Your responsibilities as owner of a private watercourse

​If you own a watercourse, you are responsible for ensuring that:

  • litter and pollutants do not enter the watercourse

  • grates or outlets within your property are kept clear of debris at all times
  • any work you do in relation to a watercourse must comply with the Stormwater Bylaw
  • any related earthworks must comply with the provisions of the Unitary Plan and the Stormwater Code of Practice.    

Examples of works done on a watercourse

  • Design and construction of pipes or other structures (requires a building consent[link])
  • Earthworks around or in your watercourse
  • Maintenance.
