Wastewater/Sewer

All wastewater, or sewage, flows into the domestic sewer pipes underground. If laid in a straight line, Regina's 725 kilometres of sewer lines would nearly reach Calgary. Wastewater is what you flush down the toilet and pour down the drain in your home or business. If the wrong items are going into the sewer system, there is a potential for plumbing issues, increased utility costs and impact to the environment. Find out what items are appropriate for flushing into the toilet, draining in a sink, or pouring into a catch basin.

Wastewater moves through pipes by the force of gravity. Because Regina's landscape is so flat, we use neighbourhood lift stations to help continue the flow of wastewater 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.
