communicated that two different delivery systems were used during the 2023/24 monitoring year:
1. Dribble bar – main method of effluent application, depths applied (~3mm)

2. ‘Weta’ travelling rain gun – used to apply effluent to the Sand Dune block at 8-10mm depths during
7 months of the year.
Type of crops grown
Two crops were grown under the cut and carry system in 2023/24. Maize Silage paddocks (37.2ha) which
were cultivated in October and

Naturally, it’s more intricate than that.
Down near the mouth, if the tide is coming in and the light’s just right on a fine
autumn morning and there hasn’t been any rain for a day or two, the water is the
deep, dark green of pounamu as it slides past the town.
Upstream at the graceful Bertrand Road swing-bridge, it has the hues of a weak flat
white coffee, and in Tarata country at Pūrangi Bridge, it’s army camouflage.
In the high hill country, north of the “republic” of
monitoring inspection and to take
groundwater samples. It was raining with 8 mm of rain over the past 24 hours.
The newly capped area was starting to grow grass but was still largely uncovered
and quite soft underfoot (waterlogged). The northern batter was inspected and found
to have a minor amount of exposed rubbish where drainage works were undertaken.
This should be attended to once the new cap has stabilised and been grassed over.
There were some areas where there was some minor
Site inspections
17 December 2021 - The camp was quiet at the time of inspection with only one bus, one motorhome and
two caravans in residence. The STDC officer noted that the holding tanks had been full as a result of heavy
rain but had reduced the following day. While there have been odour complaints in the past, at the time of
inspection there were no odours or visual issues near the WWTP or trenches. The sea was a turbid brown at
the time, and there had been lots of rain preceding the
the final aerobic pond into the neighbouring Waiongana Stream in
compliance with the conditions of Consent 0715.

bacteriological sampling at four sites at Urenui and five sites at
Onaero.
The monitoring showed that the wastewater treatment systems at the beach camps did not adversely affect
the water quality of the local freshwater and coastal environments. Although high bacteriological results
were returned from the water quality sampling efforts, these counts were attributed to surface runoff
draining the upstream agricultural catchment, following the rains that preceded the sampling.
There was one
remediation pad. Any rain run-off and leachate that is
generated, drains into a series of ponds for treatment. Between each pond there is a
baffle that skims off any floating hydrocarbons as the leachate passes through. These
ponds also treat the leachate and stormwater from pad 1 where remediated drilling
wastes are stored and/or processed further. The treated liquid from the pond
treatment system (PTS) is then irrigated to cut and carry pasture on two irrigation
areas.
