EPCOR reached substantial completion of the Regina Wastewater Treatment Plant upgrades in December 2016.  Upgrades to the plant were required to meet the Province of Saskatchewan's higher effluent standards. The new facility is designed to meet environmental standards and the needs of a growing population.

Since December 2016, the plant has been operating and meeting the Province's new, more stringent environmental standards. 

The next step in the process is to reach final completion and independent certification of the plant. 

Current phase

  • The plant is currently in the performance test phase. 

  • In order to meet the final completion milestone, the plant must pass the performance test and obtain independent certification.

  • Read more in this backgrounder and report to Regina City Council.

Healthier rivers and aquatic life

The new facility will meet higher effluent quality requirements specifically regarding the reduction of nutrients that can damage to water bodies thus improving conditions for aquatic life" The treatment solutions will also reduce nutrients that can damage the environment from re-entering the river and will improve conditions for any aquatic life in the Wascana Creek and Qu'Appelle River system.

On time and on budget

This project is a priority for us and for the City of Regina. Delivery safeguards are in place according to best Public-Private Partnership practices to ensure the facility is delivered at a high standard and according to the agreed upon schedule and budget.

Service Regina

Regina citizens should continue to contact Service Regina for any inquiries related to:

  • Sewage bills
  • Sewage backup
  • Flooding or drainage concerns
  • Water service
  • Water quality issues

The City of Regina continues to own the Wastewater treatment plant, which is regulated by the Saskatchewan Water Security Agency.

Project timeline

Since August 1, 2014 EPCOR has been operating the Wastewater Treatment facility while constructing the new process components and upgrading the existing plant. We'll then continue to operate the wastewater treatment facility until June, 2044.

New facility features

In order to accommodate Regina's population growth, the new wastewater treatment plant will have:

  • Significantly more capacity than the previous plant.
  • We can treat more flow coming into the facility. The plant is designed for 156 ML/d of full treatment and 197ML/d for a short duration versus the maximum of about 100 ML/d that existed prior to upgrades.
  • A wet weather flow storage system allowing us to store large extreme storm flows during wet weather events and return the flow to the beginning of the process for treatment when the storm subsides. This will add significant robustness to the treatment process.

In addition, the new treatment process:

  • Meets the new stringent environmental regulations. The plant will be an ISO14001 accredited facility.
  • Utilizes a biological process, lessening the use of chemicals and reducing potential pollutants and chemical costs.
  • Produces a higher quality effluent which will improve the Wascana Creek ecosystem.
  • Has the ability to respond to higher or lower water flows more quickly than the current plant.

What to expect during regular operations

Noise

Noise associated with construction will be limited to hours of operation and are not expected to exceed allowable levels (defined by local bylaws). During these hours, noise will be controlled through monitoring and suppression activities.

Odours

Nuisance odours aren't expected to change. We also have a plan to control potential smells emanating from the new wastewater system.
