Cathodic Protection Monitoring for Watermains

On September 27, anytime from 8:00 a.m. to 4:30 p.m, Green Pi will be collecting data from cathodic protection monitoring stations attached to some of the City’s watermains to gather information from the cathodic protection systems installed in 2021. The systems were installed to reduce corrosion that occurs throughout our watermain pipelines.

There will be no disturbance to community, traffic or otherwise except for parking contractor vehicles on the street and walking to the test station locations to take readings from the test stations.  Each Data collection point is estimated to take 10 to 15 minutes at each station. Data collection will occur on the following streets:

Data collection will occur at the following locations:

  • Carter Drive
  • Cheltonwood Avenue
  • Greenview Avenue
  • Gladstone Avenue
  • Metcalfe Street
  • Stevenson Street
  • Cathcart Street

Monitoring and data collection of the cathodic protection systems will occur twice a year in Fall and Spring until Spring 2024.
