Sewer Main Break - Updates

Emergency-Information

The Town of Black Diamond discovered a Sewer Main break in the area west of Riverwood Crescent, southwest of the Oilfields Regional Arena on September 22, 2018.  Updates to the remediation will be posted here while the work continues.

 Wednesday, October 17/18

The wet weather has been hampering the remediation process on the affected areas, however, this week's sunshine has allowed the Town to access the site again.  Soil removal is being planned and testing is ongoing.  This work is happening with the assistance of an environmental remediation company and is also being monitored by Alberta Environment and Parks.  So far, testing continues to be within acceptable parameters, and the tests will continue as required until remediation is completed.  Until that time, the area of concern remains marked off with yellow caution tape and everyone is reminded to stay away from the area and to keep their pets from entering the area as well.  The area will remain off-limits until remediation is complete.  The Town thanks everyone for their ongoing patience and cooperation.

Thursday, October 4/18

Pumping is completed for the time being, and hoses have been removed from the pathway near the Arena.  Soil and water samples will continue to be monitored.  To-date, samples have been testing within safe limits, but remediation work will still be required.  Wet weather has hampered the remediation process, and that is likely to continue in the immediate future.  The area of concern remains marked off with yellow caution tape and everyone is reminded to stay away from that area and to keep pets from entering the area as well.  The area will remain off-limits until remediation is complete.

Tuesday, Sept. 25/18

The Town has begun to remediate the area affected by the sewer main break.  The first step is to pump down the pond behind the arena.  That process began mid-afternoon on Tuesday, September 25 and will continue until the pond has been sufficiently emptied, allowing itself to recharge naturally with clean fluid.  It is not yet known how long the pumping will take.  The hose being used for this pumping process is located along the pathway near the Oilfields Regional Arena.  At one point, the hose does cross the pathway.  The hose will be simple for most pedestrians to step over.  However, those using scooters, bicycles or strollers may encounter difficulties in using this pathway for the duration of the pumping.  Those persons may want to consider using an alternate route.  Please remember that this hose contains raw sewage, and so should not be tampered with or moved in any way by unauthorized personnel.  Everyone is reminded to stay away from all areas marked with yellow caution tape.

Sunday, Sept. 23/18

The Town is continuing to monitor and work to clean up the contamination from the sewer main break, in conjunction with Alberta Environment and an environmental remediation company.  

Residents (and of course their pets) are asked to stay away from all areas marked with yellow caution tape.  Further updates will be provided as available.
