With regard to consents for the discharge to water, the main points
of interest were plant processes with potential or actual discharges to receiving
watercourses. The neighbourhood was surveyed for environmental effects.
1.4.4 Bacteriological sampling
The Council usually undertakes bacteriological sampling in conjunction with the first
post-Christmas inspections in January. This year, sampling was carried out during the
final inspection round due to the rainfall that preceded the
of gravel bedloads.
The mountain and ranges have a strong influence on rainfall by producing orographic type
events which are often associated with frontal systems and depressions moving across the
Tasman Sea. Although the annual totals are quite high, the way in which rainfall is delivered is
more significant. Short duration, high intensity bursts of rain occurring during a storm event are
potentially much more significant in terms of runoff generated and related damage within the

these should be collected before the next rainfall event to prevent them entering waterways. There was a
low-flow discharge from the southern stormwater pond but not enough to collect a sample from. Water in
the stormwater drains was flowing. Water samples were collected from the remaining monitoring locations.
There was no foam or odour at any stream location.
2.1.2 Water quality sampling
Results of the two sampling surveys carried out in the 2022-20223 monitoring year are

factors like recent grazing, topography of the surrounding area and/or leachate generation from additional
stormwater infiltration. Since 2017 ammoniacal nitrogen has been consistently below 10 g/m3-N. Figure 3

Wetland quiz
Wetlands act like giant sponges, storing excess
water during heavy rains and releasing it slowly,
thereby preventing flooding. As a result, areas
downstream of wetlands still receive water when
rainfall levels are low. Wetlands help stabilize
shorelines and river banks.

The weather was fine at the time of the inspection with strong westerly wind blowing. Rainfall of 95 mm had
been measured over the preceding week at the Brooklands Zoo monitoring station. Stormwater pond
SV8000 contained 900 m3 of stormwater while SV9100 held 190 m3. The water was clear with some
