includes effluent storage that is sized with account
for historic local rainfall data, but does not specifically take into
account climate change effects on rainfall. Climate change
predictions for Taranaki generally anticipate more drought and
a greater frequency and intensity of storm events. I will use best
practice dairy effluent management, to maintain suitable
effluent storage capacity that will enable deferred effluent
discharge to land until suitable weather and soil conditions. My

2.2.1 Inspections
6 December 2018
Conditions were overcast with light rainfall during the inspection. The camp manager was not present at the
time of the inspection, and the camp appeared to be quiet.
City Care Water was carrying out a routine check of the pump station during the inspection, and reported
that the wastewater system was being inspected weekly. No visual issues were noted, or offensive odours
detected, during the inspection. The insides of the wet
With regard to consents for the discharge to water, the main points
of interest were plant processes with potential or actual discharges to receiving
watercourses. The neighbourhood was surveyed for environmental effects.
1.4.4 Bacteriological sampling
The Council usually undertakes bacteriological sampling in conjunction with the first
post-Christmas inspections in January. This year, sampling was carried out during the
final inspection round due to the rainfall that preceded the
of gravel bedloads.
The mountain and ranges have a strong influence on rainfall by producing orographic type
events which are often associated with frontal systems and depressions moving across the
Tasman Sea. Although the annual totals are quite high, the way in which rainfall is delivered is
more significant. Short duration, high intensity bursts of rain occurring during a storm event are
potentially much more significant in terms of runoff generated and related damage within the
