wastewater discharge.
Piggery discharge records were checked, and six separate discharges to the Rumkeg
Creek had been recorded to date.
Because of several unsubstantiated odour complaints received by the Council, the
consent holder had installed a weather monitoring station at the piggery. Noted were
wind direction (south east), wind speed14.5 km/hour and rainfall volume (77 mm in
last 24hrs).

On 20 June 2013
Piggery discharge and receiving water samples were collected after a recent heavy
rainfall event throughout the upper Manganui catchment. The Rumkeg Creek staff
gauge was reading 0.58m at the time of sampling, equating to a river flow of 5.028
m3/ sec. The piggery discharge flow rate was estimated at 8-10 litres per sec. The
piggery manager had only discharged treated effluent wastewater to the
considered necessary
to define what the acceptable error is for each relevant consent condition.
This discussion between the Council and the Company is ongoing, and it may be determined that it is
better to define this error through the consent renewal process, which is anticipated to begin in 2021.
In the 2017-2018 period there was only one occasion where such limits were breached. This occurred on
27 July 2017 during a severe weather event. Significant rainfall occurred in the Mangaotea
kōura (freshwater crayfish) were a
staple harvest with large numbers of kahawai and pātiki (flounder) also caught on the river mouths along the
Taranaki Iwi coastline. Although access to many of the age old fishing spots for piharau has become a
challenge, many are still caught in the months of June, July and August by Taranaki Iwi families.
Relatively high rainfall up on the mountain quickly drains through these river systems, contributing to high water
flows and the swift
Council’s Director-
Environment Quality, Gary Bedford. “The coastal sites look
even better.”
He says that while the word ‘swimmability’ rolls easily off
the tongue, the concept is fraught with complications and
questions. “A river in full flood and laden with debris after
heavy rainfall could never be sensibly regarded as
swimmable, no matter what the bacteria levels may be.”
He also says it’s important to note that E. coli are simply an

The dry start to 2015, followed by a brief spell of intense rainfall in
early February, highlighted the importance of sound dairy effluent
management practices.
“We’re finding a few common pitfalls that can lead to non-compliance
with dairy effluent discharge consent conditions during abnormally dry
or wet weather,” says the Taranaki Regional Council’s Compliance
substrate combined with low rainfall at the beach
would be restricting the production of leachate from the green waste.
