Nitrogen enters the Irrigation Area through the irrigated liquid, rainfall and clover fixation.
Nitrogen leaves the Irrigation Area by being leached below the root zone, by volatilisation and denitrification to
the atmosphere and in the harvested pasture in the form of baleage.
Nitrogen moves between the organic and inorganic pools within the soil. Generally, nitrogen in

rainfall, and one relating to a potable water leak). All of these incidents were deemed compliant with
consent conditions upon further investigation. There were also 19 wastewater incidents that occurred
throughout the wider wastewater network; 12 of which were related to high rainfall that occurred in
November and December in 2020. One incident occurred when a contractor left a pipe plug in the sewer

early November 2009 with three of the sampling surveys performed prior to January
2010. The majority of the surveys were performed over the latter half of the summer
period. Bathing water samples were normally taken between the hours of 0900 and
1800 hours (NZDST) with none collected within a three day period following
significant river fresh conditions. [NB: regional differences in rainfall patterns have
caused difficulties at various sites in the past as localised rainfall may

Altitude and rainfall
In most cases there is a direct
link between rainfall figures and
altitude. Below are some
figures for both.

involved flow metering at key locations in the network to identify
catchments with high I&I, and installation of fibre optic cables throughout 2,681 m of pipes in the
catchment with the biggest reaction to rainfall, to monitor the temperature differences before, during, and
after rainfall events. A report was produced that included recommendations to support a targeted I&I
remediation plan and deliver reductions in I&I, which NPDC will implement moving forward. This
investigation was completed to
Council’s hydrological monitoring team, as the weather conditions meant the demand for
irrigation was high, with irrigation starting as early as the middle of October.
The Council carried out compliance monitoring inspections at 68 sites during the 2015-2016
irrigation season. The inspections included visual checks of the intake structures, screens, staff
gauges, fencing around the pump sheds, downloading of data and stream gaugings.
For the summer irrigation period, the rainfall recorded at
increasing, and measures of water quality are trending in the right
direction. The region is not facing an unmanaged crisis in water quality, quite the opposite situation
is evident.

short, narrow, incised, cool, and fast flowing, and water leaving the Egmont National Park has usually
reached the sea within 24 hours. High rainfall on the mountain generally means that most ring plain

2.3 Mr B Pope, Compliance Manager, in response to the question regarding Clark Peters
Farms Limited, advised that every dairy effluent discharge application is assessed on a
case by case basis and there are a number of environmental factors that are looked at
including land area, land size, and rainfall in the area.
