Patea Beach is an elevated site which for most of the time is dry. Rain that does fall on
the site drains away at a very rapid rate. The site does not suffer from flooding from
rain or tidal action, due to its elevation. Monitoring over the past three years noted no
discharge of leachate or liquids from the base of the dune as a result of the discharge.
Therefore, no water quality samples were programmed or collected at the site

The rain stayed away from Taranaki Maunga in December with just 60% of the long-term average recorded at North Egmont. It was a different story in the Eastern Hill Country with 194% at Mangaehu at Bridge. Across the region, rainfall was 109% of the long-term average. Total rainfall for 2022 ranged from 112% (Kotare at OSullivans) to 158% (Kapoaiaia at Lighthouse) with an average of 128.6% of normal. Mean river flows for December were close to typical December averages at around +19.6% while
from neighbours.
It is acknowledged that other site-specific
considerations will also have to apply, such as:
1. the avoidance of conflict between air discharge
points and neighbouring dwellings
2. land contours
3. orientation to the sun.
(f) Discharge point design
Dispersion of discharges is enhanced by:-
increasing the height of discharge points;
avoiding the use of conical rain shields over
discharge stacks;
October was a month of contrasts for rainfall in Taranaki, ranging from 65% of the average for the month at Waitotara at Hawken Rd to 164% at Mangati at SH3. The average across the region was 101.1% of the long-term average although there was less rain on the Maunga where rainfall was only around 60% at North Egmont and Kahui Hut. Year to date rainfall is sitting between 110% (Kotare at OSullivans) and 163% (Kapoaiaia at Lighthouse) with an average of 126.8% of normal. Mean river flows for

level of control. The technicians use weather forecasting to predict the lime dose,
for example reducing the lime does set point if heavy rain is forecast. However,
the weather forecasts have not always eventuated which sometimes results in
quadrants being under-dosed. The technicians continue to focus on pH control
to achieve target dose ranges.
