note that Council expects that all consents issued will require an exclusive
discharge to land and full storage after 1 December 2022. This means that any
consented discharge expiring in 2022 or later must discharge to land.
Dual discharges may be allowed if the farm is in a high rainfall area and provision of
adequate storage is impractical. This option needs to be discussed with Council Staff.

Productive Land
Land is one of our most valuable assets, providing
recreational opportunities and giving us a sense of place
and connection to our local environment. Farming and
forestry provide dairy, meat, wool and timber products
that contribute significantly to the regional economy and
support communities.
The natural variations of climate, topography and soil shape

Hill Country FMU is under-represented in the monitoring network with only one monitoring site.
At a catchment level, the monitoring sites generally over-represent catchments with:
mean annual temperature <12°C;
mean annual effective precipitation >1500mm;

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

downstream of the dam, and allows for a lower minimum flow when less than normal
rainfall reduces inflows.
Conditions 9 to 12 define the minimum and maximum allowable lake levels for winter
and summer periods, specify the required spillway gate settings during a high lake
level, and allows for some flexibility in lake levels to allow for a short term electricity
shortage. When such a shortage occurs, the consent holder is required to notify

data were sorted into arrays for each individual year, and then ranked from the highest to
lowest values. After discarding the highest 5 (1) percent of the ranked values for each year
the next highest values for each year are the 95th (99th) percentiles
In this report the 95th (99th) percentiles of daily maximum gust speed will be called the
‘extreme intensity’. The frequency of daily maximum gust speed exceeding the 1972-2006
mean 95th percentile rainfall values will be called the
climate change out to 2100, would use an increase in peak flood flows of
approximately 20%. This is based on the latest NIWA report prepared for MfE (HIRDs V4). That report states for every
degree of temperature increase there is a corresponding 10.1% increase in rainfall (this is called the augmentation factor).
Using the RCP6 climate change scenario out to 2100 (the mid-range CO2 emission scenario) this gives a 2.0-degree
temperature increase or an equivalent increase in rainfall
undertaken within three days following significant river
freshes. However, occasionally sampling was affected by localized rainfall and
elevated river flows. An additional seven samples were taken at five of the beaches
(Onaero, Fitzroy Ngamotu, Oakura and Opunake) regardless of weather conditions for
the purpose of MfE monitoring (as discussed in Section 3.3.1). All results within this
report are presented and discussed on a site-by-site basis for the sampling period. The
