irrigation was high. Most irrigation had
commenced by the middle of December.
Over the five month summer irrigation period, Mount Taranaki recorded between 69% and
88% of normal rainfall which meant that rivers were running well below mean flows for the
entire period. The low stream flows necessitated close and frequent monitoring by the Council
to ensure ecological flows were maintained in those waterways being used to supply water for
irrigation. During the period under review compliance with
pre-treatment of industrial wastes is maintained to a
satisfactory standard at all times prior to discharge into the WWTP.
No odour was detected beyond the boundary during any of the four routine inspections.
Results of effluent monitoring
With the diversion of wastes to the Hawera WWTP in the 2010-2011 period, discharges from the Eltham
WWTP now occur only as a result of high rainfall events that exceed the storage capacity of the primary and
holding ponds, and the pumping capacity of the
Council meeting agenda November 2019
for irrigation was high. Most irrigation had
commenced by the middle of December 2014.
Over the five month summer irrigation period, rainfall was between 62% and 106% of normal
which meant that rivers were running well below mean flows for the entire period. The low
stream flows necessitated close and frequent monitoring by the Council to ensure ecological
flows were maintained in those waterways being used to supply water for irrigation. During
the period under review compliance with
sites (Waingongoro River
at Ohawe, Kaupokonui River at the mouth, and Waiwhakaiho River at the last riffle and at
Merrilands Domain) on a total of 17 individual site surveys, and detaching or detached mats
accumulating on the river’s edge triggered the ‘Alert’ level at the same four sites on a total of
15 surveys. Levels of cyanobacteria were lower than in the previous four seasons; the
improvement was probably caused by above-average rainfall causing a large number of
freshes that scoured
consent requirement. The reduction of
stormwater infiltration entering the reticulation, remains an issue to be minimised, with
some overflow issues occurring during the monitoring period, due mainly to excessive
inflows at the inlet of the plant following a very intensive rainfall event in mid-June 2015.
Remedial work undertaken to improve the hydraulic capacity of the new outlet and outfall
design together with additional sealing of the second pond’s cells’ walls has been successful
in
landowners while the Government sorts out the wide ranging and many
detailed technical and operational problems with the NZ ETS and consulting directly with
industry and forestry interests.
The Climate Change Projections for New Zealand report analyses expected changes in New
Zealand’s climate such as temperature, rainfall and other climate variables, out to 2120, and
draws heavily on climate model simulations from the Intergovernmental Panel on Climate
Change (IPCC) Fifth Assessment report. For
in rainfall patterns have
caused difficulties at various sites in the past as localised rainfall may impact on
bacteriological quality on isolated occasions]. Where necessary, a 2 metre sampling
pole was used for bacteriological sample collection immediately beneath the water
surface and at a minimum of calf depth at the sites. Thirteen samples were collected
from each site during the season.
Samples were analysed for enterococci, E. coli and faecal coliform bacteria, turbidity

and any points of interest be discussed in this item on the agenda. A template will be
issued prior to the next meeting. Members agreed that they will respond to these in future.
Item 10: Forthcoming Events (standing item)
Shared by Marcia that TRST have some events coming up that she is happy to share with
the minutes, but the main two are;
• They have four rural woman events coming up and one for migrant communities.
General Business
Shared that the region has a heavy rainfall
