General consent tools

Consent search
You can search consents here.
Well search
Our well search displays a summary of information that we have on a specified well or bore. Click here.
Well interference assessment tool
Our groundwater Well Interference Assessment tool is a web application that allows you to create a PRN file directly from our well and resource consent databases.

IrriCalc
The Canterbury Land and Water Regional Plan allows consent applicants to use a model to estimate a seasonal volume that complies with Schedule 10.

Use a model that has been field validated and shown to reliably predict annual irrigation volume within an accuracy of 15 per cent.

The annual volume calculated using the model shall be complaint with the following criteria:

  • an irrigation application efficiency of 80 per cent
  • a system capacity to meet peak demand (half a litre per second per hectare)
  • a nominal irrigation season from September 1 to April 30, and
  • demand conditions that occur in nine out of 10 years.

Download the Irricalc Guidance Document (PDF File, 59.29KB) for detailed information.

  • Section 1 sets out the criteria and requirements for a model and its application to estimate seasonal irrigation water use and to set seasonal irrigation water use limits.
  • Section 2 is dedicated to providing guidance on how to calculate a farm's seasonal irrigation water limit using the IrriCalc maps.
  • Section 3 provides answers to some of the main questions associated with using the IrriCalc model.
Annual volume calculator
This is an Excel spreadsheet for you to calculate an annual volume for a specific area of irrigated land.
To use the calculator, you will need some specific technical information about your actual or intended irrigated area.
Whether you already have an existing consent for the area or your interest is in applying for a new consent, the valuation or legal description for all relevant land parcels will be helpful. Alternatively, you can search by entering the name of an adjacent road.
If you want to calculate the annual volume for more than one consent or if land parcels are geographically separate, you will have to run a separate calculation for each consent/land parcel.

You will need the following information from your pumping schedule:

  • The maximum volume (actual or intended) per Return Period. Return Period is the time (in days) between successive irrigations.
  • Length of return period (actual or intended).

To find this information:

  • Check the consent details sent to you from Environment Canterbury or search using our consent finder
  • The instructions on the use of the spreadsheet show how to determine the maximum volume if it is not explicitly stated in an existing consent.

You will also need to know:

  • the area (in hectares) to be irrigated
  • land-use type (actual or intended) e.g. arable, intensive pasture
  • Profile Available Water (PAW)
  • effective irrigation season rainfall.

To find this information:

Information on Profile Available Water (PAW) and effective irrigation can be obtained using Canterbury Maps.

Erosion and sediment control training
We hold training workshops, produced by us in consultation with the earthworks industry, to provide practical advice about on-site measures. These will help you meet resource consent conditions and prevent waterway and dust-related pollution.
With the help of our sponsors, Geofabrics, MBC and RST Environmental Solutions Ltd, we offer two training workshops led by Campbell Stewart. You can read more about him at SouthernSkies Environmental Limited where he is a director. 
Course 1: Introduction - For Earthworks Site Contractors
  • Course date: as needed

This is a one-day workshop for those who are involved or interested in the building, operation, maintenance or decommissioning of measures set out in erosion and sediment control plans. This workshop provides a background understanding of erosion and sediment control methods and the environmental effects of sediment.

To register: erosion.sediment@ecan.govt.nz
Course fee: TBC

Course 2: Introduction - For Consultants, Local Authority Staff and Earthwork Site Managers

  • Course date: as needed

This is a one-day workshop for consultants (who lodge consent applications for earthworks and stream works, prepare assessments of environmental effects and erosion and sediment control plans in support of these and who call for tenders for the approved works), site contract managers, local authority staff (involved with policy, consenting and compliance associated with earthworks and stream works) and those wanting a detailed working knowledge of erosion and sediment control.

This workshop provides a background understanding of erosion and sediment control methods and the environmental effects of sediment. Time is also spent visiting a greenfield development site and preparing an erosion and sediment control plan.

To register: erosion.sediment@ecan.govt.nz
Course fee: TBC

 Conditions of training courses: 

  • The site visit is reliant on availability and is not guaranteed. We will always do our utmost to include a site visit but if situations arise beyond our control then this may not be part of the workshop.
  • Registration confirms placement for attendee in the required workshop. If for any reason the attendee is unable to attend the workshop then a minimum of 48 hours notification to the workshop organiser is required. The ideal situation (should the registered attendee not be able to attend the workshop) would be that the registered attendee arrange a substitute to take the original attendee's place.
  • Cancellation of an attendee outside of the 48 hours minimum notification without replacement will incur the schedule workshop fee.
  • Attendance is limited to 20 people at each workshop.

Builder's pocket guide

People who are constructing houses on small sites or companies managing the construction of commercial sites can refer to the builder's pocket guide for small sites (PDF File, 1.78MB).

Erosion and sediment control guidelines

The erosion and sediment control guidelines is a set of guidlines for anyone involved with any type of earthworks on the land or near water—projects large and small. They provide guidance for minimising the adverse effects of erosion and sedimentation while planning, constructing and maintaining a project.
