Omarunui Landfill Valley D

Looking at the new stage of the Omarunui Landfill.Planning Started: 2006
Construction Started: 2006
Completed: December 2007

Omarunui Landfill is based at Omarunui Road, off Highway 50. Formerly a farm, the landfill is built among hills southwest of Taradale. It uses the original valleys for most of the infrastructure, with some major excavation work required.

Landfill construction began in 1987 and the site commenced operation in late 1988, initially taking waste just from the Hasting District. Since late 1989, Napier City has also disposed of its waste at Omarunui.

Four valleys are suitable for refuse disposal, with the overall capacity giving the landfill a life of 50 years. The possibility that this could be extended a further 20 years is being investigated.

The first stage in the Valley D, the landfill's final development, is open and expected to last two years. Each of the four stages is likely to have a different lifespan, with a total life expectancy for Valley D of 12 years.

The last stage, timetabled for 2018, will integrate Valleys A and D, effectively allowing for a further four-metre layer of waste to be laid over part of the operation completed in 2006. This will require the reshaping of a ridge.

Without rubbish compaction, the total space in Valley D would equate to 1.75 million cubic metres. Big machinery achieves about 90 percent compaction, however, so the available space is used to its full potential.

A three-liner system will be used in constructing Valley D. That will ensure Omarunui adheres to best international practice and rank it among New Zealand's best landfill operations.
