14 July 2020
A winter Inspection was carried out during fine weather following a period of heavy rain throughout the
catchment. The influent screen was operating and wastes were fully contained. The main pond was
green/brown in colour with a slightly turbid appearance. Odour was noted as being ‘slightly noticeable’. In
excess of 250 Mallard ducks were present on the pond.
Both wetland pond levels were slightly high. These were green/brown in colour and slightly
despite the dry conditions and quite strong wind. There were no odours noted onsite. The truck
wash had recently been used and all washings were captured. The sand trap was cloudy in appearance, the
level was lower than the drain and this was not discharging. In general the site was tidy and no spills or
other issues were noted around the site.

rain had caused overflow to the Kurapete
Stream. The discharge had no significant visual effect downstream in the receiving waters. Samples were
collected of the discharge, upstream and two sites downstream.

The primary screen was operating and wastes were fully contained. The pond level had been lowered in the
primary lagoon to allow a survey to be carried out around the wave band perimeter (remedial works are
planned during the 22/23 summer). The pond was turbid and

time of the inspection with 6.5 mm of rain falling over the previous 48 hours.
Monk Rd Site:
The discharged wood waste appeared to be very clean and free of unacceptable wastes.
The new pond pipe had been connected to the existing pipe that led down to the
culvert under Monk Rd. Due to low flow conditions the culvert at Monk Road was only
discharging undiluted contaminated spring water (i.e. no freshwater flow was

A site visit was made to conduct a compliance monitoring inspection and to take
groundwater samples. The weather was fine with 12 mm rain over the previous 24
hours.
Large areas of the crown of cap had been sown with grass. The re-grassed area had
been fenced off from stock. There were some areas of ponding around the stock
troughs and on the
in the skimmer pit under hot, sunny and
dry conditions, rather than any chemical source. The water level in the pit was very
low at the time of inspection. It was considered by Council officers that should
enough rain fall to cause a discharge, the pH would fall to well within consent limits
prior to any discharge occurring. No remedial action was required by the Council.
Also on 14 November 2012, a sample taken from the skimmer pit showed an elevated
suspended solids concentration. It
