A three month “Do Not Use” water advisory in the Rosewood Commercial Area has been lifted.

Saskatoon’s Acting General Manager of Transportation and Utilities Angela Gardiner says several tests indicated a potential hydrocarbon contaminant found in a few hydrants didn’t affect the water quality.

But the unknown asphalt-like substance prompted an extensive remediation process as a precaution.

Gardiner says in addition to a high-definition camera probe of the water distribution system, crews conducted high-pressure and regular flushing as well as a thorough scrubbing of the pipes.

Gardiner points out they don’t know how the substance got into the system.

The advisory was issued on May 11th.
