Combined wastewater & stormwater discharge to the Gastineau Channel – Second occurrence

The CBJ Utilities Division reports that a second Combined Sewer Overflow (CSO) event occurred at the Outer Drive Pump Station in Downtown Juneau along Egan Drive resulting in a combination of wastewater and storm water being discharged into the Gastineau Channel.  The event occurred at approximately 6:45 p.m. September 10, 2025 and lasted until 2:30 a.m. September 11, 2025.

The second discharge was due to the resumption of heavy precipitation that temporarily overwhelmed the antiquated Outer Drive (OD) wastewater pump station. As stated in the previous notice, the OD station is currently undergoing a major reconstruction project that, once completed, will prevent this type of event from occurring in the future.

Samples of the discharged water appeared to be very dilute in nature. As such, environmental impacts from this second discharge are also expected to be small.  Per Alaska Department of Environmental Conservation (ADEC) permitting requirements, CBJ must provide notice to the public of any CSO event. CBJ has also notified ADEC.
