Well worth pond-ering
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
stored on site prior to
being piped to the Omata tank farm in New Plymouth. The gas is processed, compressed and piped to end
users. The produced water is disposed of by deep well injection.
Stormwater from the production station is collected and discharged at three separate points. The water level
in the firewater pond in the north western corner of the site is maintained by an abstraction from the
Ngaere Stream. Overflow due to rainfall entering this pond is discharged to land and to the …
rainfall events can
lead to rapid rises in river levels and flooding in hill country valleys and elsewhere.

The people
Figures from the 2018 census show Taranaki total population stands at 117,561, an increase of 7.3% over the
2013 census figure. In the previous census period (2006-2013) the region’s population increased by 5.3%.
Taranaki accounts for 2.5% of New Zealand’s total population.
Population changes have also varied

occurred on the 15 February 2017 and was the result of extremely high rainfall and an operational error.
Signage was placed at the affected sites in accordance with the contingency plan. The consent holder
subsequently undertook an internal audit of procedural matters and put in place remedial measures to
prevent a similar recurrence. In particular, monitoring and alarm system operation and response matters
have been re-addressed (STDC, pers comm).

Origin Energy Ltd’s Kauri D wellsite is situated in the eastern corner of the site, and
there is a small coastal lake inland and to the northeast (up gradient) of the storage pit
area. Both of these features are presented in Figure 1.

growing as mats on the rocks of a river bed
(benthic) or floating and drifting in lakes
(planktonic). During the summer months,
increased water temperature, reduced rainfall
and increased daylight hours provide ideal
conditions for cyanobacteria to grow, sometimes
resulting in algal blooms. When in bloom,
cyanobacteria can produce toxins that can pose a
risk to the health of people and animals entering
the water.
Sites monitored for benthic cyanobacteria were
suitable for recreational
as a result of high rainfall events that exceed the storage capacity of the primary and
holding ponds, and the pumping capacity of the reticulated system to Hawera.
Primary pond effluent analyses were not required during the monitoring period, although the condition of
the pond and any associated odour continues to be monitored during routine inspections.
