Public engagement level: Advise

We are sharing information about project updates and maintenance / rehabilitation activities on site. We will listen to and acknowledge feedback and share how public input (if received) influenced our planned activities.

Public engagement framework


One of the Shared Outcomes created by EPCOR and the Community is ensuring a Reliable, Responsible and Sustainable operation. In relation to the Gold Bar Wastewater Treatment Plant, this Shared Outcome refers to EPCOR designing, maintain and operating the facility in a prudent and responsible manner. The following updates and developments are related to this Shared Outcome.

 Diversion structure rehabilitation

We're completing a structural rehabilitation of the underground channels (large concrete pipes) near the plant's main gate that receive and distribute sanitary flows. These channels have experienced significant deterioration, resulting in the need for rehabilitation. The first phase of the construction was completed in February 2020, and the second phase started in January 2020. Construction can only occur in phases and during the low flow months (October to February), as the full capacity of the infrastructure is required during the rest of the year. The third and final phase of the project started in the fall of 2020. Rehabilitation of all sections is expected to be completed by February 2022. Preparation for upcoming construction activities will occur in September of each year.


 Enhanced Primary Treatment air scrubber building

EPCOR is installing two additional Enhanced Primary Treatment (EPT) scrubbers in a new building as shown on the images below. The new building will align with the standards and recommendations included in the Architectural Guidelines created for the GBWWTP so it complements the rest of the facilities on site.

The new EPT air scrubbers will allow EPCOR to continue reducing odours in the area and provide redundancy for other scrubbers for additional reliability. The existing Enhanced Primary Treatment scrubber will remain in service. This project aligns with our long-term plans and commitment to odour mitigation and reduction from site. Construction has started on this project and we anticipate that the building will be constructed by early 2022.


In 2019, we engaged with the community through a series of workshops, events in your neighbourhood and an open house in June. During these events we provided information about the Renewable Natural Gas and Pipe Rack projects.  Please see the following updates regarding these projects.

 Renewable natural gas

The Renewable Natural Gas (RNG) project will allow EPCOR to capture a byproduct called biogas, which is otherwise used for process and plant heating or flared at the plant, upgrade it and transform it into renewable natural gas. This will reduce flaring, greenhouse gas emissions, and noise at the facility. Regulatory approvals for the RNG project (as shown on the image below) were granted in the fall of 2020.

Construction on this project is anticipated to begin later this year​​. The buried injection line shown in yellow below is underground and no trees will be removed outside of the fenceline to accommodate this project. Limited tree removal may be required inside our fenceline and revegetation will occur in alignment with our Landscaping Master Plan.


We originally notified the Community about the Renewable Natural Gas Project in 2019 through workshops, newsletters and our open house.  Find out more about this project.

 Pipe rack project

The above-ground pipe rack project was completed in 2020. There were no changes to the scope or design details associated with the project. Revegetation will align with the recommendations included in our Vegetation Plan.
