included 24 inspections, 343 water samples collected for physico-chemical analysis, and four
bio-monitoring surveys of receiving waters. In addition, continuous monitoring of the
temperature of cooling water discharged and of the Inaha Stream was undertaken, and a staff
gauge rating was maintained for measurement of flow in the stream.
There was a fire at the inedibles plant on 12 January 2014, which affected the operation of the
plant and the monitoring undertaken for about 12 weeks.
The
review can be summarised by the following main points:
Surface soils across the site are dominated by semi-porous silty clay-loams, overlying more
impervious clay soils
Soils below 2000 mm have not been characterised
Chloride concentrations in the soil beneath the irrigation zone are highly elevated compared
to non-irrigated areas
The shallow groundwater table is in direct connection with semi-porous loamy silty-clay
Due to high rates of irrigation loading, shallow

Strong financial position
The Council finished the 2016/2017 year with a surplus of
$1.6 million (total comprehensive income). Expenditure was

Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by the Trust, this report
also assigns a rating as to their environmental and administrative performance during the period under
review.

to minimise the generation of wastewater, but this could be further improved.
The discharge of wastewater into the Kahouri Stream did not cause any recorded impact on
the macroinvertebrate communities of this stream, and the impact on water quality was
minimal. However, discharge rates to the Kahouri Stream need to be reduced to ensure a 1:100
dilution. The irrigation of wastewater was undertaken with no significant adverse effects on
the environment, but further improvement regarding

18. Mr Chapman stated that TBP has recently made improvements to the irrigation
system including an upgrade to a three pump system and the replacement of timers
on the irrigators to ensure more careful management of the discharge. It was also
explained that frequent sampling of treated wastewater is undertaken by TBP and
measured at an independent water testing facility in order to
