Sewer Infrastructure

The City of Armstrong Wastewater Treatment Plant currently provides treatment for domestic and industrial wastewater generated within the City. Our wastewater system incorporates the following components: 

  • Preliminary treatment of the influent wastewater
  • Secondary treatment in a multiple cell partial-mix aerated lagoon system
  • An aerated storage reservoir for the treated effluent
  • Chlorine disinfection followed by de-chlorination
  • Spray irrigation of the reclaimed water.

The City has made improvements to the wastewater system over the years. As it stands, the current system has two main sites: 

  1. The influent pumping, preliminary treatment, Lagoon Cells 1-4 and a high lift pumping station located within the City 
  2. Two additional aerated lagoons Cells 5-6 are located within the Township of Spallumcheen
