Septage hauling program

The Wastewater Treatment Plant operates a septage hauling program for residents that are not connected to the municipal sewage system. This service is only for depositing septage; no other waste will be accepted under this program.

This service requires septage haulers to complete a Hauled Waste Discharge Permit Application Form.

Wastewater collection

The sanitary sewer and collection system collects and transports wastewater sewage from all residential, industrial, commercial, as well as other facilities connectedto the sewer system to the wastewater treatment plant. The collection system is composed of gravity sewers, forcemains and pumping stations.

The City's collection system is monitored continually and operated within compliance of all applicable legislation. Staff that maintain and operate the collection system are licensed and required to follow all regulatory requirements.

Wastewater collection staff is responsible for the maintenance of sanitary and storm infrastructure, CCTV camera, cleaning and pipe repair, catch basin and manhole restoration, as well, maintenance of the City's landfill leachate collection system. Staff also participate in confined space entries and spill response.
