The information from the past three surveys indicates that from a very low level of $0.6 million
invested from 1997 to 2002, a strong investment programme was pursued, investing $16.4 million
between 2002 and 2007. This investment has continued, but at a lower level, investing $11.8 million,
in river and flood control over the 2008 to 2014 period.
As to be expected with the expanded capital involved, the operating
irrigator is rotated manually according to weather conditions and
wastewater availability. Irrigator run lengths are about 400 m, with a wetted width of 45 m, giving an area of
about 1.8 ha per application. An independent automated control system is in place for control of spray drift
towards Wai-inu Beach.
The land that is irrigated is largely undulating stabilised sand dunes, with an overlay of free draining yellow
brown soils of very low natural fertility, that frequently have periods of

rate, effluent flow rate and composition, receiving water quality, odour at the plant boundaries, effluent
loadings and soil and herbage for irrigation areas. The Council undertakes inspections of the plant site and
irrigation areas. Monitoring includes effluent quality checks and inter-laboratory comparisons, water quality,
air quality and biological monitoring.
The Council’s monitoring programmes for the period under review included four inspections, 52 groundwater
and 22 surface
rubbish located within 25 m of the stream, covering the site with 500 mm of clay, which was shaped to the
desired contour, capping with 500 mm of top soil and re-vegetating with grass (Photo 2).

Since the recent closure of the dump, the consent holder has rehabilitated the site. This
has involved removing all rubbish located within 25 m of the stream, covering the site
with 500 mm of clay, which was shaped to the desired contour, capping with 500 mm
of top soil and re-vegetating with grass.
