Water treatment - making your water fit to drink

Dunedin’s water treatment plants use a variety of treatment methods to make the water clear and safe to drink. Raw water from the catchments can be dirty or contain harmful bugs, especially if there has been heavy rain. Each treatment plant also receives a grade from the Ministry of Health.

  • Two main treatment plants, Mt Grand and Southern, service the majority of Dunedin.
  • The new Southern water treatment plant was commissioned in July 2005.
  • Mosgiel’s water is treated by five separate treatment plants.
  • Port Chalmers water treatment plant is generally operated in the summer months only.
  • The Outram treatment plant treats water for the Outram township.
