Most Recent Update

February 18, 2017 - 8:08 AM

Regional District of Kootenay Boundary Columbia Pollution Control Treatment Plant is now below permitted discharge levels.

February 17, 2017 - 10:54 AM

Heavy rains and snow melt has caused an overflow at the Regional District of Kootenay Boundary Columbia Pollution Control Treatment Plant. Effluent has been released into the Columbia River. This release occurred over a 24 hour period. 

Due to the significant flow in the Columbia River, the release will dilute fairly quickly. The city of Trail is located upstream from the treatment plant. Sewage volume received by the treatment plant remains relatively constant from day to day. The increased flow to the treatment plant system is primarily rain water and snow melt. As a result, the effluent has already been diluted prior to being released into the river. There are no nearby downstream water intakes at risk and no recreational areas in use at this time. A B.C. Ministry of Environment response officer is monitoring the situation.
