Lethbridge Wastewater Treatment Plant-2014
History of the Lethbridge Wastewater Treatment Plant
Wastewater Treatment Plant Process
The City’s Wastewater Treatment Plant and Utility is funded by revenue from residential and commercial wastewater rates.
Our wastewater collection system consists of 520 km of sewer and 19 lift stations. The sewers and lift stations convey wastewater from residences and businesses in all areas of the City to the wastewater treatment plant. The treatment plant removes contaminants from the wastewater and discharges clean, disinfected effluent into the Oldman River south of Peenaquim Park.
Several steps are required to treat our wastewater with the capacity to treat 80 million litres of wastewater a day.
- Primary Clarifiers
- Liquid Treatment Processing-Step BioP
- Secondary Clarifiers
- Ultra Violet (U.V.) Disinfection
- Final Effluent Treatment
- Sludge Treatment Processing-Digesters
- Using Sludge as Fertilizer
- Methane Gas
