is 10 L/s. However as a result of stormwater inputs to the pond, the discharge
rate from the pond to the Mangorei Stream will be highly variable as it is dependent on weather conditions.
The size of the pond will allow storage for a 10% annual exceedance event (AEP) event. The maximum
discharge rate from the pond during large rainfall events is 1,060 L/s as this is dictated by the size of the

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

effluent storage capacity that will enable deferred effluent
discharge to land until suitable weather and soil conditions. My

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
