groundwater table, BTW Company staff
undertook two bore permeability tests on the monitoring bores GND 2188 and GND 2190 (January
8th 2015).
The ‘slug test’ method requires removal of a set amount of water, where after recovery of water
levels is timed with a stopwatch. The four litre ‘slug’ was removed by a high rate vacuum pump,
and the recovering water level was determined with a calibrated electronic dip tape. Both
monitoring bores did not fully recover to their initial water levels after
appear to be improving. This is the highest percentage of sites
showing an indication of ecological improvement of any degree found to date. Surprisingly
and pleasingly, the number of sites showing improvement continues to be maintained at the
high levels of recent years, rather than begin to decrease as might generally be expected once
rates of improvement begin to flatten out.
Changes in the indicative and in the statistically significant trends are summarised below.

Water everywhere
New Zealand has one of the highest volumes of water
per capita flowing to the sea through some of the
shortest waterways in the world, over the course of
days rather than months (unless dammed).
The flow rate changes dramatically due to rain, and
the water often passes through an extreme range of
geography – from mountain, bush, forest, pasture and
towns.
within the permitted
activity rule [Rule 15] of the Regional Fresh Water Plan for Taranaki. That is, the
abstraction volume shall not exceed 50 cubic metres in any one day, and the rate of
abstraction shall not exceed 1.5 litres per second. The abstraction of water at the
Gully Rock Limited quarry is covered by Rule 15.
1.4.2 Water discharge permits
Section 15(1)(a) of the RMA stipulates that no person may discharge any
contaminant into water, unless the activity is expressly
abstracted for washing at quarries fit within the permitted activity rule [Rule 15] of the
Regional Fresh Water Plan for Taranaki. That is, the abstraction volume shall not
exceed 50 cubic metres per day, and the abstraction rate shall not exceed 1.5 litres per
second.
No consent for abstraction of surface water is required at this quarry. Wastewater and
washwater is recirculated to minimise the volume of discharge and to reduce the need
for water abstraction.
