Reports on untreated sewage

As requested by the Province of Manitoba, we report on the incidents of untreated sewer release into the environment as a result of a disruption to our wastewater collection system. These events are usually the result of something unanticipated like a water main break or a power outage. When sewer operations are disrupted, the sewage can be released into the environment, which helps protect public health and prevent property damage like basement flooding.
