Public notice: Spraying operations

Thursday 21 September 2023

ORC Operations & Maintenance will be conducting scheduled drain spraying on the Taieri, Tokomairaro and Lower Clutha Schemes from 1 October 2023 to the end of April 2024.

The scheduled drains are in:

  • East and West Taieri
  • Tokomairaro
  • Lower Clutha

This activity is carried out to keep the drains in our land drainage schemes free from grass and weed build-up to maintain free-flowing capacity in the drainage network. The land drainage schemes ensure that the rural and some urban areas remain productive and liveable.

Work will be carried out by ORC staff and external contractors.

For any enquiries, please contact or call 0800 474 082.
