Annual testing and inspections of infrastructure designed to protect water pipelines against corrosion across parts of Brisbane and Ipswich are now in progress.

Cathodic protection systems protect metallic structures, such as underground pipelines, from corrosion. They do this by converting anodic (active) sites on the metal surface of a structure to cathodic (passive) sites. There are two types of cathodic protection – sacrificial and impressed current.

Seqwater contractors will be accessing roads, parks and properties between April and May 2017 to test and inspect cathodic protection systems in the following suburbs:

  • Acacia Ridge
  • Anstead
  • Archerfield
  • Aspley
  • Bellbowrie
  • Chapel Hill
  • Darra
  • Kenmore
  • Mount Crosby
  • Pinjarra Hills
  • Riverhills
  • Stafford
  • Sunnybank Hills
  • Wacol

Working hours are between 7 am and 5 pm, Monday to Saturday. Equipment will include hand tools and testing devices only, and work is not expected to interrupt water supply.
