cap. There were no cattle visible during the inspection. The perimeter drains contained flowing water that
was clear. Some surface water was present in the drain near the flume shed, but this was not discharging
towards the Pātea River.

note that Council expects that all consents issued will require an exclusive
discharge to land and full storage after 1 December 2022. This means that any
consented discharge expiring in 2022 or later must discharge to land.
Dual discharges may be allowed if the farm is in a high rainfall area and provision of
adequate storage is impractical. This option needs to be discussed with Council Staff.

foreseeable flow scenarios.

Productive Land
Land is one of our most valuable assets, providing
recreational opportunities and giving us a sense of place
and connection to our local environment. Farming and
forestry provide dairy, meat, wool and timber products
that contribute significantly to the regional economy and
support communities.
The natural variations of climate, topography and soil shape
how land is used and managed across the region. Regular
rainfall and deep, fertile
terraces, coastal environment, eastern hill
country. 530 named rivers, many steep,
short and narrow.
One of the highest areas of rainfall in NZ but
also experiences periods of drought. Its
location by the Tasman sea means high
winds, tornadoes and cyclones are a
regular occurrence and expected to
increase with climate change
Taranaki is NZ’s largest and most important
oil and gas-producing region.
A number of gas-powered electricity
generation plants are
stormwater upgrades at the site have included an additional sediment settling pond being added to
the stormwater system (Photo 4). This discharges to the stream via a new pipe (STW002101) into the same
manhole as STW002016. The original connection from the skimmer pits (STW002016) has been retained so
that during times of high rainfall the flow can come directly from the skimmer pits rather than flushing out
the sediment settling pond.

discharge to the stream.

2.1 Inspections
18 September 2018
An inspection was conducted in cloudy weather with light northerly wind conditions. The rainfall recorded at
the Inglewood WWTP council weather station in the month prior was 147 mm.
NPDC contractors were onsite carrying out maintenance around the primary screen influent area. Mild
odours were noted in the vicinity of the step screen. The primary
