  The physical isolation of the site provides a low-impact disposal solution, enhanced by an advanced liner system comprising clay and multi-layer GCL/geomembrane and full range of environmental control systems.

The landfill has a footprint of 38.5 ha and will contain 11 million m3 of waste.  We have been involved with the project since its inception - assisting with site selection, obtaining resource consents, completing whole-of-life planning and detailed design of all cell development and infrastructure on the site.
