Wastewater is more than just the sewage you flush down the toilet: it’s also what you put down any drain in your home or business. All wastewater, or sewage, flows into the domestic sewer pipes located underground and if laid out in a straight line, Regina's 725 kilometres of sewer lines would almost reach Calgary.
Wastewater moves through the pipes by the force of gravity. Because Regina's landscape is so flat, we use lift stations in neighbourhoods to help continue the flow of wastewate all the way to the McCarthy Boulevard Pumping Station. It’s then screened and pumped to the Wastewater Treatment Plant (WWTP) located just west of Regina. The WWTP removes pollutants from the water before the treated wastewater, called effluent, is discharged into Wascana Creek.
The City owns and holds the Permit to Operate the Wastewater Treatment Plant. EPCOR has the contract to operate and maintain the plant.
The WWTP treats about 70 million litres of sewage from bathtubs, toilets, sinks and washing machines each day. Enlarge the image below to see how sewage is removed from wastewater.
