10. Definitions and abbreviations

The words in this Plan have the same meaning as in the Resource Management (Waitaki Catchment) Amendment Act 2004 or the Resource Management Act 1991, unless otherwise defined in this Plan or unless the context clearly requires otherwise.

In this Plan, the spelling of Māori words using ng and k is interchangeable (for example Ngāi Tahu and Kāi Tahu).

a.m.s.l.
Above mean sea level
Agricultural and horticultural activities
All activities involved with the primary industries of agriculture and horticulture, including common stock drinking-water schemes, but excludes processing agricultural and horticulture produce.
Allocation limits
The limits on the cumulative rate of taking and diverting of water that are established by this Plan and are specified in Rule 2 of this Plan.
Annual volume
The volume of water that can be taken or diverted in any 12-month period.
Any other activities
Activities that are not agricultural and horticultural activities, hydro-electricity generation, industrial and commercial activities, tourism and recreation facilities, or town and community water supplies.
Connected groundwater
(i) The full amount of water specified in a resource consent to take groundwater is considered connected groundwater if the effect of seven days groundwater abstraction on the surface water body is equal to or greater than 90 percent of a continuous steady abstraction rate.
Otherwise
(ii) The stream depletion effect is considered connected groundwater provided it is greater than 5 l/s. The stream depletion effect is that determined as the effect after 150 days groundwater abstraction at a continuous abstraction rate consistent with the flows specified in the resource consent.
Deemed permit
A permit derived from a mining privilege in respect of water, as defined in section 413(1) of the RMA.
Environment Canterbury Report UO5/15
"Schedule WQN9 Revision - Review of seasonal use approach included in proposed NRRP". Report U05/15, May 2005. Prepared for Environment Canterbury by Anthony Davoren and David Scott.
Ecosystem
Plants, animals, their physical environment, and the dynamic processes that link them.
Environmental flow and level regimes
The flow-sharing, allocation limits, minimum flows and levels and flushing flows established by this Plan.
Fisheries and wildlife
Activities relating to the management and enhancement of habitats of fish and indigenous wildlife.
Flow-sharing
The apportioning of flow between in-stream uses and the cumulative taking and diverting of water, as specified in Rule 2(c).
Flushing flows
Flows passing or released from a dam to prevent siltation and build-up of filamentous algae in the river downstream of the dam.
In-catchment needs
Water requirements of users where the water is taken or diverted for use within the Waitaki catchment.
Industrial and commercial activities
Industrial and commercial activities (but excluding hydro-electricity generation) that are not served by a reticulated town and community water supply.
Instantaneous rate of abstraction
The rate at which water is taken at any point in time.
Irrigation application efficiency
A measure of the amount of applied water that is stored in the crop root zone, as a proportion of the average depth of the water applied to the crop.
Iwi Management Plan
A relevant planning document recognised by Te Rūnanga o Ngāi Tahu, and lodged with the council.
l/s
Litres per second.
m3/s
Cubic metres per second.
Mahinga kai
Food and other resources, the gathering of those resources and the areas that they are sourced from.
MALF
Mean annual low flow.
Mauri
Essential life force or principle; a metaphysical quality inherent in all things, both animate and inanimate.
Mean annual low flow
The average, for a number of years, of the annual lowest daily flows. This is determined by selecting the lowest daily flow (average over 24 hours) for each year of record, summing those values and then dividing the total by the number of years of record.
Micro hydro-electricity generation
The generation of hydro-electricity not exceeding a capacity of 50 Kilowatts continuous output.
Minimum flow and level
Minimum lake level
The flow or lake level at which the taking and diverting of water from a water body authorised by a resource consent must cease. In the case where a river is dammed, inflows and outflows must be managed to maintain or exceed the minimum lake level and the minimum flow downstream.
Natural flow
The flow that would have occurred if the Waitaki Power Scheme had not been installed.
Natural Resources Regional Plan (NRRP)
Proposed Canterbury Natural Resources Regional Plan adopted by the Canterbury Regional Council on 28 March 2002 and publicly notified on 1 June 2002 for submissions, including variation 1 to that plan, adopted by the Canterbury Regional Council on 27 May 2004 and publicly notified on 3 July 2004 for submissions.

The collection of individuals who descend from the primary hapū of Waitaha, Ngāti Mamoe, and Ngāi Tahu, namely Kāti Kurī, Kāti Irakehu, Kāti Huirapa, Ngāi Tuahuriri and Kai Te Ruahikihiki.
Priority bands
A method for managing run-of-river takes and diversions to ensure a known reliability of supply such that all users within a priority band will be subject to the same restrictions.
Property
Any contiguous area of land held in one, or more than one, ownership that is utilised as a single operating unit, and may include one or more titles.
Rate of abstraction
The rate at which water is taken at any point in time.
RMA
Resource Management Act 1991.
Shallow groundwater
Groundwater having an average depth (assessed at the point of take) below the land surface of less than 10 metres.
Technical efficiency
Using a resource in a way that any given output is produced at least cost, including avoiding waste.
Tourism and recreation facilities
Tourism and recreation facilities that are not served by a reticulated town and community supply, such as hotels, lodges, restaurants and ski fields.
Town and Community water supplies
Reticulated water supplies servicing urban areas, rural-residential and residential subdivisions including all commercial and industrial premises and schools and other educational facilities located within the reticulated area.
Waitaki Act
Resource Management (Waitaki Catchment) Amendment Act 2004.
Water-users group
A group of users with existing authorisation to take water.
Wetland with a moderate or higher significance
A wetland that has been assessed and has been classified as moderate or higher significance in accordance with the criteria and methodology in Appendix WTL1 of the Natural Resources Regional Plan.
