Water Treatment

The City of Medicine Hat operates a single water treatment plant complex located on the banks of the South Saskatchewan River within the municipal boundaries of The City of Medicine Hat. The original plant was constructed in 1914, with subsequent expansions in 1956, 1960, 1986, 1993, and 2004.

The current Water Treatment Plant is a 180 ML/D conventional treatment facility employing the use of solids contact up-flow clarifiers, dual media filters, secondary chlorine disinfection, and primary UV disinfection processes to produce potable water. Further expansion is scheduled within the next five years to develop a process waste treatment facility, located in close proximity to the Water Treatment Plant. This facility will treat all process waste generated from the Water Treatment Plant prior to discharge into the South Saskatchewan River.

The service area is located within the municipal boundaries of The City of Medicine Hat and includes specified bulk supply gates to Cypress County (including Seven Persons and Veinerville), bulk supply to the Greenvalley Water Co-op and the Roytal Water Co-op.

Wastewater Treatment

The City of Medicine Hat operates a Wastewater Treatment Plant complex located downstream of the Water Treatment Plant, on the east bank of the South Saskatchewan River. The original plant was constructed in 1961 with subsequent expansions in 1967, 1981, 1989, and 2009.

The current Wastewater Treatment Plant consists of a 75 ML/D mechanical treatment plant employing the use of primary and secondary treatment technologies, UV disinfection, and a polishing lagoon system. Treated effluent from this plant is discharged into the South Saskatchewan River in accordance to Alberta Environment Operating License procedures.

The service area is located within the municipal boundaries of The City of Medicine Hat and includes sanitary sewer collection and treatment services to The Town of Redcliff.

The City also operates a Class 2 landfill for solid waste. Runoff water and leeching of liquids exposed to waste are major concerns when operating a landfill. The primary system for containing runoff consists of a clay layer beneath the landfill. In the event that a large amount of water flows into the landfill, due to rain or flood, any runoff from the landfill will flow into a catchment pond meant to prevent the release of contaminated water into the environment. Any waste delivered to the landfill is covered daily, if possible. Since it is only a Class 2 landfill, hazardous waste is not accepted for dumping, and must be disposed of at a Class 1 landfill elsewhere.

Well water from the surrounding area is tested three times a year against Alberta Environment Guidelines. The landfill has the capacity to operate for another 20 years as of 2009.
