Public Works Sewer Utility Maintenance

Sewer Utility

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 dechlorination and 
  • Spray irrigation of the reclaimed water.

The City has made improvements to the wastewater system of 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
