must satisfy. These consents allow the
Company to take water from a pond and discharge treated wastewater into an unnamed
tributary of the Heimama Stream at the Wiremu Road quarry.
The Council’s monitoring programme for the period under review included four inspections.
No water samples were collected for physicochemical analysis.
Monitoring found that the site was generally well managed and tidy. Inspections found no
indication of adverse effects in the receiving waterbody from the
tower is drawn from the Patea River via the existing abstraction and storage
system for the combined cycle plant. Wastewater is discharged to the Patea River. Site stormwater is
transferred to the raw water holding pond at the combined cycle plant during operation. Domestic wastes
are discharged to a land-based system which was upgraded in September 2018.
1.3 Resource consents
The Company holds 17 resource consents, the details of which are summarised in the table below.
Summaries of the
overall good level of
environmental performance.
The Council’s monitoring programme for the year under review included three routine inspections of the
wastewater system, one inspection of the rock wall, and routine bacteriological water sampling of the Wai-
iti Stream and Wai-iti Beach on one occasion.
Two additional bacteriological water sampling rounds were also undertaken to monitor any impacts of the
unnamed tributary on the Wai-iti Stream, following recommendations made in the

Wood Group M & O holds water discharge permit 1228-4 to discharge treated
stormwater and wastewater from fire fighting at the Fire Training Centre at the Maui
Production Station to the Oaonui Stream. The permit was first granted in 1975. The
latest renewal was issued by the Council on 11 October 2000 under Section 87(e) of the
RMA. It is due to expire on 1 June 2018. STOS previously held this discharge permit. As
the consent relates to the Maui site
monitored by the Council under the Eltham wastewater treatment plant/Eltham landfill combined
monitoring programme.
Historically the water quality in the Mangawhero Stream was quite poor due to the discharges from the
Eltham wastewater treatment plant and it was difficult to fully access any impact from the landfill on the
stream. Generally no deterioration in water quality was found when comparing upstream and downstream
sites.
Now that the Eltham wastewater treatment plant pumps its
time and hours of irrigation;
b) The volume of waste water irrigated to land;
c) The conductivity of the irrigation fluid (measured in mS/m)
d) The source of the waste water [e.g. Pond or Wetland Treatment System]; and
e) The location and extent where the wastewater was irrigated.
Condition 9 There shall be no direct discharge to water as a result of irrigating wastewater
to land. This includes, but not necessarily limited to, ensuring the following:
a) No irrigation shall occur closer

coliform numbers were obtained using the mTEC agar method #9213-d, Standard Methods for the
Examination of Waters and Wastewaters (APHA, 2005). Enterococci were quantified using the EPA modified
method #1600 on mEI agar (EPA, 1986).
In the 2017-2018 summer period, it was decided to stop analysing for E.coli and faecal coliforms, in order to
optimise the efficiency of the laboratory; given the increase in overall sampling intensity in recent years.
E.coli and faecal coliforms are inferior …
