​In June 2020, EPCOR submitted an application to the Alberta ministry of Environment and Parks to renew our approval to operate the Edmonton waterworks system. In accordance with the Environmental Protection and Enhancement Act (EPEA), we renew this approval every 10 years. We received our most recent approval to operate from Alberta Environment and Parks in 2021. You can find more information about our application and the regulatory process below.

Our Regulators

Environment and Parks, under the Environmental Protection and Enhancement Act (EPEA), is responsible for regulating drinking water systems in Alberta that treat raw river or groundwater and distribute to customers. We follow strict regulations to ensure monitoring and water quality provisions are in place at all of our water treatment facilities.

Under the EPEA, EPCOR is required to apply for renewal of our existing approval every 10 years, or whenever we make substantial operational changes to our waterworks system. Renewing our approval to operate is an important part of our commitment to excellence. The renewal process helps to ensure our testing parameters continue to be at the highest level and it allows us to continue engaging stakeholders in a meaningful way to discuss how we operate our water system.

Edmonton Waterworks System

In the Edmonton waterworks system, raw water is drawn from the North Saskatchewan River. It is then treated at the Rossdale (9469 Rossdale Road) and E.L. Smith (3900 E.L. Smith Road) water treatment plants in Edmonton.

Our drinking water meets or exceeds all of the requirements set by provincial standards and Health Canada's Guidelines for Canadian Drinking Water Quality. EPCOR's water quality assurance laboratory tests and adjusts for more than 300 parameters so that we can provide you with the best drinking water for safety, colour, smell and taste.

The two water treatment plants' onsite reservoirs and high lift pump stations supply potable water into Edmonton's transmission system's piping network primary zone.

The high lift pump stations are supported by:

    • 10 reservoirs and pump station sites;
    • seven booster stations which supply a network of transmission and distribution pipes into the entire Edmonton area; and,
    • eight supply points to regional water customers in the surrounding communities.
