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.
