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

and is then pumped to the effluent treatment plant and discharged via the
marine outfall. Stormwater from the tankage area is pumped over into the process sewers which flow to the
storm pond. The stormwater falling on the non-process areas of the western half of the site (Figure 1) is
directed by “v” ditches running alongside the roads to a dam/pond and then out to the Tasman Sea via the
Manu Stream. Stormwater falling on the eastern side of the site is directed to unnamed tributaries of the

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
occurring from

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
Inspection was carried out during wet weather following a period of rain throughout the
catchment. The influent screen was operating and wastes were fully contained. The main pond was dark
green/brown with a turbid appearance. A mild odour was noted downwind. Wildlife was numerous, with
over 450 mallard, paradise and teal ducks, Canadian geese and black swans.
Both wetland pond levels were normal. These were dark green/brown in colour and slightly turbid. No
ponding was noted in the vicinity of

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
