Incident an event that is alleged or is found to have occurred that may have
actual or potential environmental consequences
(STDC), operates the Eltham municipal wastewater
treatment system located to the east of Eltham in the Mangawhero catchment. STDC holds a
resource consent to allow it to discharge treated wastewater to the Mangawhero Stream
under high rainfall conditions only. Previously STDC also held a consent for the discharge
of emissions into the air but this expired in mid 2011 when it was no longer considered
necessary as the nature of the biological processes at the plant met a ‘permitted’ category in
Erosion and Sediment Control Plan that has been approved by the Chief Executive,
Taranaki Regional Council, acting in a certification capacity. This finalised plan shall
conform to the Waikato Regional Council’s Guidelines for Soil Disturbing Activities and
shall detail methodology/ design of stormwater drainage from the cleanfill, and
maintenance of sediment control practices, with a specific focus on rainfall events.

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.
Sampling of the discharge from the Kaimiro Production Station
There were no odours or visual issues near the WWTP or trenches at the time of inspection. There
had been significant rainfall preceding the site visit and STDC reported that high flows were continuing at
the time of inspection. There were several areas of ponding throughout the playground / reserve that were
partially barricaded off. The sea was a turbid brown at the time of sampling. Overall, the camp appeared to
be operating in compliance with its consent conditions at the time of inspection.
Whilst the
average daily discharge limit was exceeded on two consecutive days under high rainfall conditions, the
Company identified and eliminated stormwater discharges to the system in a timely fashion. Additional
operational changes were made to minimise daily discharge volumes. The wastewater treatment system at
the Retreat did not adversely affect the water quality of the local freshwater and coastal environments. The
results of this sampling suggested that the Retreat was not influencing
