Monitoring wastewater for COVID-19

UCalgary researchers are working with community partners to detect traces of SARS-CoV-2 in Calgary's wastewater

A faster way to detect clusters of COVID-19 infection in the population is critical to avoiding future outbreaks — and what’s going down your drain could help public health officials catch outbreaks sooner.

UCalgary researchers from the Cumming School of Medicine, Faculty of Science, and Schulich School of Engineering; Advancing Canadian Water Assets (ACWA), The City of Calgary, and Alberta Health Services (AHS) teamed up to test Calgary wastewater for early signs of COVID-19 cases. 

As of July 1st, 2023, the Alberta COVID-19 wastewater monitoring program has been transitioned from the University of Calgary and University of Alberta to Alberta Health (AH) and Alberta Precision Laboratories (APL). The CHI Tracker will continue to be a resource for Albertans, as we will share the COVID-19 wastewater monitoring data generated by AH and APL.

Frequently asked questions

What is Wastewater-based Epidemiology (WBE)?

Wastewater-based Epidemiology (WBE) is the process of analyzing wastewater to measure levels of selected substances. It is a method of monitoring for pathogens such as SARS-CoV-2, chemicals, pharmaceuticals, or other substances of concern. 

How is WBE helping us manage COVID-19?

Wastewater data captures all COVID-19 cases in a defined population, including symptomatic and asymptomatic cases.

The data shows that high levels of traces of SARS-CoV-2 in wastewater are followed by a rise in clinically diagnosed cases, which suggests that this technology can be used as an early warning system. Alberta Heath Services is looking at the data as an additional tool to understand how COVID-19 is spreading in the community.
