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

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

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
