Two sites are monitored for ammonia. Both fall in band A, meaning ammonia is likely to have little to no
effect on all but the most sensitive species. Modelled estimates support monitoring results, with
approximately 82% of streams and
overabundance of algae and aquatic weeds, impact on the
growth of sensitive species, or even become toxic to freshwater organisms.
For ammonia, modelling suggests that all streams fall in band A (92%) or band B (8%) (Figure 4). Ammonia
is expected to have little to no toxic effect on all but the most sensitive species.
For nitrate, around 12% of streams fall within band A and aquatic species are unlikely to experience the
effects of nitrate. The majority of streams fall into band B (88%) (Figure

trench. The wastewater treatment system at the Retreat did not adversely affect the water quality of the
local freshwater and coastal environments. Although high bacteriological results were returned from the
routine sampling round in January 2019, these counts were attributed to surface runoff draining the
upstream agricultural catchment, following the rains that preceded the sampling. Two follow-up samples

was also some replacement of square kerbing with radial.
Mangaotaki Rockfall (2008)
Heavy rain triggered a large rock fall on 4th August 2008 at the Mangaotaki Bluffs. The large
rocks blocked SH3 for almost 48hrs and a route detour through local council roads was required
during this time.
Two stock truck effluent disposal facilities have been built along the route, one in each of the
regions – the Taranaki one at Ahititi on the northern
site.
1.3 Resource consents
1.3.1 Water abstraction permit
Section 14 of the RMA stipulates that no person may take, use, dam or divert any
water, unless the activity is expressly allowed for by a resource consent or a rule in a
regional plan, or it falls within some particular categories set out in Section 14.
The primary effects of taking and diverting groundwater is the potential for the water
table to be lowered, consequently impacting on nearby surface water such as the
westerly wind. The monthly rainfall was 210 mm of
rain as recorded at the Inglewood WWTP TRC weather station.
The step screen was operating and wastes were fully contained. Slight odour was noticeable in the vicinity of
the step screen. One aerator was operating on the aeration pond, which was a turbid, light grey brown
colour. The pond was discharging into the main pond.
The main pond had a normal level of 0.76 m, with a relatively clear, green grey colour and rippled surface.

1 Wowzers. It won't surprise anyone to see there was A LOT of
rain in February. Most of it fell over just a couple of
weekends, the 5th to 7th and the 11th to 13th. Our sites
recorded between 178% and 702% of normal rainfall, with an
average of 354%.

sites are monitored for ammonia. Three
out of four sites fall within band A and one
site in band B. At these sites, ammonia is
likely to have little to no effect on all but the
most sensitive species. Modelled estimates
support the monitored results, with
approximately 68% in band A and 32% in
band B (Figure 4).
Four sites are monitored for nitrate, all of
which fall in band A. At these sites, nitrate is
likely to have little to no effect on aquatic
life. Modelled estimates largely
period was lower than normal in
comparison with historical surveys. The total number of samples falling within the “Alert” or “Action”
categories (40% of samples) across the 16 recognised bathing sites was the highest recorded. However, it
should be noted that the “Action” category is the only category for which swimming is not recommended.
In the 2017-2018 season, 79% of all samples met the national bathing guideline. Of the 21% of samples that
exceeded the guideline, 11% arose
