IrriCalc guidance notes

The proposed NRRP allows consent applicants to use a model to estimate a seasonal volume that complies with the policies of

• 80% application efficiency
• Allocation for 80 percentile year
• Any method used to demonstrate this must be verifiable, and where a modelled approach is used, there must be sufficient data available to calibrate for the specifics of the location.

This document 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.

Condition Template Search

The Condition Template Search Tool enables consultants to look up and copy the condition text that Environment Canterbury's Consents Section uses. 
These templates can be used by consultants in consent applications. To use these templates, find the template needed and highlight the text and use the copy function (Ctrl+C on most keyboards) then paste into any Word document (Ctrl+V).
Please note: This is a new service and as such does not have many templates yet. As standard condition templates are reviewed internally, some will be added to this web page.
