​In 2017, EPCOR completed a four-year expansion and upgrade project to Regina's wastewater treatment plant. The project between EPCOR, the City of Regina and the federal government was required to meet stringent environmental regulations and to accommodate future growth.

EPCOR now operates the facility and provides an essential service to the Regina community by thoroughly treating more than 25 billion litres of wastewater each year before safely returning it back to Wascana Creek.
