Drainage System

Edmonton's drainage system is managed and operated by EPCOR.

While the stormwater system is designed to handle typical rainfall across the city, extreme and prolonged rain can challenge or temporarily exceed capacity in localized areas. Saturated ground conditions can also increase the amount of rain entering the system.

During significant weather events, EPCOR deploys additional crews to monitor critical infrastructure, respond to customer inquiries and support emergency response efforts around the clock.

Flood Mitigation Investment

Over the past 5 years, EPCOR has invested approximately $350 million in flood mitigation projects, including dry ponds, low-impact development or green infrastructure, combined sewer separation and the relining of local sewers and manholes.

These investments are part of a 20-year, $1.6 billion flood mitigation program designed to help Edmonton adapt to extreme weather and reduce flood risk.
