Regina Wastewater Treatment Plant Field Trip

Bus departure

Location: U of R Kinesiology Bldg (CK), south main entrance (red star)

Time: 8:30 on Wed, Feb 14, 2024

Bus return

11:00 approximately. Our plan is to be back at campus before 11:30.

*Note that you must have all PPE for the tour. If you do not bring appropriate PPE you may not enter the bus to attend the tour.  PPE Required: Hard hat, Safety glasses, Vest, and Gloves. You must provide your own safety glasses.  You may borrow a hard hat, hi-vis vest, work gloves, by meeting Ben Lichtenwald at ED144 the day before at 10am, Feb 13 at ED144.

You may bring your own PPE instead of borrowing shared community PPE.

• Meets the new stringent environmental regulations. The plant is 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 can help improve the Wascana Creek ecosystem.
• Has the ability to 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.
• Features a wet weather flow storage system allowing us to store large extreme storm flows up to 450 ML/d and return the flow to the beginning of the process for treatment when the storm subsides. This adds significant robustness to the treatment process. (source: www.epcor.com )

The City of Regina Wastewater Treatment Plant Overview

The City of Regina Wastewater Treatment Plant is operated by EPCOR. Located west of the city it treats all its wastewater and discharges treated effluent to Wascana Creek. The main treatment scheme is a microbiological process which effectively removes organics and the nutrients nitrogen and phosphorus before final disinfection. The plant's design capacity is 157 ML/d.

Why attend this tour? Regina is a city far inland from the coast so this wastewater treatment plant cannot and does use the "dilution is the solution" axiom. This is an excellent tour for engineers and students. It's an opportunity to see a very large industrial plant up close. The facility takes about 100 ML/d of raw sewage from the city then by applying multiple unit processes converts it to a very clean effluent often better than the water you'd encounter in the receiving stream. You will see large scale handling of liquid, solid and gas phase pollutants. The facility was almost totally built through the 2010s to replace the old plant at the same site so much of the infrastructure, mechanical, and control systems are modern designs which you can observe in operation.
