shall cause not more than a 10% lowering of static water-level by
interference with any adjacent bore;
• The abstraction shall not cause the intrusion of saltwater into any fresh water aquifer.
Any produced water would be from reserves far below that which is used for
domestic or farm purposes. Shallow groundwater (which does not have any
saltwater content) was protected by casing within the bore hole. Given these factors,
the abstraction would not cause the above effects.
In
given they can be obtained
at a much lower capital cost. The low yields from Taranaki aquifers often mean that multiple bores are
required to supply high demand uses, making the use of groundwater uneconomic. Surface water systems
are generally able to sustain the majority of current water demand in Taranaki.
Notwithstanding the above, there is potential for growth in groundwater demand in the future. Any significant
growth would likely be driven by a shift in current land use, development
generator, others have plans to
truck effluent to the plant. There would be many
raw sewage overflows in a widespread power
outage lasting more than 2 days.
Solid waste management can be a critical issue in
a disaster (debris, volcanic ash, etc). A plan is in
place to use closed landfills if required.
All the major drinking water supplies in the
region are surface water supplies. They are
highly vulnerable to volcanic ash and there is
limited bore water

abstractions within
a radial distance of 1100 m from the proposed wellsite. Shallow groundwater (which
does not have any saltwater content) was to be protected by casing within the bore
hole. Given these factors, the abstraction would not cause the above effects.
In granting the consent it was considered that the taking of groundwater was
unlikely to have any adverse effect on the environment.

mixture of pasture and dune grasses. Test pitting and the logging of boreholes on site indicated a relatively
shallow water table. Test bores were augured to 10 m in the pit area, revealing extensive compacted, low
permeable clays underlying coastal dune sands. Pit construction revealed mostly tightly packed sand at the
pit bases (approximately 4-5 m below surface). Average annual rainfall for the site is 1,023 mm (taken from
the nearby ‘Duffy’ monitoring station). As with the other South Taranaki

Groundwater analysis results were obtained through the purpose built groundwater
monitoring bore network. Derby and Surrey Road facilities each have three
groundwater monitoring bores. These bore were installed to quantify the quality of the
groundwater and specifically to understand if any adverse effects were permeating
from either facility. Locations of each monitoring well are
